Render HTML in React Native
React NativeReact Native Problem Overview
In my React Native app, I am pulling in JSON data that has raw HTML elements like this: <p>This is some text. Let’s figure out...</p>
I've added the data to a view in my app like this:
<Text>{this.props.content}</Text>
The problem is that the HTML comes out raw, it does not render like it would in a browser. Is there a way to get my JSON data to look like it would in a browser, inside my app view?

Edit Jan 2021: The React Native docs currently recommend React Native WebView:
<WebView
originWhitelist={['*']}
source={{ html: '<p>Here I am</p>' }}
/>
https://github.com/react-native-webview/react-native-webview
If you don't want to embed a WebView
, there are also third party libraries to render HTML into native views:
Edit March 2017: the html
prop has been deprecated. Use source
instead:
<WebView source={{html: '<p>Here I am</p>'}} />
https://facebook.github.io/react-native/docs/webview.html#html
Thanks to Justin for pointing this out.
Edit Feb 2017: the PR was accepted a while back, so to render HTML in React Native, simply:
<WebView html={'<p>Here I am</p>'} />
Original Answer:
I don't think this is currently possible. The behavior you're seeing is expected, since the Text component only outputs... well, text. You need another component that outputs HTML - and that's the WebView.
Unfortunately right now there's no way of just directly setting the HTML on this component:
https://github.com/facebook/react-native/issues/506
However I've just created this PR which implements a basic version of this feature so hopefully it'll land in some form soonish.

I found this component. https://github.com/jsdf/react-native-htmlview
This component takes HTML content and renders it as native views, with customisable style and handling of links, etc.
Solution 3 - React Native
A pure JavaScript react-native component that renders your HTML into 100% native views. It's made to be extremely customizable and easy to use and aims at being able to render anything you throw at it.
Using this component will improve your application memory footprint and performance when compared to embedded WebViews
.
Install
npm install react-native-render-html --save or yarn add react-native-render-html
Basic usage
import React from "react";
import { ScrollView, useWindowDimensions } from "react-native";
import RenderHTML from "react-native-render-html";
const html = `
<h1>This HTML snippet is now rendered with native components !</h1>
<h2>Enjoy a webview-free and blazing fast application</h2>
<img src="https://i.imgur.com/dHLmxfO.jpg?2" />
<em style="textAlign: center;">Look at how happy this native cat is</em>
`;
export default function App() {
// Allow images to scale to available width
// with contentWidth prop.
const { width } = useWindowDimensions();
return (
<ScrollView style={{ flex: 1 }}>
<RenderHTML contentWidth={width} source={{ html }} />
</ScrollView>
);
}
You may customize the style of elements via class names, tags, and you can even register custom renders for tags. More info on the official website.

i uses Js function replace simply.
<Text>{item.excerpt.rendered.replace(/<\/?[^>]+(>|$)/g, "")}</Text>

React Native has updated the WebView component to allow for direct html rendering. Here's an example that works for me
var htmlCode = "<b>I am rendered in a <i>WebView</i></b>";
<WebView
ref={'webview'}
automaticallyAdjustContentInsets={false}
style={styles.webView}
html={htmlCode} />
Solution 6 - React Native
<WebView ref={'webview'} automaticallyAdjustContentInsets={false} source={require('../Assets/aboutus.html')} />
This worked for me :) I have html text aboutus file.
Solution 7 - React Native
import HTML from "react-native-render-html";
var htmlCode = "<b>I am <i>Italic</i></b>";
<HTML source={{html: htmlCode}}/>
Solution 8 - React Native
The WebView
component was not rendering for me HTML snippets, like
<b>hello</b>, world!
But if I would enclose the HTML snippet in a document, like the example below, then it did actually render the document:
<View style={styles.accContent}>
<WebView source={{html: `<!DOCTYPE html><html><body style="font-size: 3rem">${data.content}</body></html>`}} />
</View>
