Render HTML in React Native: A Step-by-Step Guide

Seamless HTML Rendering in React Native: A Comprehensive Guide

Are you looking to convert your website or web application into a mobile application using React Native? Or do you have static HTML code that you want to integrate into your React Native app? Look no further! This article will walk you through the process of rendering HTML directly in React Native using the react-native-render-html library.

Prerequisites and Setup

Before we dive in, make sure you have the following prerequisites:

• npm and Node.js installed on your device
• Basic understanding of React and React Native
• A React Native project set up (if not, create one using npx react-native init)

Using react-native-render-html to Render HTML

The react-native-render-html library is an open-source component with over 3,000 GitHub stars and 46 contributors. It takes your HTML and renders 100% native views in your iOS or Android apps. To use it, simply install the package using npm:

npm install react-native-render-html

How react-native-render-html Parses HTML

The library uses a data flow diagram to demonstrate how it parses HTML into React Native. Here’s a brief overview:

1. HTML markup is parsed into the DOM
2. The Transient Render Tree is assembled based on input
3. The TTree is rendered into Virtual DOM

For more information on how rendering works, refer to the library’s documentation.

Applying Styles to Elements

To style your HTML elements, you can use inline styles or pass custom styles using the tagsStyles attribute. For example:
“`jsx
import React from ‘react’;
import { View, Text } from ‘react-native’;
import HTML from ‘react-native-render-html’;

const html = ‘

Hello World!

‘;

const App = () => {
return (



);
};
“
**Alternative toreact-native-render-html`: React Native WebView**

Another option for rendering web components in React Native is React Native WebView. This modern cross-platform alternative has great support for embedding whole web apps to simple HTML files. Here’s an example:
“`jsx
import React from ‘react’;
import { View, Text } from ‘react-native’;
import WebView from ‘react-native-webview’;

const App = () => {
return (



);
};
“`
Conclusion

React Native is a popular choice for mobile app development, and rendering HTML directly in React Native can be a game-changer. With libraries like react-native-render-html and React Native WebView, you can seamlessly integrate your existing HTML code into your React Native app. Make sure to choose the library that fits your requirements, and happy coding!
