React Native Webview not loading any url (React native web view not working)

Question

I am trying to implement react native webview component in my application, but the web view is not loading any url its just showing the white page.

var React = require('react-native');
var{
 View,
 Text,
 StyleSheet,
 WebView
} = React;


module.exports = React.createClass({
 render: function(){
   return(
     <View style={styles.container}>
      <WebView source={{uri: 'https://m.facebook.com'}} style= {styles.webView}/>
     </View>
   );
 }
});

var styles = StyleSheet.create({
   container: {
     flex:1,
     backgroundColor:  '#ff00ff'
   },webView :{
     height: 320,
     width : 200
   }
});

Below is the screenshot of the output .

Answer 1

I had this issue. WebView would render when it was the only component returned, but not when nested in another View component.

For reasons I'm not entirely sure of the issue was resolved by setting a width property on the WebView component.

class App extends React.Component {
  render() {

    return (
      <View style={styles.container}>
        <WebView
          source={{uri: 'https://www.youtube.com/embed/MhkGQAoc7bc'}}
          style={styles.video}
        />
        <WebView
          source={{uri: 'https://www.youtube.com/embed/PGUMRVowdv8'}}
          style={styles.video}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'space-between',

  },
  video: {
    marginTop: 20,
    maxHeight: 200,
    width: 320,
    flex: 1
  }
});

Answer 2

I'm facing same issue. What I observed is that WebView doesn't work if it's nested. If component returns just WebView, then everything is fine.

Answer 3

Using the answers from other users, I was able to get my react native with webview working both inside a view and outside a view. My problem came down to two things. Being on the android emulator and behind a proxy, I just had to go to my browser (chrome) in the android emulator and sign in to the corporate proxy. Secondly, some sites work and others will not work. Whether the webview was nested or not inside of a View tag, some sites like cnn.com and slack.com etc will work fine, but no matter what settings I tried for google.com it wouldn't work (even though the proxy will definitely allow google.com) Lastly, when I rebuild my application and push to the emulator the new app, sometimes it took an inordinately long time to load any site. But once the site was loaded, the links are quick and responsive. So if you don't at first see something after a build, also be patient. Hope this helps someone else.

My final app.js

import React, { Component } from 'react';
import {
  Platform,
  StyleSheet,
  Text,
  View,
  Dimensions
} from 'react-native';

import { WebView } from 'react-native';

const deviceHeight = Dimensions.get('window').height;
const deviceWidth = Dimensions.get('window').width;

type Props = {};
export default class App extends Component<Props> {

  render() {
    return (
<View style={{flex:1}}>
  <WebView
   style={styles.webview}
   source={{uri: 'https://www.slack.com'}}
   javaScriptEnabled={true}
   domStorageEnabled={true}
   startInLoadingState={false}
   scalesPageToFit={true} />
</View>
    );
  }
}

const styles = StyleSheet.create({
  webview: {
    flex: 1,
    backgroundColor: 'yellow',
    width: deviceWidth,
    height: deviceHeight
  }
});

Answer 4

WebView works well on Android. However you need to enable javascript and dom storage for some web pages.

<WebView style={styles.webView}
    source={{uri: 'https://google.com/'}}
    javaScriptEnabled={true}
    domStorageEnabled={true}
    startInLoadingState={true}
    >
</WebView>

Answer 5

If you want the component to render the entire page, you need to wrap it with View that has flex: 1. The code below works for me:

<View style={{flex:1, alignItems: 'flex-end'}}>
  <WebView
   source={{uri: this.state.webContentLink}}
   startInLoadingState={true}
   scalesPageToFit={true} />
</View>

Answer 6

<View>
    <WebView
        source={{uri: this.props.link}}
        style={styles.webview}
        javaScriptEnabled={true}
        domStorageEnabled={true}
        startInLoadingState={true}
    />
</View>

and style as follows:

const React = require('react-native');

const { Dimensions } = React;

const deviceHeight = Dimensions.get('window').height;
const deviceWidth = Dimensions.get('window').width;

export default {
  webview: {
      width: deviceWidth,
      height: deviceHeight
  }
};

All this to deal with bad webview dimension, so just set a specific height and specific width too (deviceHeight and deviceWidth as the example above).

Answer 7

WebView is being moved to react-native-webview .

None of the other answers worked except this method:

npm install --save react-native-webview

Then use it as follows:

<View style={{ flex: 1, alignItems: 'flex-end' }}>
      <WebView
        source={{
          uri: 'https://www.yahoo.com',
        }}
        startInLoadingState={true}
        scalesPageToFit={true}
        style={{
          width: 320,
          height: 300,
        }}
      />
</View>

Answer 8

As of June 2020 (noting the date because React Native answers seem to become out-of-date quickly), the simplest solution to this appears to be:

import React from 'react'
import { View, StyleSheet } from 'react-native'
import { WebView } from 'react-native-webview'

export const ComponentWithWebView = () => {
  return (
    <View style={styles.view}>
      <WebView source = {{uri: 'https://www.google.com/'}} />
    </View>
  )
}

const styles = StyleSheet.create({
  view: {
    alignSelf: 'stretch',
    flex: 1,
  }
}

This results in a WebView filling the available space and being nested within a View. I believe the typical problems faced when placing a WebView within a View is that View expects children to force the View to expand (that is, a Text component would take up some amount of width and height which the View then accommodates). WebView, on the other hand, expands to the size of the parent component unless a style is passed specifying the width. Therefore, a simple <View><WebView /></View> results in a 0 width and nothing shown on the screen. The earlier solutions of setting the WebView width work well but require either the device dimensions to be fetched (which might not be the desired width) or for the View to have an onLayout function AND have some way to expand the View to the desired space. I found it easiest to just apply the flex: 1 and alignSelf: 'stretch' for the View to fill the space as desired and then WebView to automatically follow suit.

Hope this helps someone before it becomes obsolete!

Answer 9

I ran into the same issue recently. And I found that

alignment: 'center'

was causing the issue for me. I commented it and the webView got loaded immediately. I found the solution here : https://github.com/facebook/react-native/issues/5974 'brunocvcunha's' response worked for me.

Answer 10

Let me give the simplest example which will work seamlessly:

import React from 'react';
import { WebView  } from 'react-native';

export default class App extends React.Component {
  render() {
    return (
      <WebView
      source={{uri: 'https://github.com/facebook/react-native'}} 
    />

    );
  }
}

Do not add your WebView component within a view that created problem and webview url is not rendered rather styles of view will be shown.

Answer 11

I had the same issue and spent a day attempting to fix it. I copied in the UIExplorer webview example, and that didn't work.

I ultimately ended up upgrading react and creating a new react-native project and copying the files in there, and that fixed it.

I wish I had a better answer as to why that fixed it, but hopefully that helps

Answer 12

Below is piece of the code which worked for me.

render: function(){
   return(
     <View style={styles.container}>
      <WebView url={'https://m.facebook.com'} style= {styles.webView}/>
     </View>
   );
 }

            </Modal>
        );
    }
}

Answer 14

import { WebView } from 'react-native'; is deprecated

use below line instead

npm install [email protected] --save

then

import HTML from 'react-native-render-html';

react-native-render-html starting with version 4.2.0, react-native-webview is now a peer dependency. As a result, you need to install it yourself.

Answer 15

Try

<WebView
  source={{ uri: "https://inhall.in/" }}
  style={Styles.webView}
  javaScriptEnabled={true}
  scalesPageToFit />

javaScriptEnabled={true} might help
