Journey From ReactJS to React Native: Beginner’s Guide

I was eager to create my first React-Native app because I’m a ReactJS developer.

I’ve been working on creating a cross-platform React Native app that provides details about RC.

This is a massive essay detailing what I’ve learnt about React-Native in the past month as a junior developer because the app will shortly be released.

I hit wall after wall since I had never worked with React-Native before until I finally understood how it differed from ReactJS. In addition, many design patterns are just simple React.

I’ve compiled a summary of the challenges I faced as a developer this year as I transitioned from ReactJS to React-Native. I hope this might assist others just starting out on their journey towards mobile app development.

The Difference Between Reactjs and React Native

Here is the core difference between Reactjs and React Native

React Native is a framework for building cross platform applications, whereas Reactjs is a JavaScript library.

React is an open-source JS library for building the UIs for web applications; besides, React Native is used to build rich mobile UI from declarative components using JavaScript.

React JS Utilises Virtual DOM While React Native Uses Native APIs

Apps don’t have a browser window or DOM.

Although it may seem apparent, if you hadn’t considered it previously, it will significantly alter the npm/yarn components that you may use in your app. There is no DOM in React Native. As a result, any component created in a manner that necessitates a DOM will not function at all in React-Native.

ReactJS

makes use of the virtual DOM to improve user experience. Due to the size of today’s DOM trees, the DOM creation takes time. However, React.js accelerates this process by making use of a virtual DOM. In order to implement changes to one component without affecting the other components of the user interface, React.js makes use of an abstract duplicate of the Document Object Model. This is what makes React.js so great at generating changes quickly and producing dynamic user interfaces.

React Native 

went one step further with this. It renders reusable UI components that may be used on both iOS and Android devices by utilising native APIs. In reality, it uses Objective-C APIs to create iOS components and Java APIs to render Android components. The remaining code is then written using JavaScript, customising the programme for each platform.

While React Native’s code may be integrated with any Existing App, React.js Combines Technologies

React Native does not use HTML or CSS, but React.js does. React Native implies <text> and <view> whereas React.js utilises <p> and <div>. As an illustration, consider the following:

For ReactJs

function MyApp() {
  const element = (
<div>
  <p>Hello, world!</p>

</div>
   );
  ReactDOM.render(element, document.getElementById('root'));
}

setInterval(tick, 1000);

For React Native

import React, { Component } from 'react';
import { Text, View } from 'react-native';

export default class HelloWorldApp extends Component {
render() {
return (
<View>
<Text>Hello world!</Text>
</View>
);
}
}

Navigation – A Different Approach for Reactjs and React Native

Although they each take a different approach from this viewpoint, the results are very close. Reactjs web apps use React-router but React Native uses a whole other package called Navigator for this purpose.

You need to be aware of the react-router-library, which provides navigation on click events, if you’re creating an application using React.Js. Use the useHistory hook in the framework to gain access to the history instance when React Router v5 was released.

If you hadn’t thought of it before, even though it might seem obvious, it will substantially change the npm/yarn components that you might utilise in your project. In React Native, there is no DOM. Therefore, any component made in a way that requires a DOM won’t work at all with React-Native.

Favourable to Search Engines

ReactJs

You must take SEO into consideration while you create your React.js application. React JS technology’s main objective is to provide a user interface that is simple to use and dynamically changes based on human input.

In reality, though, the Google bot is not a person. Therefore, in order for the Google bot to find our app, we must appropriately index our web page. 

React JS provides a number of tools and packages that may help you optimise your project for SEO.

React Native

React Native has nothing to do with SEO when it comes to our consideration. How we (react native developers) create native UIs is up to us.

Which of React or React Native is Better to Learn?

You should now have a better understanding of their siblings, ReactJS to React Native. As far as the platforms for the finished products go, they differ, but when it comes to the React Native development process, they are comparable.

Actually, learning another framework will be simpler if you master the React or React Native frameworks. However, you need to be familiar with React to create a React Native application. But things don’t stop there! More native apps need to be understood in depth because React Native only provides a limited amount of support for them.
