react-native-webview

What is react-native-webview?

The react-native-webview package is a powerful tool for embedding web content into a React Native application. It allows developers to render web pages, handle navigation, and interact with web content using JavaScript. This package is highly customizable and supports various features such as injecting JavaScript, handling navigation events, and more.

What are react-native-webview's main functionalities?

Basic WebView

This feature allows you to embed a basic web page within your React Native application. The WebView component takes a source prop that specifies the URL of the web page to be loaded.

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

const MyWebView = () => (
  <WebView
    source={{ uri: 'https://www.example.com' }}
    style={{ marginTop: 20 }}
  />
);

export default MyWebView;

Injecting JavaScript

This feature allows you to inject JavaScript into the web page being loaded. The injectedJavaScript prop takes a string of JavaScript code that will be executed once the page has loaded.

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

const MyWebView = () => (
  <WebView
    source={{ uri: 'https://www.example.com' }}
    injectedJavaScript={"document.body.style.backgroundColor = 'red';"}
    style={{ marginTop: 20 }}
  />
);

export default MyWebView;

Handling Navigation Events

This feature allows you to handle navigation events within the WebView. The onNavigationStateChange prop takes a function that will be called whenever the navigation state changes, providing details about the navigation event.

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

const MyWebView = () => (
  <WebView
    source={{ uri: 'https://www.example.com' }}
    onNavigationStateChange={(navState) => {
      console.log('Navigation state changed:', navState);
    }}
    style={{ marginTop: 20 }}
  />
);

export default MyWebView;

Other packages similar to react-native-webview

react-native-inappbrowser-reborn

The react-native-inappbrowser-reborn package allows you to open web content in an in-app browser. It provides a more native feel compared to a WebView and supports features like custom animations and toolbar customization. However, it is not as flexible as react-native-webview for embedding web content directly within your application.

README

React Native WebView

React Native WebView is a community-maintained WebView component for React Native. It is intended to be a replacement for the built-in WebView (which was removed from core).

Maintainers

Many thanks to these companies for providing us with time to work on open source.
Please note that maintainers spend a lot of free time working on this too so feel free to sponsor them, it really makes a difference.

• Thibault Malbranche (Twitter @titozzz) from Brigad
  Sponsor me ❤️ !

Windows and macOS are managed by Microsoft, notably:

• Alexander Sklar (Twitter @alexsklar) from React Native for Windows
• Chiara Mooney from React Native for Windows @ Microsoft

Shout-out to Jamon Holmgren from Infinite Red for helping a lot with the repo when he had more available time.

Disclaimer

Maintaining WebView is very complex because it is often used for many different use cases (rendering SVGs, PDFs, login flows, and much more). We also support many platforms and both architectures of react-native.

Since WebView was extracted from the React Native core, nearly 500 pull requests have been merged.
Considering that we have limited time, issues will mostly serve as a discussion place for the community, while we will prioritize reviewing and merging pull requests.

Platform compatibility

This project is compatible with iOS, Android, Windows and macOS.
This project supports both the old (paper) and the new architecture (fabric).
This project is compatible with expo.

Getting Started

Read our Getting Started Guide. If any step seems unclear, please create a pull request.

Versioning

This project follows semantic versioning. We do not hesitate to release breaking changes but they will be in a major version.

Usage

Import the WebView component from react-native-webview and use it like so:

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

// ...
const MyWebComponent = () => {
  return <WebView source={{ uri: 'https://reactnative.dev/' }} style={{ flex: 1 }} />;
}

Common issues

• If you're getting Invariant Violation: Native component for "RNCWebView does not exist" it likely means you forgot to run react-native link or there was some error with the linking process
• If you encounter a build error during the task :app:mergeDexRelease, you need to enable multidex support in android/app/build.gradle as discussed in this issue
