how to convert your existing mobile app to react native quickly itechnolabs

It was the year 2015. The digital world was not doing as well as it is doing today. The community of web wizards were particularly distressed. There were many hassles in their way to technological advancement. But one hassle bothered them the most – they had to create different codes for different platforms for a single application. 

Life was devoid of any hope. But then something spectacular happened. The greatest of the great, Facebook, invented a cure for this problem of the web wizards. It was React Native – an open source framework that enabled the use of a single code for web, mobile, android, or iOS. 

The wizards readily converted their existing mobile apps to React Native. Some started creating new ones with it. With its Midas’ touch, React Native transformed the digital world forever, for good. To all the web wizards out there, who have not used React Native yet, what are you waiting for? Just try making an app with React Native or convert your existing mobile app to React Native. We are 100% percent sure that you are going to do so right after you finish reading this blog.

What is cross-platform development?

We are well aware that React native is the talking point right now. However, we can not understand it thoroughly if we skip discussing what cross-platform development is. 

Let’s assume you are a developer who has an advanced proficiency in Java language and refined experience in making apps for the android operating system. It is safe to say that you can easily build powerful android mobile applications

But if you were to build the same application for the iOS operating system, things won’t look as simple as they looked earlier. You will have to learn Swift or Objective-C, gain a working knowledge of the iOS operating system and then create another codebase for the same application in Swift or Objective-C. Ages will pass, surely. 

But do not worry. Here comes the ground-breaking concept of cross-platform development to your rescue. With the help of cross-platform development, you just have to write a single codebase in a programming language that is platform-agnostic. Platform-agnostic languages are the ones that are not specific to a single operating system, i.e. they are not native. JavaScript, Dart and C# are languages that are platform-agnostic. 

All you have to do is to write a code in one of these languages using the underlying structure of a cross-platform framework and boom! You have an application that runs smoothly and native-ly on multiple platforms without a single hitch. We can not think of anything even slightly superior than cross-platform development right now. 

What is React Native?

In very simple words, React Native is one of the very few cross-platform frameworks that offers an already-established set up to build cross-platform applications. It has been built using JavaScript programming language and JXL, a markup language. 

If you want to build a mobile application that runs effortlessly on android as well as iOS devices, React Native framework is the essential key. It is an open-sourced framework available on Github. Therefore, accessing it is not at all a hindrance.

You can use its Java Script library to fetch the already-written code to build and add UI to the framework. If you want, you can always access some external UI library, only if they are compatible with the React Native framework.

On a very fundamental level, React Native framework is a bridge framework. It creates a sleek bridge between the JavaScript code and the native code of the device. Doing so, it provides an authentic mobile experience to your users and enables them to smoothly use device APIs. 

The history of React Native framework

There is hardly any doubt that React Native framework is the present and the future of the mobile application development domain. Let us take a sneak-peek into the history of React native before we move ahead. 

  • It all began in the year 2011 when FaxJS came into existence
  • FaxJS was a mock-up for a sophisticated framework for web applications that Facebook was in desperate need of
  • In the very next year, FaxJS evolved into React Framework
  • In 2013, React became an open-sourced framework, i.e. anyone can use it and modify it to build their websites
  • In 2012, Facebook was determined to release a mobile application
  • Facebook tried using HTML5 for rendering mobile applications, but failed miserably
  • Doing so with the web-based framework posed many hurdles as mobiles and computers have very distinctive differences
  • With a highly talented team, Jordan Walke of Facebook came up with React Native in the year 2015
  • React Native became a framework for developing mobile applications and became open-sourced that very year
  • React Native has not looked back since then and is evolving year after year

How does React Native framework work?

If you want to get the basics of the working of React Native framework, you have to understand it in terms of domains. 

In React Native framework, there are two distinct domains – 

  • One domain is built of JavaScript threads
  • The other domain is built of native threads

Both the domains are written in distinct languages. First one is written in JavaScript. The native one is written in Java or Kotlin, if native operating system is Android, or Swift or Objective-C, if native operating system is iOS. 

The React Native framework is fundamentally a bridge through which information is exchanged between the two domains and tasks are accomplished on the mobile app. 

Therefore, converting your existing mobile app to React Native is a very easy task because of the bridge approach. 

What mobile apps have been developed using React Native framework?

  • Facebook 
  • Instagram
  • Shine
  • Skype
  • Pinterest
  • UberEats

The applications are one of the biggest hits in the mobile app development domain. They are the critical testimonies for one of the greatest inventions of developer-kind which is React Native framework. 

Are you ready now to convert your existing mobile apps to React Native framework?

How to convert your existing Android (Kotlin/Java) mobile app to React Native?

  1. Firstly, set up a directory structure for your React Native project and copy your existing android project to it 
  2. The next step is to install JavaScript dependencies to it
  3. You have to configure your dependencies and project setup 
  4. The next step in this conversion will be to enable the autolinking of native modules Autolinking allows your project to find the code and use it
  5. Get you internet permission ready and keep an eye on the configuration of other permissions too
  6. Enable the ClearText traffic which is disabled by default in android operating system
  7. Now, engage in code integration by following the steps given below
  • You have to build an index.js file
  • Now, simply add the React Native code
  • Obviously, seek permission for development error overlay
  • RenderRender JS component

8. Test your integration by running the server first and then the application.

What are the benefits of using React Native framework?

  • Many Platforms, One Solution
  • Intuitive User Interface (UI)
  • Huge Community –
  • Quick Reload –
  • Big Money Saver

Uncountable, if you ask us. Who would not want to convert their existing mobile apps to React Native framework? We doubt that there would be any. Only the name of React Native echoes in the air when we talk of mobile app development. The reason is not one but many, which we have listed below –

  • Many Platforms, One Solution –

Let’s just talk about the obvious reason first. With React Native framework, you only need a single codebase for your iOS as well as android devices. No need to squander time, money and developers into writing different codebases, when your mobile application can function well with one on different platforms. 

Wait, wait! If you have a web application also made using React Native framework, your development work for mobile is approximately ninety per cent already accomplished. Just sit back and relax!

  • Intuitive User Interface (UI) –

The React Native framework follows a component-based approach when creating UI for the application. What does this mean to you?

If you are currently leveraging React Native framework for building a mobile application, you are up for a fun ride. React Native framework lets you use React JavaScript library to build UI of your mobile application. The library comprises platform-agnostic components which you can use to design a responsive, native UI. 

The loading time shrinks as the user experience swells. With the component-based approach of the React JavaScript library, designing complex UI becomes a piece of cake for you.

  • Huge Community –

Suppose you are writing code for mobile app development. Suddenly, you stumble upon a glitch in the framework you are working on and you can not find a way to fix the glitch. You need help but you do not know anybody having an advanced knowledge of the programming language or the framework. What do you do?

If React Native is the framework you are using to build your mobile app, then there are thousands of developers you can turn to. React Native has a large support tribe. The tribe is always ready to help you out and build your application.

  • Quick Reload –

No, you need to rebuild your app after you made some changes to its code for the UI. Atleast, you do not have to if you are using React Native.

React Native quickly reloads the app and allows you to see changes as you make them. You save plenty of your man-hours and brain cells because of React Native’s quick reload option. Also, compiling becomes a ducksoup because React Native allows you to reload only those areas which you have modified.

  • Big Money Saver –

This point is really an extension of the first point and demanded a special mention. If you are building an app or converting an existing mobile app to React Native, you are an entrepreneur for sure. For an entrepreneur, money is a limited resource.

When you use React Native, you use one code for multiple platforms. You do not need a separate team of developers for a separate platform. There you save money! A lot of it. Time is also money for an entrepreneur. You get to spend less time and your application reaches the market early. The shorter Time to Market (TTM) is a big-win situation for you.

Do we need to say more? We bet that we do not. We are sure that you are persuaded enough to convert your existing mobile app to React Native or just start with a new one.
