In React Native, WebViews enable access to any web portal in the mobile app itself. In other words, a web view allows us to open the web URLs inside the app interface. While React Native provides us with a built-it web view component, but we are going to use react-native-webview plugin in this tutorial, since it is more powerful. React Native WebView is a modern, well-supported, and cross-platform WebView for React Native.
The built-in Webview from React Native is to be deprecated pretty soon based on this document. Hence, this plugin serves as the replacement for the built-in web view. This plugin is a third-party plugin supported by the react-native community.
The requirements to follow this tutorial are:
Getting Started with React Native WebView
In order to get started with web view configuration, we need to install the actual plugin first. Here, we are using yarn to install the plugin but we can use NPM (Node Package Manager) as well. Hence, in order to install the plugin, we need to run the following command in the command prompt of our project folder:
yarn add react-native-webview
If the react-native version is equal or greater than 0.60 then, the installation also takes care of auto-linking the plugin to native configurations. But, in the case of earlier versions, we may need to run:
react-native link react-native-webview
In the case of iOS, we also need to run the following command:
pod install
In the case of Android, this module does not require any extra step after running the link command. But for the react-native-webview version >=6.X.X, we need to make sure AndroidX is enabled in our project. This can be done by editing
and adding the following lines:
This completes our installation steps. We can now use the plugin in our react native project.
Loading Inline HTML using React Native WebView
First, we are going to load a simple HTML content into our app interface. For that, we need to add the following imports in our _App.js_ file:
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
Here, we have imported the
component from the _react-native-webview_ plugin. Now, we can make use of this component in order to load the HTML content as shown in the code snippet below:
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
class MyInlineWeb extends Component {
  render() {
    return (
        source={{ html: '<h1>This is a static HTML source!</h1>' }}
Here, we have defined the
class component. This class component has a
function that renders the
component. The
component has the HTML content configured to its
prop. As a result, we can see the HTML content is rendered in the app interface as shown in the emulator screenshot below:
Loading Remote URL
Now, instead of simple HTML content, we are going to load the entire website content from the remote URL. For that, we need to provide the
option to the
prop of
component as shown in the code snippet below:
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
class MyWeb extends Component {
  render() {
    return <WebView source={{ uri: 'https://instamobile.io/blog' }} />;
Hence, we will get the entire webpage of the website opened in the app’s web view itself as shown in the screenshot below:
Adding a loading spinner to React Native Webview
While accessing the URL from the
component, it may take some time for entire HTML content on the website to load. So, in order to represent the delay, we are going to display a loading indicator until the website loads. For this, we need to import the
component from the react-native package as shown in the code snippet below:
import { Text, View, StyleSheet, ActivityIndicator } from 'react-native';
Now, we need to make use of the
component in our project. For that, we are going to create a function called
which will return the
as shown in the code snippet below:
import * as React from 'react';
import { Text, View, StyleSheet,ActivityIndicator } from 'react-native';
import { WebView } from 'react-native-webview';
import { Card } from 'react-native-paper';
 function LoadingIndicatorView() {
    return <ActivityIndicator color='#009b88' size='large' />
export default function App() {
  return (
        source={{ uri: 'https://instamobile.io/blog' }}  
Here, we have used the
props. Then, we have invoked the
function onto the
prop of the
component. This allows us to display the loading indicator until the website fully loads.
We can see that
prop is also used here. This boolean value forces the
to show the loading view on the first load. This prop must be set to
in order for the
prop to work.
As a result, we get the following result in our emulator simulation:
In this tutorial, we learned about the web view property of React Native. Since the in-built web-view feature of React Native is to be deprecated, we learned how to make use of the third party web view plugin named _ react-native-webview. First, we learned how to render the simple HTML content using the WebView component. Then, we got a detailed explanation of how to use the WebView component and its props to render the entire HTML content from the URL along with the loading indicator. In case you want to learn more, you can go-ahead to the main repository for discussion regarding this web view plugin.
At Instamobile, we used a webview to automatically display all the web pages of a WordPress site, as part of our React Native WordPress app.
