Microservices vs Monolithic Architecture: Which Approach is Suitable for a Start Up?


Monolithic Architecture is a traditional approach in which the entire app is integrated into a single unified model. The prime objective is to interconnect all features making them co-dependent on each other. This model may sound simple, but creates roadblocks in handling bigger and more complex projects.


Microservices architecture, on the other hand, splits an app into smaller services that are interconnected and interact with each other with the help of APIs. Every microservice is independent, loosely coupled, and possesses a distinct hexagonal architecture comprising of business logic and different adapters. Here, each service is a separate codebase, has its own database, and can be deployed independently. This approach has gained momentum these days as modern-day businesses expect more agility in their operations. Some renowned brands using the microservices approach are Uber, Twitter, AWS, Netflix, and Spotify.


This post explores Monolithic and Microservices architecture in detail, outlines their differences and provides suggestions based on specific project requirements. A quick read will help you to pick the best-suited approach for your upcoming software development project.


Monolithic Architecture: Strengths & Weaknesses



Monolithic apps perform speedily at the initial stages as they use local calls in place of API calls throughout the entire network. But, this speed reduces with the expansion of the app. A monolithic app, being a single solution, rather than a set of separate apps, is easily manageable, involve much lower development cost, and encounter very few cross-cutting issues initially.



When the codebase of a monolithic app becomes huge, the IDE slows down, adversely affecting the developers’ productivity. Moreover, it’s challenging to scale the app, and modifying the programming language or framework that hampers the app’s functioning. Also, it’s pretty expensive to migrate to different technology in situations where monolithic architecture is used.


Microservices Architecture: Strengths & Weaknesses



Microservice architectures are well organized - each microservice is responsible for carrying out a particular task, without being concerned about the tasks carried out by the other components. And, since such services are decoupled, they can be effortlessly reconfigured and recomposed to fulfill the needs of various microservice applications. For instance, microservices can serve public API as well as web clients.


Each microservice can be written employing a different technology; for instance, one microservice can be handled by Java developers while the other can involve DotNet developers. Thus, you have the flexibility to choose a particular technology for catering to specific business requirements without having to lock other services with that technology. This helps in optimizing the performance of crucial functions.


Microservices allows you to auto-scale an application as per the load on the app, promises speedier deployment, and eases out rolling updates as there aren’t any dependencies between the services. With this type of architecture, you can execute parallel development by setting up boundaries between various parts of the system; these boundaries are difficult to violate resulting in fewer errors.



Microservices apps consume more memory; involve higher development costs initially; come with complex requirements regarding the operation, testing, deployment, and management; and need a greater level of developmental proficiency and expertise.


Microservices vs Monolithic Architecture: Comparison



Here are some major differences between Microservices and Monolithic architecture based on these crucial parameters.



In Monolithic architecture, the app’s UI, database, business logic, front-end, and back-end are integrated into a single codebase; whereas in microservices architecture, all the aforesaid app elements are subdivided and operated independently of each other. Likewise, the processes of testing and deployment are executed under one line in monolithic apps, while in microservices apps, these processes are scattered across different adapters and databases.


Monolithic architecture is deployed in a traditional format and caters to standard web servers. For deploying microservices, on the other hand, a plethora of approaches are supported - One service-One host approach (each service is deployed to one virtual host machine); One Service-One Container approach (microservices are isolated by docker containers, but resources like frameworks, libraries, and operating servers are shared); and Serverless deployment (third-party cloud services host and manage the servers on which the program runs).



Developing a monolithic application is easy if the app is new, but as the app gets bigger developmental challenges crop up. This is because the huge indivisible database needs the joint effort of the development team.


Microservices, on the other hand, offer loose coupling and several options to choose from while picking the tech stack; but the app developers must possess a more profiled knowledge. However, this structure allows developers to work independently on each component.



Testing is pretty simple in a monolithic app as a single script is used for testing the whole system while testing a microservices application becomes complex as every part of the app needs to be tested separately.



Microservices architecture enables continual development and deployment as every service gets individually implemented. With monolithic architecture, deployment becomes slower.


App Updation

The process of updating a microservices application happens uninterruptedly and doesn’t slow down the entire system. Contrarily, updating a monolithic app is voluminous and burdensome and for every update, the entire app has to be redeployed.



The bigger the monolithic app the more challenging it becomes to scale the app - for handling new changes the entire system has to be redeployed. In microservices apps, each part is scaled independently without downtime and so, involves fewer hassles while carrying out modifications.


Security and Reliability

Monolithic architecture involves a single source code; communication happens within a single unit, resulting in secure data processing and a simple monitoring procedure. Microservices architecture, contrarily, involves inter processing between multiple API connections increasing security threats, and hence, greater security monitoring is needed. However, in monolithic apps, one bug can hamper the whole system, while in microservices apps, one bug affects only that specific service and the bug can be topically fixed. Therefore, even when one service fails other services are not affected.


When should you pick Monolithic Approach?


You intend to develop a Simple App with faster Time-to-market

Monolithic architecture is an ideal choice for building a simple app that doesn’t require reinventing the wheel and the app is unlikely to scale rapidly. Moreover, developing the prototype of a simple app will take place at a fast pace leading to quicker time-to-market.


Smaller-sized Team and No prior Experience with Microservices

Start-ups with smaller-sized teams will benefit from the monolithic approach as experience and expertise in one tech stack will suffice and your team will not have to handle any developmental complexities. Furthermore, if your team doesn’t have any prior experience of working with microservices, picking this approach will be a risky business. In such a scenario, it’s better to start with a monolithic approach and migrate to microservices later on as and when needed.


Your app idea is Novel, Unproven, or the Proof of a Concept

If you have a novel app idea or planning to create a product that is unproven, your application is likely to evolve with time. Here, a monolithic approach will help in iterating the product speedily. Similarly, if your intended app is all set to prove a particular concept, you need to learn more within a short time and monolithic architecture will prove beneficial.


When should you pick Microservices Approach?


Your app is Complex and needs unprecedented Scaling

If you wish to develop a complicated software solution that involves a rich feature set, a substantial amount of personalization, extensive use of interactivity, a huge amount of business logic, or needs to be run by various modules; microservices architecture is your ideal pick. Start-ups who plan to build a highly innovative and revolutionary app that targets a humongous audience base and comes with heavy scaling requirements are recommended to adopt the microservices approach.


Need for Isolated Service Delivery

Microservices work better if you need to deliver independent services speedily. However, for this, you need a sufficient amount of resources as well.


A part of your Platform needs High Efficiency  

For instance, your business is intensively processing petabytes of log volume. In such a scenario, you’ll have to create a service with a super-efficient programming language like C++ whereas the users’ dashboard can be created in Ruby on Rails.


Effortless Team Extension

If you commence your start-up with microservices architecture, your team will get accustomed to the idea of developing small services right from the very beginning and the teams will be segregated by service boundaries. So, later on, you can effortlessly scale up your team as per the need.


When is it advisable to migrate to Microservices Architecture?

It’s time to migrate to microservices architecture when your monolithic app grows big enough to create maintainability issues, when your business functions and their boundaries are crystal clear enough to be converted into individual services, and when your app needs scaling to deal with a humongous user load.


Example: The popular app Netflix started as a monolithic application. With time, the app experienced a surge in the demand leading to issues concerning performance and reliability. As such, the owners migrated their app to the cloud-based microservices architecture. Consequently, the app got segregated into hundreds of microservices and this approach enabled boundless expansion and scaling.


Summing Up:

Monolithic architecture as well as microservices architecture comes with its own set of strengths and challenges. So, when deciding on the most suitable pick for your start-up, you need to first define the requirements of your software development project. If you plan to develop a lightweight app and have budgetary constraints, it’s advisable to go with the monolithic approach. But, if your project is huge with complex requirements or you need to work with futuristic models like Big data, and you can spend on hiring several cross-functional teams, microservices is the most viable option.

Reasons to Pick Ruby on Rails for Web Development Projects!


What factors do you consider while choosing a programming language for your web app development project? Scalability? Level of support? Ease of development? Cost? Availability of libraries? Or all of these? Well, amongst hundreds of programming languages available currently, Ruby on Rails (RoR) is one such language that offers all of these benefits. RoR is quite popular and highly preferred by several companies, right from start-ups to giants as a primary framework for web development. This technology is ideal for creating e-commerce sites as well as healthcare, retail, social media platforms, and content management systems.


Let’s explore the top reasons why Ruby on Rails (RoR) Development is widely chosen for developing web apps.


Why choose Ruby on Rails for Web Development?


RoR is an open-source server-side framework used for cross-platform web development. It ensures fast and easy development of apps. It is written in Ruby, a dynamic and object-oriented programming language. It is distributed under the MIT license.


Take a look at the reasons why RoR is one of the best technologies to invest in!


Own Plug and Play Apps


In RoR, the programmers can develop building blocks for plug-and-play functionality. This allows adopting elements from the current apps built with RoR and using them in future projects. So, the developers don’t need to develop the same elements from scratch. One can develop multi-purpose, expandable apps in RoR.


Also, it is not easy to write user-friendly and structured code. However, RoR has plenty of ready-to-use tools, plugins, modules, and easily configurable components to help the developers write less code with more clarity and high quality.


In some programming languages, analyzing the starting and endpoint of the code is quite difficult. For fixing any issues, one has to start from scratch which can be time-consuming as well as costly. However, this is not the case with RoR. The technology is quite easy to comprehend and involves effortless methodologies for moving the code conventions from one developer to the other.


Moreover, when an application is developed, there could be the need to enhance the app later. And, entrepreneurs who invest in Ruby on Rails, reap the benefits of clean codes that prove to be a savior in this case.


Model-View-Controller (MVC) Architecture


RoR is based on the MVC (Model View Controller) architecture which supports parallel development i.e. many developers can simultaneously work on the app, that too on different pieces of functionalities. RoR has a simple and readable syntax and this enables RoR Developers to execute more tasks with minimal coding. For this reason, developers can implement the tests and evaluate the code, without the need for any third-party testing tools. It has many inbuilt solutions to support a variety of problems and also the support of the Ruby community.


Conventions over Configurations Model


RoR uses the “Convention over Configuration” model which is the key principle and a golden path for the RoR Developers. In this model, the environment (libraries, systems, language, etc.) assumes many logical situations instead of programmer-defined configurations. The developers don’t need to create their own rule every time. As a result, the decisions that the developers have to make while coding is reduced without losing flexibility. They don’t need to spend more time configuring the files. It saves the programming efforts, speeds up the development process, and improves productivity.


Rich Support of Libraries and Components


Ruby on Rails (RoR) Development is blessed with rich libraries, called gems. These libraries can be used to implement features like payment integration, authentication, etc. Also, there are generators in RoR, which enable the automation of basic CRUD functions. Modules are other powerful tools for Ruby developers, which help in the organization of Ruby classes, constants, methods, etc., and unify them into categories. The support of such features and libraries enables faster web app development. This framework also enjoys the support of a massive community that assist RoR developers to address the challenges faced during web development.


High Scalability


Scalability is what every business looks for while selecting a programming language for web development. RoR has high scalability which makes it quite popular. It supports caching out-of-the-box activity and allows viewing of fragment caching within the app’s code. It uses Redis for storing cache. A remote multi-server automation tool can also be implemented to automate the pushing of new app variants to the deployment location. Rails allow you to use Chef, the cloud infrastructure framework written in Ruby. The function of Chef is to manage the infrastructure dependencies, create the folder structures, bootstrap the complete system and update the system configurations with lesser commands. Also, the high scalability of the RoR improves the background activities and ensures a smooth user experience. This can be done using Sidekiq or Resque.


Easy Maintenance and Huge Support


RoR is quite easy to maintain and provides exemplary services due to the advantages of both Ruby and Rails. It is known for its stability and predictability. Adding new functionalities and making changes in the existing code can be done with ease. Especially in the case of bigger projects, upgrading the apps is possible without much complexity. And, if there is a need to substitute the development team, it isn’t a big issue for RoR applications.


RoR has ample support for a large community named RubyGems. They help in solving any issues and hosting solutions.


Key Takeaways:


Some of the most reputed giants like Airbnb, Bloomberg, GitHub, Fiverr, Shopify, Basecamp, etc. have used Ruby on Rails Development Services for their projects. It is suitable for every industry- small or large. Overall, RoR is an excellent option to pick considering the factors like performance, coding, quality, community support, scalability, modifications, etc.


RoR is easy to learn, read and comprehend. It is written in simple English and uses a domain-specific language of its own. It is a well-established language having similarities in integration with languages like Python, Perl, etc. It is based on Agile software development principles which improve productivity and management of the project. Due to all such benefits, its demand has increased among the developers and business owners who want to develop mobile apps.

Let’s explore the kind of services that are outsourced to India and the top reasons why most Fortune 500 companies, as well as small-sized-businesses outsource services to India.


What kind of Services are usually Outsourced to India and why?


IT (Information Technology)


These days, businesses are becoming more dependent on internal IT services like the development of software, website, mobile app, or web app and technical support irrespective of their industry vertical. Nevertheless, engaging in-house teams for IT support is always not feasible, particularly for non-IT firms. Such services need specialized equipment, a specific skillset, and a conducive infrastructure. And, for establishing an IT infrastructure and training the in-house employees with specialized skills; involve time, efforts, and humongous costs.


In such bottleneck situations, the ever-expanding IT industry in India is a viable solution – you get a complete package of specialized skills, enormous experience, proficient software developers, and an already existing IT infrastructure. So, outsourcing app development services to India proves advantageous.


KPO (Knowledge Processing Outsourcing)


Some tasks like analyzing Big Data and research work related to domains like finance, accounting, investment, healthcare, insurance, engineering design, creation of animation or content, market stats, etc. require information processing. Such high-level tasks are no cakewalk as humongous information needs to be processed. Moreover, for carrying out these tasks, one needs to thoroughly understand the business structure and possess the relevant technology to make sure that the processed data is error-free and secure. So, several firms prefer to hire KPO services rather than wasting time, effort, and resources in creating the necessary environment for executing such complex tasks. And, India is the preferred outsourcing location for hiring such services as clients get quality services from talented professionals like engineers and MBAs. Also, Indian outsourcing companies have the technologies and infrastructure needed for all types of knowledge processing tasks.


Customer Support

ECommerce solutions have literally been the game-changer for both, customers as well as business owners. It’s no surprise that businesses are increasingly investing in eCommerce app development. But the question is how to go about it?


In this blog, we have outlined essential steps needed to architect an alluring eCommerce app. Read along for detailed information.


Essential Steps to Create an Amazing eCommerce App


Before understanding the steps to build eCommerce apps, business owners must conduct extensive market research on multiple factors that are mentioned below. Market research will help you to set better business goals, lower business risks, boost customer satisfaction, improve decision-making, outsell competitors, and ultimately make more sales.


Now, let us have a look at the crucial steps that must be followed to create an impeccable app.

Come up with an idea


The first step in this process is to decide the idea and the goals for the app. What do you want your eCommerce app to look like, what should be the overall concept of the app? How will you measure the progress of the app? What are your KPIs? Do you first want to develop a Minimum Viable Product? Using a Business Model Canvas (BMC) can help you understand some important aspects like value prepositions, revenue, customer segments, etc. So having a well-thought-out idea in place is very important to avoid unnecessary expenses later.


Decide your target audience


  • For whom are you creating this app?
  • What is their average age?
  • What are their interests and preferences?
  • Which products do they like and have already bought?
  • How will they find us?
  • Is your service B2B or B2C? Accordingly, the choices of the target audience will change.
  • Look at which mobile and web eCommerce platforms are being used by your target audience.


Answers to such questions will help you to streamline your development process, shape your eCommerce app correctly and even improve the app marketing.


Also, studying the buyer persona is essential to knowing your ideal customers. It includes the needs and preferences of the potential customers, their motivations, and similar data which will influence every factor in the eCommerce mobile app development journey.


Know your Competitors


List out your competitors and do a thorough analysis. Look at their products and services and see what attracts the buyers. Study their business model. However, don’t duplicate their features, business models, etc. Competitor analysis will help you to enhance your research, navigate different challenges in the market, improve your products and services and stand out amongst them, giving a competitive advantage.


Must-have app features


The next step for an eCommerce app development company is to determine the feature requirement of your app. A few of the must-have features that you should include in your app are:


  • Product List and categorization
  • Search Bar and Filters
  • Push Notifications
  • Multiple Payment Options
  • Wishlist
  • Look-books
  • Easy Checkout
  • Social Media Integration
  • Review and Ratings
  • Business Intelligence Tool
  • Synchronization across apps and websites


Decide technology based on budget


To determine the process and the budget, ask yourself the following questions:


  • How much time and resources are you willing to invest in?
  • Do you want to create an MVP model with the least features or want a feature-packed full-fledged eCommerce mobile app?
  • Do you want to develop native apps for both Android and iOS platforms? Or want cross-platform development? Do you also want a PWA?
  • Do you want an expensive backend development with low maintenance or high maintenance third-party APIs having a comparatively low budget?
  • Do you want an expensive backend development with low maintenance or high maintenance third-party APIs having a comparatively low budget?
  • Do you want an expensive backend development with low maintenance or high maintenance third-party APIs having a comparatively low budget?


Once you decide on the above questions, there are different pricing models available to choose from. They are scope-based, time-based, fixed-price models, or you can opt for dedicated resource hiring.


App development


After conducting thorough research on the aforementioned points, you can now start the design and development of your dream eCommerce app.


Follow these tips for a good end result and unparalleled experiences for the users:


  • Ensure that the eCommerce app has user-friendly navigation
  • Remove the excess clutter from the app
  • Incorporate app templates to speed up and streamline processes
  • Incorporate app templates to speed up and streamline processes
  • Give a personal touch to the app with Live Chat support.
  • Use alluring images and animations for better impact
  • Avoid using contrast color combinations, fonts, layouts, etc.


Market your app


Marketing the eCommerce app is equally important as it is to develop it. After all, getting more downloads, views, purchases is the final aim of the app development process. One can create buzz about the app even before its release. Some of the strategies used for successful app marketing are content marketing, SEO optimization, social media marketing, email marketing, paid advertisement, app marketing, etc.


Publish the app


Finally, you are all set to publish your eCommerce app on different mobile app stores like AppStore and Play Store. You can visit the app stores and sign up on their accounts, pay their registration fees, write the description and privacy policy for the app, upload the screenshots of the app interface, upload the app, specify the pricing of the app and your app will be published after it meets the set standards.


Final Words

Want To Optimize React Native Performance? The Dos And Don'ts



Native apps are the way to build mobile applications; however, back in 2015, Facebook (now Meta) saw the opportunity for a React-based framework moving towards mobile development and created React Native to help businesses build hybrid apps.


Created by Facebook in 2015, React Native helps develop iOS, Android, and Microsoft UWP applications. Many businesses are confused or struggling to decide whether to build native or cross-platform apps.


Based on a 2019 Stack Overflow survey, it was found that React Native was the sixth most popular developer framework and many well-known companies use React Native for their mobile apps.


Now, the question is why many companies use React Native for their mobile app?


Let’s see why React Native app development services providers or companies use React Native:


  • It is Fast: It is less time-consuming as the same codebase can be used for both Android and iOS apps except for few changes that needs to be done independently for individual platforms.


  • Apps have Native-like look: React Native developers can get native like look and feel for Android and iOS apps even though single codebase is used.


  • React Native Performance: The apps built with React Native have good performance as this language is optimized well for different mobile devices; also these apps take support of GPU instead of CPU, which enhances their speed and performance.


  • Reliability is not a concern: With big companies such as Airbnb, Instagram and Uber Eats using React Native, you can mark it as tried and tested.


It is developer-friendly: React Native is community-driven, and you can go to Github React Native Community for some solid discussion. There’s also a huge chat server named Reactiflux, where developers can solve their problems.


What matters? The User Experience and React Native Performance


The user experience is the only thing that makes or breaks the app. However, React Native gives almost everything a developer would need to develop an app with great performance.


Most mobile devices come with a 60hz display; a developer gets 16.67 milliseconds to display a frame for the app to deliver great performance. If the app falls short of this, it will result in poor performance, and the UI may even become unresponsive.


Do you want to improve React Native performance? If yes, you should know the dos and don’ts of React Native?

Yes, then let’s help you with that;


The Do’s




1. Use appropriate navigation strategies:


It’s been a long since React Native teams have been working to address problems related to navigation and have fixed a ton of them, but there is a ton left to be fixed to provide a seamless experience.

Difficult navigation between screens may refrain users from using your app.


  • iOS Navigator: Only for iOS and will not help in Android.


  • Navigator: Works only for small application and prototype development. (doesn’t work for complex or high-performance applications)


  • Navigation Experiment: Works well for complex applications, but it’s quite complex while implementing; not everyone prefers it.


  • React Navigation: Used by many apps and often and widely recommended; it is lightweight and works well for both small and large scale applications.


2. Make sure to Cache Images:


Images are a core component being offered by React Native and used to display an image, but there’s no out of box solution for issues such as:


  • Low performance in general and cache loading


  • Image flickering


  • Rendering too many images on a single screen


However, you can easily resolve these issues using third-party libraries, like react-native-fast-image. This library is available for both iOS and Android and works really well.


3. Make use of Animated Library with nativeDriver:


In React Native, the Animated library is one of the most popular ways to render animations in React Native apps.

With the help of nativeDriver, the Animated library sends animations over the native bridge before the animation starts on the screen. It helps execute the animation independent of blocked JavaScript threads which return a smoother and flicker-free experience with no frame dropping.


You need to set the value to true if you want to use nativeDriver with Animated library.


4. Using Appropriate Image size is the key:


Considering React Native performance when the app relies heavily on images, optimizing images is crucial. Rendering this much image will result in high memory usage on a device if the images are not optimized in size; this can even lead to a big blunder like the app may crash.


Here’s how you can optimize the images in the React Native App:



  • Use images that are smaller in size


5. Use the open-source JavaScript engine: ‘Hermes’:


Hermes is an open-source JavaScript engine specifically optimized for mobile applications. Hermes is available for the Android platform since React Native version 0.60.4. The benefit of using it is that it reduces the download size of an App, memory consumption and the TTI (Time to interact) time.


After the React native version 0.64-rc.0 Hermes is also available on the iOS platform.


The Dont’s


1. If you want to Render Huge Lists: Avoid Use of ScrollView:


If you want to display items with scrollable lists in React Native, then there are two ways to implement lists:


  • ScrollView


  • FlatList

Scrollview is easy to implement and is often used to iterate over a list of a finite number of items. This approach is good, but only when the number of items on the list is quite low. Comparatively, using Scrollview with a large amount of data can directly affect the overall React Native performance.


For handling a large set of data in the list format, React Native provides FlatList. In FlatList, the items are lazy-loaded. However, the app does use an inconsistent or excessive amount of memory.


2. Don’t forget to remove all console statements:


Console statements are necessary for debugging JavaScript codes, but they are only for development purposes. If you forget to remove these statements before bundling, these statements could cause serious React Native performance issues.


You could also use plugins such as babel-plugin-transform-remove-console to remove these statements from production. However, you can remove it manually if you don’t want to add additional dependencies to your React Native application.


3. Refrain from Updating state or dispatch Actions in componentWillUpdate:


You can go for the componentWillUpdate lifecycle method to prepare for an update. If you aim to set a state, you can easily do that with the help of componentWillReceiveProps instead, or if you want to play safe, then use componentDidUpdate instead of componentWillReceiveProps to dispatch any Redux actions


4. Unnecessary libraries and features; Remove it all:


Each library comes with a footprint left on your React or React Native application. Therefore, you should only add libraries and features that you need and remove all other irrelevant dependencies. Navigations, Animations, tabs and other features influence the screen load time, so the lesser, the better.


5. Anonymous Functions While Rendering; Avoid it:


What developers call a bad practice is ‘creating functions in render()’ because it leads to serious React Native performance issues. A different callback is created each time a component re-renders, which is not a problem for smaller components.


However, when it comes to PureComponents and React.memo() or when the function is passed as a prop to a child component, it becomes a serious problem.


Instagram: Making the right use of React Native


The creator of React Native, Meta’s owned photo-sharing social platform Instagram, is one great example.


Instagram’s primary operation mode is digital photography and short videos now. Back in 2016, Instagram seriously thought of switching to Reactive Native, post-integration with existing technology was a challenge, but now they can push features faster, smoothly and maintain both iOS and Android App versions.



The open-source React Native framework creates cross-platform mobile applications. JavaScript being the core, it also has components for building interfaces and functionalities. It’s a popular framework that delivers a seamless experience at scale.
React Native offers businesses the ease and opportunity to create mobile apps differently than what seemed possible a decade ago, when you could build native-like apps, but you could just use one programming language like Java.
These days, things are different, companies have made grand improvements on both iOS and Android platforms, but such improvements require the help of qualified React Native developers.

Expert Guidance on debugging React Native Apps: Recommended Practices and Handy Tools!



Debugging is one of the crucial activity during the software development. It refers to the process of identifying an error in a software application that causes performance issues, then analyzing the issue, and finally resolving it. Debugging allows you to validate your code and fix issues before pushing a software application into the production stage. However, debugging issues are likely to arise during various phases – development, testing, and even production/post-deployment. And, implementing the right debugging tools and methodologies will speed up development and enhance the efficiency of the end-product.


Coming to React Native debugging; the framework is made up of different environments, the most prominent being Android and iOS. As a result, it becomes challenging to debug apps due to multiple platforms involved. Moreover, React Native offers a huge variety of tools for debugging which seems confusing for many, particularly newbies. This post guides you through some effective practices and useful React Native and React debugger tools that will help you to identify issues and fix them like an expert.


React Native Debugging Methodologies and Best Practices


Identifying and Addressing Console Errors, Warnings, and Logs


Console errors and warnings are visible in the form of on-screen notifications with a red or yellow badge.




Errors will be displayed inside a RedBox with the command console.error(). This RedBox contains a description of the error and also a suggestion on how to resolve the error. Take a look at this example. If you write a style property that the React Native framework doesn’t support, or if you write a property meant to be used for a particular element (like a backroundImage needs to be set for the element View), then the RedBox shows an error along with the list of supported style properties that can be applied to the View.




Warnings will be displayed inside a YellowBox with the command console.warn()Such warnings include information on performance-related issues and deprecated code. Most of these warnings indicate some bad practice within your code. Examples of warnings include a notification about the presence of an eventListener that isn’t being removed, the presence of deprecated features and dependencies, etc.




For issuing logs, either use the command react-native log-android or use the Chrome console with the command console.log(string str)


React Native developers can hide the notifications concerning errors and warnings with the command LogBox.ignoreAllLogs() whenever needed, like during product demos. You can also hide the notifications on the basis of per-log with the command LogBox.ignoreLogs(). This method works in scenarios when a noisy warning cannot be resolved like the ones in a third-party dependency. But, whenever you ignore logs, make sure to create a task for fixing those ignored logs later.


Debugging using React Native’s built-in Debug Mode


Check out how to utilize the built-in debug mode offered by the React Native eco-system employing browsers like Safari or Chrome.


Debugging with Chrome


Install these react-devtools for supporting React Native: Yarn and NPM. Then use the development mode to open the in-app developer menu; here you start the debugging process by activating the debug option.


From the Developer Menu, select the option Debug JS Remotely. This action opens up a channel to a JS debugger. A new tab opens; here, from the Chrome menu, choose Tools – Developer Tools; for opening the devtools.


The other most prominent options to utilize in the in-app developer menu to debug apps are:


Enable Live Reload: for automatically reloading the app, Enable Hot Reloading: for identifying the modifications that result in a changed file, and Start Systrace starts the Android marker-based profiling tool. The option Toggle Inspector helps in toggling an inspector interface. This way, developers can inspect UI elements present on the screen and examine their properties. Then an interface is presented; this interface contains other tabs such as networking for displaying the HTTP calls as well as a performance-related tab. The option Show Perf Monitor tracks your app’s performance.


Debugging with Safari


Your app’s iOS version can be debugged using Safari, and here, you do not have to enable “Debug JS Remotely”. Simply open Preferences and then select the following options:

  • Preferences
  • Advanced
  • Show Develop menu in the menu bar


Next, choose the JSContext of your application:


Develop – Simulator – JSContext


Now, the Web Inspector of Safari is going to open and you would be able to view a Debugger and a Console. And, each time you reload the app, either manually or by using the fast refresh (live reload), a new JSContext will get created. Remember to select the option Automatically Show Web Inspectors for JSContexts; otherwise, the latest JSContext will be selected manually.


Prominent React/React Native Debugger Tools


React DevTools


This set of React tools is employed for debugging the component hierarchy of React and works well for front-end operations. Using this toolset, you can view what’s there deep within your component tree – select the options state of the component and edit the current props.


React Developer Tools are the extension to the browsers Firefox and Chrome. However, to debug apps built in React Native, you need to use an autonomous version of React DevTools and run this command on your terminal – npm install –g react-devtools. Then launch the app by running the command react-devtools; select the option Show Inspector from the in-app developer menu for examining the app’s UI elements.


If Redux is used, then you need to use React DevTools along with ReduxDev Tools to fully understand your component’s state. For this, Redux DevTools need to be separately installed and here, the tool React Native Debugger proves quite useful as well.


React Native Debugger


The React Native Debugger is immensely beneficial if Redux is used during React Native app development. This is a standalone tool that functions on Linux, Windows, and macOS. This tool is used for logging or deleting Async Storage content, detecting as well as diagnosing performance issues, and examining network requests.


The best part is that it integrates React DevTools as well as Redux DevTools within a single app and so, there’s no need for using two separate applications to debug apps for the React and Redux environments. The tool offers interfaces where you can examine and debug React elements and also view Redux logs and the related actions.


React Native debugger outshines Chrome DevTools in employing the toggle inspector for inspecting React Native elements. Besides, React Native debugger provides the functionality for editing styles; this feature is not present in Chrome DevTools.




Flipper is a cross-platform tool used to debug JavaScript apps as well as the device and JS logs. It launches simulators for managing devices, can connect with several devices simultaneously to debug apps across multiple platforms, and involves a single-step debugging process including watchpoints and breakpoints.


Flipper edits the components on the fly, then reflects those edits in real-time within the application, and integrates with the app’s Layout Inspector. Its capability of integrated launch management enables developers to define configurations and employ them for unit testing, without having to replicate configurations in several places. Moreover, comes with a plugin-based architecture and myriad handy features; more features are expected in the coming years.


With Flipper, you can view, inspect, and control your apps using a simple desktop interface. Flipper can be used as it is or extended employing the plugin API.

Bottom Line


The aforesaid tools and methodologies enable you to debug apps more efficiently and flawlessly, just like a pro. These tools and best practices work wonders to speed up development, enhance developer productivity, and improve the performance of the end product.

The Importance of Payment Gateway Integration In iOS And Android Apps

Do you carry cash everywhere or a smartphone?


Don't we all shop from our smartphones? Lately, mobile payments have gained prominence by providing a fast and easy way to make purchases and helping users save time and get an enhanced shopping experience.


How do we make the payment then? Of course, with the help of online payment options using payment gateways. Whether you talk about Retail companies, or you are on e-Commerce stores, freelancing platforms, travel agencies, they all are using payment gateways to help ease your payment.


Based on Statista’s website, by 2023, there will be around 1.31 billion proximity mobile payment transactions by users worldwide.


The payment gateway integration is not subject to one mobile OS; it's for both Android and iOS. These two OS’s have captured the entire global market, as we all know. Let's uncover the crucial aspects of integrating payment methods for both Android and iOS.


Let's start with;

 What is a payment gateway?


Payment gateways are the median between online customers and financial institutions. Without intermediaries, in-app purchases and payment processes can't take place.


As we see, many apps like Amazon, Netflix, etc., ask for a subscription to watch shows, movies, etc. While paying for a subscription, it gets easy as, within a few steps, users can buy the subscription via the third-party app (Google Pay, PayPal).


The funds move through an interbank network, a complex sequence of operations and create risk associated with security assurance. It just takes users a few seconds, but it's a huge amount of work to deal with underneath the app.


Fortunately, banks take responsibility for all transactions and data safety, but how do you deliver this information to the bank? How will the application know that the customer has funds in his accounts and the account belongs to the customer?


Moreover, what about storing your payment details? What if all this information gets in the hands of the wrong people? Who is responsible for this? Both business owners and mobile app developers should not be the ones to bear this blame.


To get deep insights, let's now understand how a payment gateway works?

  • Before opting for payment, users open a cart to buy the items they like. After doing so, they go to payment, wherein you have to enter debit or credit card details.
  • The information you fill in is sent to a payment gateway system. It then encrypts user data and passes it to a payment processor.
  • The payment processor is another mediator that begins the transaction process and gets feedback from the bank (Visa or Mastercard).
  • The processor verifies the data accuracy and then transmits the information to the bank (financial institution), which has to finalize the verification (it takes seconds).
  • After approval, the amount is withdrawn from the buyer's card and sent to the merchant's account.


Why choose payment gateway integration?


Considering the USA market, one can expect the USA Digital payment market to register a CAGR (Compound Annual Growth Rate) of 12.14% over the forecast period from 2022 to 2025 (Source: Statista). Hence, it has become the most important aspect of any business.


The positive thing is that it allows collecting money through the customer's preferred bank without risking sensitive data.


With the increasing awareness about the ease of online transactions and digital evolvement, consumers are changing their priorities for making payments online. Hence it generates confidence among the users for switching to online transactions, which is why we see the boost in payment gateways.


Here we will see what the trend globally looks like:


In the year 2020, the size of the mobile payment market across the globe was valued at 1.54 trillion USD.  This value rose to 1.97 trillion USD in 2021. The market has been predicted to grow at a CAGR of 29.1% from 2021 to 2028 and reach 11.83 trillion USD by 2028.





How to do the integration of payment gateway with iOS and Android?


  1. Install the app or any type of payment gateway based on your needs, such as the size of the business, industry or the targeted country.
  2. One should add client tokens when the server sends a request from your app. It helps generate a new token on every app launch with full authorization and configuration specifics to let the client initialize the SDK. One can execute it using various programming languages like JavaScript, React, NET, PHP, Python etc.
  3. Then the software developers will test the credentials such as customer id, public and private keys etc.
  4. It is important to install additional certifications that accept the PCI-DSS for better security. Further, the Secure Sockets Layer (SSL) guarantees clients' sensitive information protection.
  5. While processing a transaction, the one-time payment method needs to be configured. It works as: the client sends you card information, the gateways forward it to the server and uses that data to initiate the transaction.

How to know the best applicable payment apps for you?


Firstly, make sure the payment gateway supports your product.

 Many payment gateway providers support both digital and physical products. However, not everyone does that, plus some product groups are riskier, so the providers don't join in.

For example, Stripe has Restricted Businesses, including investment and credit services, gambling, adult content and services, get-rich-quick schemes, and many other categories.

 Thus, you must be sure you're on the "white list" of a particular provider.


Pay attention to pricing


When it comes to payment gateway integration, keep in mind these fee types: monthly fee, gateway setup, merchant account setup, and per-transaction fee.


Dig through gateway documentation to ensure there are no hidden fee charges and the pricing policy is crystal clear.


Check payment methods and card types


You should always list payment tools and services used by your audience and make sure that a payment gateway of your choice supports all of them.


The integration of digital wallet payments differs from payment card support because of different tokenization processes. You must check if a payment gateway allows using mobile wallets.


Another essential point is that if you are targeting the international market, check the cost for businesses and multi-currency payments as some gateways require additional fees.


Study transaction limits


Payment gateways often have limitations for the numbers or amounts of transactions to take place. For example, Square's maximum transaction is 50,000 USD. This amount is enough for most businesses but may not be the same for you. Anything beyond this limit needs to be split into different instalments.


Look closely at merchant account options

A merchant account is an intermediary account where payments are parked before you get them, a kind of money storage. It is basically for a smooth shopping experience. At times buyers want to return the product or get a refund. To clear such issues easily, one can manage them with the money accumulated in your merchant account.


Well, when we talk about merchant accounts; then there are two types to know about:

First is a dedicated account that is for your business only. It helps you to control your money and operations. Companies with dedicated accounts usually receive faster transactions, but paying a higher price is also necessary to obtain the shortages.


The second is an aggregated account for several merchants (businesses). Mostly, entrepreneurs pick this option as it's cheaper and easier to set up (it takes less than 24 hours).


The Use Case: Square


Currently, three payment apps mostly applicable for payment gateway integration are Square, Stripe, and PayPal.


Square is the application that provides an all-round top choice for making payments in different ways (online, invoices, in-person, over the phone). It comes with many free features, a powerful POS app, and attractive equipment options.


Square acquired many companies, including Storehouse, Fastbite, and Kili. Major competitors for Square are Google Wallet (GOOGL), Intuit Inc. (INTU), and PayPal-owned (PYPL) Venmo.


Let's see what Square provided to a company named Kili (developed silicon, electronics, and software that simplify and optimize payment processing) after the acquisition.

While Square already offers a payment option to the users of credit cards via mobile, the Kili acquisition will let the company begin experimenting with Near Field Communication (NFC) payments (like Apple Pay). It will help compete with larger companies by delivering simple and affordable hardware that gives the sellers a safe and smart way to do business.




Does your company deal with any kind of online transaction? You need to allow payments in your mobile app. Using a payment gateway will give you a competitive advantage. The payment gateway is the connecting link between the bank and the customer and removes the hassles associated with safe data storage, transaction security and fraud detection.

The Essential Features and Cost of building a Messaging App like Signal!



 mobile app development
WhatsApp used to be the most popular messaging app, but not anymore, ever since its revised privacy policy was declared in January 2021. This policy asked users to share their personal information to Facebook. Needless to say, this declaration has adversely affected WhatsApp’s sky-high popularity as one of the most secure and encrypted messaging options. And, the Signal messaging app, which was earlier unnoticed by messaging app users, started to be adopted as the ideal replacement for safe messaging.
Signal has gained an undisputed reputation of keeping users’ chats and calls truly encrypted and private. Even high-profile users like Elon Musk, Brian Action, and Edward Snowden have endorsed Signal’s uncontested privacy quotient, because of the level of secrecy and security it offers.
Investing in a messaging app like Signal is a brilliant idea and many of you must have already started the app ideation process as well! So, this post explores the unique selling points of Signal, the necessary features to include while building a Signal-like app, and provides an approximate idea on signal app development cost.

Signal App: An overview

Signal is a cross-platform messaging application that follows the approach of app models like Red Phone and Text Secure. It has bagged the reputation of being the most encrypted and secure application available in the market. Signal, being open-sourced; its source code is available on GitHub and can be accessed easily.
Using Signal chat, users can avail of one-to-one messaging as well as group chatting in the most secure manner possible. Users can share images, voice notes, files, and videos and make video/audio calls without having to worry about the risks of account hacks or data breaches. The reason is that Signal adheres to highly encrypted messaging protocols like Double Ratchet Algorithm, Extended Triple Diffie-Hellman, HMAC-SHA256, Curve25519, and AES-256, to rule out any chances of MITM (man-in-the-middle) hacking attempts. Moreover, all calls and messages that take place over the app are end-to-end encrypted, such that even Signal cannot access users’ data. Furthermore, the app doesn’t allow users to take a screenshot.
This revolutionary app has been created by the Signal Technology Foundation and the Signal messenger LLC.

Signal’s Unique Functioning Protocol to ensure Security

Here’s how an encrypted messaging application works!
When the app is installed on a smartphone, a permanent key pair gets created. This key pair consists of a “public” and a “private” key that are meant to encrypt and decrypt messages. The process of encrypting and decrypting works like this – the “public” key is sent to the messaging server for identifying users and the private key stays within the users’ smartphones. And, if this private key is compromised, the users’ messages become vulnerable to security threats like decryption and misuse.
The Signal messenger uses a more secured protocol. It generates several temporary key pairs besides their permanent keys. This function empowers the app to change the key after each message. When a user sends a message to another user via Signal, it integrates the temporary and permanent pairs of public as well as private keys for both the users to create a shared secret key. This secret key encrypts and decrypts the message. And, as the private keys of users must be accessed for generating the secret key, the secret key stays only on the devices of the users involved in the messaging act.
Moreover, Signal adheres to the protocol of continuously replenishing keys for each user, and this function allows the app to acquire new shared keys after each message. Also, features like disappearing messages, turning off the lock screen notification option, blurred photos, and encrypted calls; tighten the app’s security further.

Essential Features to include in your Signal-like Chat/Messaging App

Real-time Messaging and Object Sharing
Real-time messaging is a core prerequisite; using this feature users enjoy real-time interaction from any part of the globe. The multiple object-sharing features enable users to share media, documents, contacts, and even their present location with other users either privately or via group messaging.
In-app Audio/Video Calling
The in-app audio/video calling feature is a must-have in messaging apps as it allows individuals across the globe to connect with each other from one single platform.
Privately encrypted chats
This functionality needs to be integrated into your messaging application as it restricts server access to metadata including chats, icons, titles, and membership icons.
Inviting Friends
Users should be able to invite their friends/acquaintances. So, your app should integrate “invite friends” feature that will request users to provide access to their contact details for inviting friends or acquaintances. This way, the users will be able to send the invitation link directly to the individuals they wish to add.
Disappearing Messages & Lockable Chats
The disappearing messages and lockable chat features provide users the flexibility to maintain the privacy of their personal life. Users can set a timer of their choice – 5 seconds, or even one week. After the end of the timeline chosen by the user, the messages will disappear automatically, without being stored in any cloud server.
“Delete for Everyone” feature
Signal allows one to delete messages (for everyone) unlike WhatsApp. Hence, users have the option to delete messages sent by mistake or simply if they wish to do so. So, integrating such a feature will attract users.
Voice over Internet Protocol
VoIP or the Voice over Internet Protocol feature is crucial as it offers a stable internet connection for ensuring an enriching communication experience, even during times of slower internet connectivity.
Support for Proxy Version
The proxy feature enables users to use the app seamlessly regardless of their location, even on instances when the app is blocked in some country. But, how? In Signal messaging, the proxy settings allow the user to make the necessary modifications for accessing the app since the data traffic remains opaque to the person who’s operating the proxy feature.

Wearable App Development: Cost Estimate & Factors that affect the Development Expenses!



Today, a huge chunk of tech-savvy individuals own fitness bands, smartwatches, and hands-free GPS systems. Such wearable devices are empowered with new-fangled sensors, microprocessors, and chips supported by robust operating systems. And, just like smartphones, modern wearables support various apps that can be used for syncing data from users’ devices.


Wearable technology has worked wonders to enhance the convenience quotient of modern-day individuals. Here are some instances!


Using Recordr, an Android wearable app, users can record sounds from their surroundings by simply tapping an icon placed on the right side of their smartwatches.

Spotify enables users to listen to uninterrupted music, scroll through the playlists, adjust the volume, etc. without having to use a smartphone.


Travelers can gather crucial information concerning cabs, buses, trains, ferries, etc. with the Citymapper app installed in their smartwatches.


No wonder, the popularity and demand of wearable apps are skyrocketing! As such, entrepreneurs are keen to build wearable apps. And, many of you would like to get a rough idea about the development expenses. So, I have penned down the factors that affect the wearable app cost and provided an estimate on the developmental expenses.


Factors affecting the Wearable App Development Cost



Extensive Research

Researching about the market and user base for understanding the specific requirements of target users, is an essential practice. This activity helps the software company to clearly define the project scope, eliminates unwanted glitches during wearable application development, and ensures the creation of an impeccable application. But, this research consumes a considerable amount of time and efforts. Most of the firms do charge for market research and this activity affects the price estimation of the project for sure.


UI Design of the App


The UI design of a wearable app is way different from that of an application developed for a tablet or mobile device. For example, a smartwatch needs to have four major interaction points – faces of the watch, voice commands, notifications, and independent wear native- based applications.


Watch Face: If the app is time-based, a watch-like look and feel need to be created.


Voice commands: Integrating the voice command feature within a wearable is trending these days. This feature enables users to use their voices for initiating commands. So, special attention and extra efforts are needed for crafting a voice-based user interface.


Notifications: Notifications display contextual and movable data, and deliver a seamless user experience. This feature helps users in replying to messages, searching for a location using a map, playing their favorite songs, and many more.


Wear Apps: These apps are likely to function without any smartphone connectivity. For building such independent applications, you may either follow a similar approach as in mobile app development or reinvent the wheel as per your specific needs.


Platforms/Devices Targeted


The kind of hardware devices and software platforms targeted affect wearable app costs to a great extent.


For instance, let’s compare the expenses involved for the Android and iOS platforms. Many of us are of the opinion that wearable development for the Android platform is less complex and involves lower costs. But, in reality, developing wearables for the iOS platform is speedier and more cost-efficient. The reason is Android OS powers a wide range of wearable devices. So, Android developers have to scale the app accordingly for providing support to varying screen sizes. And, the development costs for various screen sizes differ. Therefore, Android app development is costlier and time-consuming. Coming to iOS, it powers limited devices, resulting in lower development costs as well as faster time-to-market.


The Development Procedure


Wearable app development is slightly different from the standard mobile app development process. Android development involves fewer interactions, has access to standard Android APIs, and also leverages the APIs as well as features of a smartwatch. iOS development, too, comes with its set of specific requirements that spikes the wearable app cost. The good news is that Apple has launched a new version namely watchOS 6 along with some APIs that will enable in delivering a robust UX; and features that support developing autonomous watch applications.


App Testing Challenges


The testing and maintenance costs are higher for wearable apps as compared to other mobile app categories. The reasons are as follows:


Screen size: Wearable apps target varying screen sizes and so, need to test the app’s

performance on different sized screens.


Battery Life: The battery life of the primary device needs to be tested extensively. For this, different instances are to be considered. One instance involves switching off the primary device to check how the data gets affected.


Data Syncing: To test the data syncing between a mobile app and its connected wearable app one needs to watch out for various scenarios like what happens when one of the devices gets switched off, how does the app perform when the Bluetooth connection gets lost, and so on.


A Dearth of Emulators: There are a few emulators available in the market and this expedites the Wearable app cost.


Post Launch Support/Maintenance


Newly launched wearable apps are likely to encounter unexpected glitches, downtime, or software failures. Needless to say, it’s advisable to hire technical support/maintenance wearable app development services for keeping up an app’s performance standards, preventing downtime, and averting incidents of wearable app failure when the load is high. These support services may be needed for multiple weeks post-app launch and incur additional expenses.


Location of the App Development Team


Wearable app cost is heavily dependent on the location of the app development center as the rates of hiring wearable app developers are not the same in every country/region. Take a look at the hourly rates for hiring developers from these regions:


India – between $10 and $75 per hour


Eastern European region – between $20 and $110 per hour


South American region – between $25 and $120 per hour


Australia – between $35 and $150 per hour


The UK – between $35 and $175 per hour


North America – between $20 and $250 per hour


So, your development cost revolves around the location of your outsourcing partner. Here, North America is the most expensive option and India is the most cost-efficient choice.


Wearable App Categories: Cost Estimate


Here’s a rough estimate of the expenses likely to be incurred for building a wearable app based on their categories. The average cost range of building the following categories of wearable apps are as follows:


A Fitness app like Fitbit – between $ 28,000 and $ 35,000


An app like Starbucks – between $ 70,000 and $ 100,000


A media-sharing app like Instagram – between $ 120,000 and $ 150,000


An app like Airbnb – between $ 140,000 and $ 200,000


An eCommerce app – between $ 200,000 and $ 250,000


Final Thoughts

I hope, my esteemed readers are now well versed in estimating the cost of their upcoming wearable app development project and have clearly understood the major factors that drive the wearable app cost.

All-inclusive insights on Building JavaScript microservices with Node.js!

Is the size of your JavaScript app growing rapidly? If yes, then it must have become challenging for you to maintain the code, fix bugs, and implement new updates. So, what’s the solution? Well hiring more developers can be helpful, but at the same time might increase the project complexity and spike expenses.

The best solution is to go for microservices architecture– distributed systems that split up large monolithic designs into smaller-sized independent programs that intercommunicate for carrying out operations and exchanging data. Using this approach an app can be structured as an amalgamation of loosely coupled services.

Let’s explore JavaScript microservices in detail and understand why it is advisable to use Node.js architecture for building microservices. Also, get step-by-step guidance for building JavaScript microservices with Node.js.


What is meant by microservices?


In terms of software app development, microservices refer to a type of SOA (service-oriented architecture). Here, an assembly of interconnected services forms the app structure. Because of microservices, the architecture of the app is created using lightweight protocols such as LDAP, OpenLDAP, etc. App can be disintegrated into smaller services, and there’s room for enhanced modularity. These days, most of the cloud-based applications with a GraphQL/REST interface are developed employing microservices.


Advantages of Microservices over Monolithic Architecture


In Monolithic Architecture, the predecessor of microservices, all the software components, and services are put inside one large container and then packed tightly. While a monolithic app is a sole unified unit, microservices break the app structure into smaller independent units that execute each app process as a distinct service. Therefore, every service has its own logic and database and performs specific functions. So, as compared to monolithic apps, microservices apps are more flexible, scalable, reliable, and language agonistic; involve lighter iterations; optimize time to the fullest; organize data systematically. Moreover, the interfaces of microservices (API endpoints) contain a base URI. This URI identifies a data object and the standard HTTP methodologies such as POST, GET, PUT, PATCH, and DELETE that are used for manipulating the object.


In the case of apps built on JavaScript microservices, you can focus on creating monofunctional modules having precise interfaces and clearly defined operations. This makes the app developmental process more agile, minimizing the hassles of continuous testing.


However, since each microservice must be dealt with separately during activities like testing, deployment, caching, etc. this approach doesn’t suit all kinds of projects. Ideally, it’s advisable to use monolithic architecture when developing lightweight applications/software solutions that do not use much business logic. Microservices are recommended for building complex apps and evolving apps with scaling requirements like in SaaS solutions that may have a thousand users one day and ten thousand users the next day. 


Node.js Microservices:



Node.js is the most preferred choice for building JavaScript microservices. Node.js is an open-source, cross-platform RTE (runtime environment) written in a JavaScript engine and is used for developing server-side and networking apps. Node.js is executed on operating systems like Linux, Microsoft Windows, and OS X within the Node.js runtime.


Why is Node.js preferred for creating microservices?


The Node.js framework offers a rich database containing several JavaScript modules that eases out the development of JavaScript microservices. It is a preferred technology for building I/O bound apps, JSON API-based apps, SPAs, real-time apps that are data-intensive, data streaming apps, etc. The benefits of using Node.js for microservices development are as follows:

Asynchronous Nature: The non-synchronous and non-blocking libraries of the Node.js environment, move on to the next API without waiting for the previous API to return data.


Greater Cost control: Both Node.js and microservices have exceptional scaling abilities resulting in lower development and maintenance costs. Moreover, Node.js minimizes the infrastructure requirements, like memory, CPU, etc. for serving the same number of requests as compared to others, thereby lowering expenses.


Great performance: Node.js is a popular web technology with dynamic community support and plenty of available resources. Besides, Node.js offers a standard streaming API and so ensures the secure development and sound performance of real-time apps like online gaming, chat apps, etc. Also, if one microservice is down due to issues or bugs, the entire app doesn’t get affected And, JavaScript, being an interpreted language, saves time during the compilation stage. That’s why apps that employ JavaScript microservices with Node.js perform well.


Speed and Responsiveness:


Node.js is single-threaded and, owing to event looping, the server employs a non-blocking mechanism for responding. Moreover, because of the notification “Events of Node.js”, the app server can capture the response of the previous API call. Buffering is minimal as data is released in chunks. Coming to speed, the V8 JavaScript engine enables Node.js developers to execute codes very fast.


Node.js Use Cases Scenario


 Node.js is a perfect fit for the following use case scenarios:

  • You are building an enterprise application that needs to support various clients, native mobile apps, and mobile/desktop browsers; provide an API that third-parties can use, set up a continuous deployment pipeline for an app; integrate with other apps through a message broker or web services; and run several instances of the app on various machines for catering to the availability & scalability requirements of NFR.
  • You need to migrate monolithic apps for enhancing aspects/abilities like flexibility, scalability, and manageability or you have to re-platform a legacy application.
  • You have to segregate independent end-to-end services like authentication and encryption.
  • A scenario when the service provider offers the required infrastructure management and computing resources to the customer like pricing or forecasting services.
  • You have to offer back-end services for a front-end responsive web app that is likely to collect data from various data sources or channels.


Steps for building JavaScript Microservices with Node.js


Validate the Business Requirement


Identify which services your business needs. For instance, you need a service where two ZIP codes and the distance between them needs to be identified. Validation techniques are required to be used to identify the ZIP code and calculating the distance. For this, this micro service needs to configure external API calls. And, if you implement an internal cache, process can become cost-effective by speedily duplicating the API calls.


The Initialization Procedure


At first, Install Node.js on your workstation/computer and for this, the 8.1.1 version is recommended. The Node.js Packet Manager, commonly called NPM, comes as a part of the installation suite. NPM carries out crucial functions like project launching, dependency loading, and service execution.


Foe project initialization, open the Node.js platform, go to the root folder and then, run the command $ npm init. After the command gets executed, it makes way for the creation of the package.json file, and the creation of this file forms the foundation of project execution.


The microservice would get created based on these two primary packages –


  • “Request” – microservices use this package for connecting with web-based or third-party APIs.
  • “Express.” – This package provides a structure for supports Node.js apps and supports the Node.js foundation of that microservice.

These packages can be added to the package.json file by these simple steps – entering the command $ npm install express request, adding save at the end of the command, and then running this command.




The mpm init command creates a structure of files/folders for building a microservice and the Request and Express packages are saved within this structure in the form of dependencies. Thereafter, coding begins.


Set up the Server


This step is the first part of coding and here you need to create a server that recognizes and accepts requests.

Create an entry file named server.js; it will be executed when the server starts. Make the routes available in the primary file by passing the app’s instance in the routes object. Then define the routes and when you run the server, the app listens to either port 3000 or any other port that is specified in the variable of the PORT environment.


Specify the routes


Then comes the next crucial step in microservice development, of specifying the routes for response transmission. The server built earlier will assign routes and these routes will make sure that all the requests are processed.


Create a file named routes.js in your api_routes folder and add the required code to it. Now, the routes file specifies the two endpoints – the about endpoint specifies the app details, while the distance endpoint computes the distance (in miles) between both zipcodes using the external API.


The controller file contains the implementation of these endpoints and will get us to the next step.


Build the Controller


Now the controller logic has to be added to the microservice to empower it with some useful functions. The controller object is used for interpreting the user intentions as well as actions to communicate the newly changed data for processing objects. It is also useful in handling requests received by the routes module that was created before. The controller file executes two functions – getDistance() and about().

Two arguments – request & response – are accepted by the about() function. Their names, as well as version values, get stored in the properties of package.json. Likewise, the getDistance () function also contains the request & response pair of arguments; it calls the function find API that has been defined in the services folder.


Establish the External API Call


For creating the API call, employ a third-party API, ZipCodeAPI.com. – one can obtain a free API key by registering for an account or using the test API key.

Now, create the microservice code through the following steps:

  • Load the request package for processing the external HTTP request
  • Load the API key and zipCodeURL available in the environment variable

Build a request object under the find()function option, and then specify a callback function that will be called on receiving the response. This step is successfully executed if the aforesaid function is without errors and the response contains an HTTP status code 200. Thereafter, the body of the response is parsed and then returned. If the response is parsed instead of forwarding it directly, the response can be handled with optimum efficiency.  In case of any failures, they get logged to the console and the response of -1 gets returned.


Executing the Program


Now, execute the program by running the npm start command in your project’s terminal. If all functions run smoothly, hit the option /about web endpoint and view this output on a web browser – {“name”: “microservices”, “version”: “1.0.0”}


Also, hit the /distance endpoint option and pass some values to it through the query string; then the desired output will be produced.


Here, the distance of the object is exported. The controller is able to represent the concrete functions and instances of the external API calls as desired. And finally, for completing the microservices execution process, the code is reviewed for detecting any typos within the command.


This is an example of building a microservice for finding the distance between two ZIP codes.


Integrate a Database into your Architecture


Now, your Node.js app is created and the data needs to be stored in a database. For this, you can use a Data API or a database. And, for seamless interaction with your databases from the Node.js app, employ a JavaScript driver.


Concluding Words:


I hope this post has helped you to gather handy information on building JavaScript microservices using the Node.js framework and you have clearly understood the process of building microservices.

List of Top Local Databases used for React Native App Development in 2022!

React Native has become the most talked-about technology in the last couple of years. Its popularity as a cross-platform framework due to cost efficiency has made React Native Development the most preferred development technology in the tech world. Due to the ever-growing demand, developers are expected to build highly performant apps. One of the challenging decisions while architecting React Native apps is to select the right database for the project. The good news is, that the React Native framework comes with some really good choices available for data storage. So, in this blog, we will shed light on top React Native databases for 2022. Let’s explore them in detail. But before that, let’s quickly run through the significant factors that should be considered while choosing the apt database for React Native projects.


Variables to be considered while choosing the Apt Database for Your Project


Data and App Complexity: complex data sets in the applications can cause severe app performance issues. So, databases that can store complex data should be chosen. Apps that have lower complexity can use simple databases so that such apps can be easily synced with the server. But complicated apps with multiple-user collaboration requirements require a complex database for ensuring seamless syncing.


Memory Handling: Inadequate database memory management can lead to the crashing of apps. Hence, it should be ensured that memory management is done efficiently through processes like compaction, garbage collection, etc.


Line of Codes: If a higher number of code lines are used in a project for CRUD-like operations, then an advanced database should not be the choice as the coding gets more cumbersome. This code complication deteriorates the performance of the app significantly.


Data Conflicts: the possibility of data conflicts increases when more collaboration-related features are added to the app and data is being used concurrently. So, it is always good to select a database that handles data conflicts and concurrency and shares the conflict handling policies on the website or at least on repository pages.


Top Databases for React Native in 2022




Realm is an object-oriented database that enables the creation of real-time and offline applications that run on both- wearable devices as well as smartphones. It is one of the top React Native databases amongst all the available ones. This database is highly preferred when the end goal of the project is building high-performance apps that can deal with a huge data flow. The database benefits both platforms- iOS and Android. It doesn’t depend on key-value stores as it has its own database engine. Realm allows the React Native app developers to frequently undergo tables, mapping classes, fields, foreign keys, etc.


Key Advantages of Realm:

  • Makes use of multiple encryption standards to ensure good security for diverse mobile platforms
  • Realm Synchronization service works locally in the background for recording user interactions and service requests and sends the data to the server after the device goes online.
  • Redux offline can be used to fulfill offline-first architecture requirements.



For React Native development, Firebase supports real-time NoSQL DB. This database is known for its offline data modifications and data synchronization capabilities. Besides, it can handle M (model) and C (controller) of the MVC that is needed while building React Native applications.


Key Advantages of Firebase:


  • This database allows real-time data syncing for all the clients simultaneously.
  • Firebase offers a cross-platform API that can be easily set up with minimum effort.
  • Firebase database can be directly accessed with a mobile device and so, the application servers are not needed.
  • Firebase supports the creation of real-time apps with offline persistence capabilities.



SQLite is a relational database management system developed for offering local storage to React Native applications. ‘Lite’ in SQLite depicts the lightweight nature of this database. Also, this database is very easy to set up. It can be directly integrated with mobile applications for accessing the database. For data encryption, SQLite can be used with an extension called SQLite Encryption Extension (SEE).


Key Advantages of SQLite:


  • This database can support offline persistence, simply by using a react-native-SQLite-storage plugin for data management within the mobile app.
  • SQLite is ACID-compliant and employs most of the SQL standards with just a few omissions. It comes with a file-based library architecture and some tools for easily and efficiently handling all data types.



This is a JavaScript database developed using a storage mechanism and CouchDB protocols. It stores the data in JSON format. This open-source database enables the React Native developers to read, create, delete, update, and query the objects using a singleJS API. Furthermore, PouchDB is compatible with MongoDB, CouchDB, PostgreSQL, and MySQL.


Key Advantages of PouchDB:


  • It allows data syncing using a supported server for running the apps online as well as offline.
  • Ensures speedier execution of queries.
  • Also, as PouchDB remains inside a browser, it is not necessary to run queries over the network resulting in faster execution of queries.



This is an open-source, lightweight, and fast database used for React Native-based application development for both- Android and iOS. It is developed with a robust server-side language-Golang, created by Google. Vasern’s API can also be utilized for syncing across app clients, local storage, and for cloud storage.


Key Advantages of Vasern:


  • Vasern ensures good performance of apps and speedier operations
  • Provides end-to-end database syncing
  • Support basic data types like string, double, int, double, reference, DateTime, etc.
  • Provides support to languages that use UTF – 8 coding.

Watermelon DB


This database is built on top of SQLite. It can scale a myriad number of records without impacting the application speed. This database is perfectly optimized for complex apps built with React Native that ensures real-world performance.


Key Advantages of Watermelon DB:


  • It is a fast, multi-threaded, relational, and highly cached database.
  • It supports an offline first system for syncing with your own backend.
  • It allows static typing with flow



This is a high-performing backend and allows the developers to handle data in several ways. It comes with an API that is compatible with numerous languages and several platforms like Android and iOS.


Key Advantages of BerkeleyDB:


  • Simple to use
  • Provides support for industrial-strength transactions
  • Ensures concurrent access for multiple users



This is a local storage database and comes in-built with React Native. It enables developers to persist data between reboots of the apps. It acts as an outstanding solution for saving the data that the app required, even when the app is being closed by the users.


Concluding Views:


Apart from the local databases mentioned here, there are several other databases available for the React Native app developers to utilize in their projects. But, the choice of a database ultimately depends on the project requirement, its scope, and end goals. For instance, Firebase suits perfectly when one has to develop real-time apps. Realm is great for almost every possible requirement, but comparatively, SQLite doesn’t provide the same level of performance, scalability, and security. Rather SQLite is good to go with when one needs to leverage the abilities of a relational database. So, the one that suits your requirements is the best choice for you.

What are APIs, how do they work, and why are they Beneficial to Developers and Businesses?

We’re living in an API-centric world. Many of our daily activities revolve around APIs, and most of us are not even aware of it!


Have you ever wondered how the following actions are executed?


You can instantly browse information on the current weather conditions as well as the weather forecast using platforms like Apple’s weather app, Google search, or smart home devices.


The travel booking websites aggregate numerous destinations and flights right away for displaying the cheapest option to you.


You can log in to certain websites and mobile apps using the profile login details of your Google/Facebook/Twitter account.


You can play Spotify while using the Uber app.


Well, the common component responsible for all these prompt and useful actions is an API! APIs connect two distanced entities and enable them to communicate with each other in a standardized format. APIs reduce a considerable amount of time and effort to securely exchange data. For instance, weather booking sites collect information from a third party via APIs, and the weather data is sent to them in a manner that can be easily reformatted. Travel booking sites use third-party APIs for gathering information on the availability of flights and hotels directly from the providers. A website can leverage the API of popular services like Google or Facebook to authenticate a user so that users do not have to bear the hassles of creating a new profile for every website service.


Likewise, Uber uses an API to connect with Spotify.


So, what is an API, how does it work, and why is it important? This post answers them all! Read along to gain comprehensive insights on an API, its functioning, and its importance from the perspective of developers and businesses.


The Basic Principle of an API

An Application Programming Interface, commonly known as an API, is a software intermediary that enables computers/computer programs to communicate with one another. In other words, an API contains a set of functions using which apps can access data and can interact with various OSs, external software components, or microservices.

When one uses an app using a smartphone device, the app sends data to the server using the internet. The server retrieves this data, then interprets the data, carries on the required actions, and finally sends the data back to the user’s mobile device. Now, the app interprets this data and displays the information requested by the user in a readable format. All the aforementioned actions are made possible by an API.


How does an API function?

Technically, an API comprises a bunch of defined rules that instruct how software apps or computers will communicate amongst each other. An API works as the intermediary layer between an app and the web server; it processes the data transfer that takes place between the systems.


Steps on how an API works:


Step # 1


A request is placed by the user – the client app initiates an API call for retrieving information. Then the request gets processed from the app to the web server, through the URI (Uniform Resource Identifier) of the API.


Step # 2


Once a valid request is received, the API makes a call to the web server or the external program.


Step # 3


A response is then sent by the server/program to the API. This response contains the requested information.


Step # 4

Now, the API transfers this data to the app that had initiated the request for obtaining the information.


Here, the data transfer varies based on the web service used.



When you search flights online, you need to choose from different options available like departure/return dates, one-way/round trip, names of the departure & destination city, the type of seats, the number of passengers, and so on. Through these actions, you are actually interacting with the website of a particular airline and accessing their database to check the seat availability and flight fare on the desired dates.


Now, let’s discuss an instance when you are not using any specific airline’s site for directly obtaining the information; but using an online travel service to check out the deals offered by various airlines and choose the best available option. Travel services like Expedia, MakeMyTrip, Kayak, etc. aggregate information from the databases of several airlines by interacting with an airline’s API. The third-party provider will allow this interface to execute actions like acquiring information from airline databases, booking seats for passengers, etc. After receiving the request for such actions, the API will collect the airline’s response to this request and deliver the response back to the aggregator. And, thereafter the aggregator will display the updated and relevant information to the passenger.


Tips on API Development

A sound API comes with clear and concise commands that can be reused by programmers. While designing APIs, developers need to create endpoints within an API. An endpoint is an URL performing a specific kind of function. Endpoint provides a path for other fellow developers to follow and this way, the API development process is smoother, ruling out chances of confusion and guesswork.


The Modern API Development: Characteristic Traits

Today, APIs are considered more as products than codes and are created for specific sets of users like software developers. And, like any other software end-product, APIs come with their own SDLCs (software development lifecycles) – designing, development, testing, managing, and versioning. A modern API adheres to HTTPS and REST standards so that they are understood properly, can be easily accessed, and are developer-friendly and secured.


APIs ensures safe data transfer between different platforms. The endpoint of the API decouples the consuming app from the service provider’s infrastructure, API calls include authorization credentials for minimizing the threat of attacks on the server, and an API gateway is empowered to limit access for ruling out security risks. Besides, during the exchange of data, extra layers of security are employed in the form of cookies, HTTP headers, query string parameters, etc. Navigate this link to learn more about the best practices for ensuring API security.


A good API usually contains different formats as various apps communicate in different languages including CSV, XML, and JSON. Furthermore, comprehensive documentation stating an API’s usage is present to make it DevOps-friendly. Also, good APIs are supported and backed by dynamic developer communities for extending help to the ones who get stuck.


Types of APIs


Public API

Public APIs are meant to be shared with the outer world such that an external mobile app development company or developer can leverage the capabilities of these APIs for building apps. Certain firms provide semi-public access to their APIs – no public documentation is available; developers/development companies need to submit their

apps for approval.


Private API

These APIs are internal ones created for specific user bases and audiences. Such APIs are used within an enterprise for enhancing collaboration and facilitating communication amongst employees. These APIs can be used by those employees who are granted access.


Why are APIs important for Developers?



No Need to Reinvent the Wheel

Ready-to-use APIs are available for all OSs including iOS, Android, and Windows to carry out most standard developmental tasks. As such, things become easier for developers; they do not have to reinvent the wheel and waste their time and efforts in API development.


For example, if developers are building an iOS application and need to embed a web browser for displaying pages on browser inside the app; they don’t have to program a web browser from scratch. All they need to do is utilize the WKWebView API for embedding a WebKit (Safari) browser object within the app. Similarly, instead of creating a camera interface separately for an app, the camera API is used for embedding the in-built iPhone camera into the application. If developers intend to provide the facility of fingerprint authentication support for an Android app, they need not test every fingerprint sensor of different Android manufacturers. They just need to use a ready-made API!


With such useful APIs, developers can acquire quite a lot of data, services, and resources while building apps. This reduces the time-to-market.


More Scope for Innovation

After integrating APIs into a system, you get an application layer for distributing pieces of information smoothly into other systems. This way, new services can be introduced to new audiences as per their ever-changing desires & needs - developers can utilize APIs for creating personalized services/features for them.


Increased Efficiency

API access enables businesses to publish the app content very quickly as the system automatically publishes content and makes it available for all channels. This way, the content reaches a wide range of audiences effortlessly and in much lesser time and cost as compared to traditional marketing practices.


Effortless Adaption

Software systems of a firm need to be updated within time and the presence of a custom API speeds up this process. Furthermore, data migration becomes easier and the information can be reviewed in a better way.


Why are APIs important for Businesses?


Workflow Automation

API integration has helped several enterprises to automate workflows and enhance workplace collaboration. The absence of APIs would have created connectivity woes and informational silos, adversely affecting performance and productivity.


Facilitates B2B Dataflows

APIs are essential for running data-driven businesses. API usage enables businesses to integrate data flows with their partner’s systems or customers. They also increase the flexibility of traditional data exchange methods like EDI and MFT.


Improved Success Rates

Several businesses maximized efficiency as well as revenue generation through joining forces with other businesses. For example, Uber didn’t waste time, money, and efforts in creating their own services like mapping, communication, or payment gateway. Instead, they utilized the best available services and integrated these services into their app via APIs. And, their success rate and profits are evident.



APIs are omnipresent, empowering our daily activities from behind the scenes, without being noticed. And, most importantly, they are an integral part of today’s economy. APIs not only enable the sharing of crucial data, but also makes it possible to utilize practical business functionality between individuals, apps, and devices.

Prominent Blockchain Programming Languages to consider while building Blockchain Apps!


Blockchain has become a buzzword in today’s tech world. This technology has successfully resolved the traditional roadblocks existent in certain industrial domains by decentralizing dataand opening up new avenues of security and transparency.


Blockchain records digital information ina manner that the information can be recorded and distributed, but not altered. Hence, Blockchain is used to form immutable ledgers and records or transactions that cannot be hacked, modified, or destroyed. Blockchain applications are employed for demanding tasks like the exchange of cryptocurrencies, the secure sharing of medical data, voting mechanism, NFT marketplaces, making/receiving cross-border payments, monitoring supply chain/logistics, and many more.


However, developing such solutions is not an easy task, and businesses planning to adopt Blockchain systems must be aware of the ins and outs of Blockchain development. One of the crucial considerations for creating Blockchain solutions is the programming language stack chosen for development. And, needless to say, the programming language should be chosen as per the project requirements. This post explores the offerings of the top Blockchain programming languages with examples of use cases. The write-up will provide a clear idea and help you to pick the most suitable language stack for your upcoming Blockchain project.


Blockchain Functioning: In a Nutshell


The Blockchain system comprises a digital ledger of transactions. Each block within the chain contains a certain number of transactions and whenever a new transaction takes place on the blockchain network, the transaction record is added to each participant’s ledger. This decentralized database is called DLT (Distributed Ledger Technology) and is managed by multiple participants.


Top Blockchain Programming Languages





Solidity was created by the Ethereum team in 2014 for writing Ethereum-based smart contracts, to enhance the usability of Blockchain solutions. With Solidity, developers were able to write a high-level code that is smart-contract oriented and that could be translated into the usable lower-level languages prevalent at that time.The language resembles the ECMAScript syntax but contains features such as static typing, variadic return types, and so on. And hence, it is one of the mostpreferred programming languages used for Blockchain projects and recommended by mostBlockchain app developers around the world.


This statically typed Blockchain language offers a stable and flexible coding pattern for smart contracts and provides an accurate as well as a safe medium where different sources can frame smart contracts between parties. Moreover, it is a flexible and user-friendly language that comes with ABI (Application Binary Interface) that provides several type-safe functions. Developers can effortlessly acquire the necessary skills needed to use Solidity, whether they are experienced ones or simply beginners.


Blockchain Project Use Cases: Ethereum, Chainlink, Sushiswap, and Compound Protocol.




This object-oriented language is one of the key Blockchain programming languages. C++ was created to code the decentralized cryptocurrency system and developers employed it to code bitcoins. But today, it suits the purpose of other Blockchain-based projectsand has been used for storing transaction information in cryptocurrencies like Ripple’s XRP Ledger, Ethereum’s smart contracts, etc.


C++ is easy to use and flexible; and comes with abilities like advanced multi-threading, primitive control over memory, and an efficient CPU management capability. It enables one to isolate the code for various data structures and allows you to move semantics so that data can be copied effectively. C++ users can control the code as desired – they can choose between providing full access to the code or allowing access to only certain aspects as per the need. With C++, one can easily manipulate blocks and chains, and so, is an ideal pick for scenarios where one needs to fully control their system resources.


Blockchain Project Use Cases:Monero, Ripple, Stellar, EOS, Litecoin.




Python is one of the most popular programming languages used for architecting Blockchain applications, crypto exchange, and smart contracts. It is a robust, versatile, and object-oriented programming language that comes with open-source support and also, several frameworks and libraries such as Numba that accelerate the development without affecting the performance or security. Python dynamically supports OOP, and hence, facilitates crafting solutions in Blockchain as well as in Machine Learning and Artificial Intelligence. Using this language, one can easily detect errors and debug those errors.


Python is particularly helpful for newbie developers working on Blockchain projects as this language facilitates building prototypes quickly without having to write lengthy codes and the developers have the option of selecting from a wide range of plugins, libraries, and online resources.

Python, being an interpreted language creates roadblocks when complicated cryptographic operations are involved, but this problem can be resolved by the proficiency of experienced Blockchain app developers.


Blockchain Project Use Cases: Steemit, Ethereum, Hyperledger Fabric, NEO, etc.




GoLang, a statically typed, compiled and multi-threaded language created by Google, is one of the most popular Blockchain programming languages in the NFT marketplace. The language integrates the best of both worlds – the ease of developing the code and the effectiveness of compiled language. It combines the features of Java, Python, and C++ and is being used by the Hyperledger Fabric platform currently. It is user-friendly, fast, flexible, and scalable.


Using GoLang, one can run several processes simultaneously, and therefore, it is can effectively handle several parts of blockchain simultaneously. GoLang is not only speedy but also offers accessible maintenance features and so, it’s an ideal pick when a decentralized app is being distributed on Ethereum’s network. However, it comes with a difficult learning curve but will be simple for C++ developers.


Blockchain Project Use Cases: Ethereum, Loom Network, Hyperledger Fabric, GoChain, and Dero.




Java is an object-oriented programming language that follows a “write once and follow everywhere” approach and so, enables one to write codes that are highly portable. With the Java Virtual Machine (JVM), developers can run their codes on any system or platform. And, as the universal JVM is used for execution, Java programs need not depend on a system-specific architecture. This portability of Java facilitates the creation of easy-going and immutable blockchains. Furthermore, Java comes with an abundant API (Application Programming Interface) that contains several Java classes, interfaces, packages, etc. This property helps in building apps without any need to know their internal implementations.


Java offers a simple and extensible plugin architecture that helps to create a flexible Blockchain solution. Java has a huge and dynamic community that provides prompt and effective solutions to developers whenever they encounter any issue.


Blockchain Project Use Cases: IOTA, NEO, NEM, Ethereum, Fabric, and Hyperledger.




C# is an open-source programming language coined by Microsoft and enjoys humongous popularity worldwide. It employs easy Object-Oriented and Extensible Markup methods, without the developer’s help. Its rich library class simplifies the use of menu functions and implements them for coding. The assembly feature eases out handling the issue of version control. With C#, open-source developers can effortlessly write codes that are highly portable and run across several OS like Mac, Linux, Android, and Windows.


Blockchain Project Use Cases: IOTA, NEO, Blockchain as a Service, and Stratis.




Rholang is employed for creating smart contracts and high-grade Blockchain projects. It follows a functional approach – at first, it examines the application through several functions and thereafter, solves them as per the sequence. It is secure, reliable, easytouse, and speedy.


LLL (Low-Level-Lisp-like language)


Low-Level-Lisp-like language, commonly known as LLL, is a low-level programming language. LLL happens to be quite easy-going and minimalistic, it’s just a small-sized wrapper directly placed over the EVM coding. This is one of the original Ethereum programming languages used for smart contracts. It offers a different programming discipline and point of view as compared to the universal Solidity language.


To make it compatible with EVM programming, the Lisp-like code contains a thin layer of parentheses. So, the LLL users enjoy high-end programming support while accessing various lower-level sources of power as well as memory locations. Moreover, this language enables programmers to develop effective contracts that are smaller in size as compared to the ones created using higher-level languages.




This high-level Blockchain programming language was designed for smart contracts and it caters to professional programmers as well as open-source developers. This language is relatively new and reduces the low-level understanding and complicated functionality of the Bitcoin Script.


Simplicity helps Blockchain app developers to enhance productivity and avoid distractions. It hides low-level components from engineers and developers, resulting in a rapid development speed.




This popular programming language works for Blockchain development as well because of Node.js, a runtime environment of JavaScript. The language helps developers to handle asynchronous code which is the fundamental prerequisite in the Blockchain environment. Moreover, it enables asynchronous parallel programming due to which the Blockchain program can complete more than one action simultaneously. 




This Blockchain programming language is derived from Python3, although it doesn’t contain all the Python features in it. It was designed as an alternative for the language Solidity and is primarily employed in EVM (Ethereum Virtual Machine). However, Vyper’s control structures are different fromthe ones in Solidity and it handles security issues differently as well. Vyper’s control structure is distinct and contains features such as modifiers, recursive calling, infinite loops, etc.




Obsidian is one of the newer Blockchain programming languages. It presently functions on the Hyperledger Fabric platform and the Ethereum Blockchain platform.


Most blockchain programs are organized around a machine having a high-level state and Obsidian’s state-oriented programming helps one to explicitly declare and transition amongst states. Obsidian builds a flowchart-like sequence that helps one to view contracts through different stages. The states and transitions within the states have to be mentioned while coding.


Obsidian offers a linear type system that simplifies the process ofimplementing a belt to suspenders. The compiler can make full use of the types for avoiding bug issues or typo-based errors.


End Note
