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

I'm trying to use a custom font on my vue native app, but dontt find how to do this. I've tried use #font-face.enter image description here
i found something like Font.loadAsync from react native, but i don't know how to use this
I been using expo documentation, perhaps this can leads you to a solution
Edit:
Well after installing the given font package, I imported expo-font in my app.vue file then I loaded inside the google font package and that's all
//App.vue
import * as Font from "expo-font";
Font.loadAsync({
VT323_Regular: require("./node_modules/#expo-google-fonts/vt323/VT323_400Regular.ttf"),
});
//export default { ...
.myText {
font-family: VT323_Regular;
}
<template>
<view class="container">
<text class="myText">ABCDEF</text>
</view>
</template>
I've created a simple html page and loading it into WebView :
const OurStoryHTML = require ('./test.html');
import { WebView } from "react-native-webview";
<WebView
source={OurStoryHTML}
originWhitelist={["*"]}
/>
My webpage contains the following tag:
<script async="async" src='http://www.youvisit.com/tour/Embed/js2'></script>
However, the script seems not to be loading in react-native-webview but works fine in the browser. Any workaround for this?
You must put double curly braces after source prop in WebView
source={{OurStoryHTML}}
Is it possible to add Video component into the react-native-snap-carousel? I want to try to create a carousel similar to Instagram's swipe
I was able to get swiping to work, but when I tried to add the video component from expo, it didn't show up.
const _renderItem = ({item, index}) => {
return (
<View>
<Video uri={item.uri}/>
<Text>{index} What are we trying to accomplish here {item.uri}</Text>
<ComponentVideo uri={item.uri} />
</View>
);
}
<ComponentVideo /> is another component I created, works normally. <Video /> is a component from expo that's inside ComponentVideo. I just brought it out to see if it works.
Thoughts?
Perhaps there's another package I should check out?
Is there any package that would allow me to display SVG image loaded from external URL?
I've tried to use react-native-svg-image / react-native-svg-uri and their forks but none of those are working correctly - is there any non dead package for react-native that would do the job?
This is the sample error being thrown by svg-img-uri
<SvgUri width="24" height="24" source={{ uri: 'https://cdnjs.cloudflare.com/ajax/libs/flag-icon-css/3.3.0/flags/1x1/ad.svg' }} />
Text strings must be rendered within a <Text> component.
This error is located at:
in RNSVGDefs (at Defs.js:8)
react-native-svg now supports display svg from online uri
import { SvgUri } from 'react-native-svg';
export default () => (
<SvgUri
width="100%"
height="100%"
uri="http://demo.com/assets/your/image.svg"
/>
);
Reference https://github.com/react-native-svg/react-native-svg#use-with-content-loaded-from-uri
The url doesnt' have any quotes around it. That might be the problem
<SvgUri
width="24"
height="24"
source={{ uri: 'https://cdnjs.cloudflare.com/ajax/libs/flag-icon-css/3.3.0/flags/1x1/ad.svg'}} />
This Github issue might help you.
If you still do not succeed, you can still convert your SVG file to a React Native Component using https://www.smooth-code.com/open-source/svgr/playground/ (don't forget to toggle React-native in the left panel)

How to correctly pass video into Shoutem HTML Component?
Shoutem's video component does what you're trying to do, you could simply use it instead.
<Video
source={{ uri: 'https://www.youtube.com/watch?v=myvideo' }}
poster={'https://mypic.png'}
height={200}
width={300}
/>
