Add Static Image Resources in Vue Native - react-native

I understand that in order to add static image resources in react native, the images have to be statically known. This is done by:
var icon = this.props.active
? require('./my-icon-active.png')
: require('./my-icon-inactive.png');
<Image source={icon} />;
In vue native, like in react native, using
<image
:source="{require('./my-icon.png')}"
/>
will not work since the static image isn't statically known.
How do I make the image statically known in Vue Native?


In Vue-Native you need to write it like this:
<image
:source="require('./my-icon.png')"
/>
Drop the {} between ""

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?

How to pass the parameter from react native webview to external javascript files function which is stored in xcode

How to pass the params from react native webview to external javascript function,
I have app.js file which is added in my react native project, and it contain some function like callfromapp(data), and i need to pass the parameter from react native webview to app.js function.
iam adding function injectJSFileFromWeb() inside webview.js iam giving the app.js file path but when it calls app.js file, iam getting error like document is not defined,
inside react native webview.js,
<WebView
ref={ref => (this.webview = ref)}
source={{ uri: 'example/index.html' }}
originWhitelist={["*"]}
domStorageEnabled={true}
startInLoadingState={true}
allowFileAccess={true}
javaScriptEnabled={true}
onLoad={()=>injectJSFileFromWeb()}
/>
injectJSFileFromWeb() {
//give the filename according to your need
var jsFileName = require('../../../ios/build/../example/app');
}

The WebView has attribute onMessage, which can receive messages from WebView. See example in official API documentation https://github.com/react-native-community/react-native-webview/blob/master/docs/Guide.md#the-windowreactnativewebviewpostmessage-method-and-onmessage-prop

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)

Reusable Button with image tag (React Native)

I want to turn this section of code into a reusable component so I don't have to write the same thing out 5 times.
<TouchableOpacity onPress={console.log('pressed')}>
<Image
source={require('../img/button_australia.png')}
/>
</TouchableOpacity>
The new component I made to mirror this is as follows:
import React from 'react';
import { Image, TouchableOpacity } from 'react-native';
const ImgButton = ({ onPress, img }) => {
return (
<TouchableOpacity onPress={onPress}>
<Image
source={require(img)}
/>
</TouchableOpacity>
);
};
export { ImgButton };
After importing this component ImgButton I call it with this block of code:
<ImgButton
onPress={console.log("pressed")}
img={'../img/button_australia.png'}
/>
I get the error: "Requiring unknown module '../img/button_australia.png'"
I assume I've gone wrong when passing the string down as a prop but from the examples I've looked I don't see what's wrong with what I've done. Thanks :)

As discussed in this react-native issue, it's not possible to require assets or javascript modules with dynamically generated names, e.g. variables.
This is because the React Native packager uses require (and import) statements to generate the module and asset bundles at compile-time, so the value of the variable is not known.
The simplest way is to just pass the image source to the component directly:
<ImgButton
onPress={console.log("pressed")}
img={require('../img/button_australia.png')}
/>

Render HTML in 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>
