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.
