In the world of mobile app development, we’re always looking for shorter development cycles, a single code base, a centralized development team, and better app performance. With two operating systems dominating the landscape, you are often faced with a wide range of options such as will the apps provide a better user experience? is it possible the apps that are faster to develop and run on more platforms and devices? Should your team look at only developing with web technologies? What about some of the hybrid solutions out there? These are among the many questions that arise when deliberating which path is best for your business.

YES! we have the answer which resembles many of the solutions

React Native Is the Future of Hybrid App Development

REACT NATIVE helps you create real and exciting mobile apps with the help of JavaScript only, which is supportable for both android and iOS platforms. Just code once, and the REACT Native components are available for both iOS and Android platforms which helps to save development time.

What is Native Apps And Why Hybrid?

A native mobile app is an application that is developed for smart devices such as smartphones, tablets, and gadgets coded in a specific programming language: Objective C/Swift for iOS and Java/Kotlin for Android operating systems.

But developing this type of applications usually requires more financial, human and time resources just because two separate codebases are developed for two different platforms in two different languages by two different teams of developers. So, we, with that, let’s explore the world of native-like hybrid mobile application development.

What is react native and react?

React Native is a framework for building native applications using JavaScript.It compiles native app components, which makes it possible for you to build native mobile applications

React often referred to as ReactJS is a JavaScript library responsible for building a hierarchy of UI components or in other words, responsible for the rendering of UI components. It provides support for both frontend and server-side

In React JS, React is the base abstraction of React DOM for the web platform. while with React Native, React is still the base abstraction but it renders the native component. So the syntax and workflow remain similar, but the components are different

Ionic or react?

In order to accomplish the goal of building for a specific platform, each of these technologies has different philosophies to which they adhere. We can divide these beliefs into two major categories: Hybrid-Native and Hybrid-Web. Hybrid we mobile application renders the Web UI components such as div, span, etc while Hybrid native compiles the exact native components which are imported already

React native working

1) At the first start of the app, the main thread starts execution and starts loading JS bundles.

2) When JavaScript code has been loaded successfully, the main thread sends it to another JS thread because when JS does some heavy calculations stuff the thread for a while, the UI thread will not suffer at all any time.

3) When React start rendering Reconciler starts “diffing”, and when it generates a new virtual DOM(layout) it sends changes to another thread(Shadow thread).

4) Shadow thread calculates layout and then sends layout parameters/objects to the main(UI) thread. ( Here you may wonder why we call it “shadow”? It’s because it generates shadow nodes )

5) Since only the main thread is able to render something on the screen, shadow thread should send the generated layout to the main thread, and only then UI renders.

we can separate React Native into 3 parts :

1) React Native – Native side

2) React Native – JS side

3) React Native – Bridge

A piece of code

Here we can see the react itself renders the native components. and the styleSheet is an object which combines all the style property, not like actual CSS. We can find a lot more convenient ways to design things .

React Native provides a number of built-in components. You will find a full list of components and APIs on the sidebar to the left. If you’re not sure where to get started, take a look at the following categories:

How to run an Android App?

  1. Install Dependencies like NODE, Python v 8*, JDK 8*, etc.
  2. Install the Android studio. make sure the Android SDK and virtual device are installed
  3. Create react native Project using NPX npx react-native init AwesomeProject
  4. Finally cd AwesomeProject npx react-native run-android it will run the app in the emulator

Another way to run and publish your app is Expo, a framework and a platform for universal React applications. It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps from the same JavaScript/TypeScript codebase.

Why React native

  • Cross-Platform Compatibility- which means that your one component will work on both iOS and Android.
  • Shorter Development Cycles-React Native makes the process of developing mobile apps much faster(30% using open source components, Redux-state management tool)
  • Live Updates and CodePush-Developing native mobile applications with React Native has one very big advantage – Live Updates. Developers can push the updates to the user’s phone without having to go through the app store update cycle
  • React Native builds are alike Native Apps
  • Better Development Environment- nodejs
  • Huge community – 1m stars in Github
