Seamless HTML Rendering in React Native: A Comprehensive Guide
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-htmlHow 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:
- HTML markup is parsed into the DOM
- The Transient Render Tree is assembled based on input
- 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:
import React from 'eact';
import { View, Text } from 'eact-native';
import HTML from 'eact-native-render-html';
const html = '<div><p>Hello World!</p></div>';
const App = () => {
return (
<View>
<HTML html={html} />
</View>
);
};
Alternative to react-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:
import React from 'eact';
import { View, Text } from 'eact-native';
import WebView from 'eact-native-webview';
const App = () => {
return (
<View>
<WebView source={{ html: '<html><body><p>Hello World!</p></body></html>' }} />
</View>
);
};
