Render HTML in React Native - react-native

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>

How to use custom fonts on Vue native?

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>

React Native: <script> tag not working in react-native-webview

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}}

How to use videos in react native snap carousel? Perhaps another better carousel package for react native?

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?

Displaying external SVG image from URL in react native

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}
/>
