React Native In-App Browser

In-App browser support for React Native, using Chrome Custom Tabs on Android and Safari View Controller on iOS.

Compatibility

⚠️Support has ended on October 1st 2020.

It is recommended migrating to react-native-inappbrowser-reborn for continued support and more features.

React Native	Library	Status	End-of-Life
0.60.0 - 0.62.x		EOL	2020-10-01
0.57.x - 0.59.x		EOL	2020-01-03
0.57.x - 0.59.5		EOL	2019-06-09

Using Expo? Check out WebBrowser.

Installation

Install the package via Yarn or npm:

yarn add @matt-block/react-native-in-app-browser

# or
npm install --save @matt-block/react-native-in-app-browser

Linking

React Native 0.60.0 and later

Packages are autolinked, however an extra step for iOS projects is needed:

cd ios && pod install && cd ..

React Native 0.59.x and below

Manually link the native module to your project:

react-native link @matt-block/react-native-in-app-browser

Note for iOS projects

In order for Xcode projects to build when using Swift-based libraries, your main app project must contain Swift code and a bridging header. If your app project does not contain any Swift code, add a single empty .swift file and an empty bridging header to your app.

If your Xcode project already makes use of Swift code you can safely ignore this note.

Usage

⚠️ Still using an older version ? Check out the migration guides.

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";


// Minimal setup.
InAppBrowser.open("https://www.wikipedia.org/").catch(error => {
  console.log(error);
});


// With platform-specific optional settings.
InAppBrowser.open("https://www.wikipedia.org/", {
  android: {
    //...,
  },
  ios: {
    //...,
  },
}).catch(error => {
  console.log(error);
});


// Using async/await.
async onClickHandler() {
  try {
    await InAppBrowser.open("https://www.wikipedia.org/");
  } catch (error) {
    console.log(error);
  }
}

Startup optimizations (Android only)

Chrome Custom Tabs exposes methods to reduce the start time of a custom tab activity.

For information on how these work, check Custom Tabs - Example and Usage Optimization

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";

InAppBrowser.warmup();
InAppBrowser.mayLaunchUrl("https://wikipedia.org");

Programmatically close (iOS only)

It is possible to manually dismiss the iOS in-app instance by calling the method close.

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";

InAppBrowser.close();

This is not possible on Android since Chrome Custom Tabs do not expose such functionality and Activity workarounds would bring this package way out of scope.

Settings

The main method open accepts an object with settings objects for each platform:

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";

InAppBrowser.open("https://www.wikipedia.org/", {
  android: {},
  ios: {}
});

Settings can also be initialized separately with configure so that each open call won't need to specify them each time:

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";

// Somewhere in your app initialization logic.
InAppBrowser.configure({
  android: {},
  ios: {}
});

// Other part of your code base.
// Previously initialized settings will apply.
InAppBrowser.open("https://www.wikipedia.org/");

Note that open will still accept settings as always but will effectively perform a merge between the initialized properties and the provided settings object (which will have priority over the initialized properties):

import { InAppBrowser } from "@matt-block/react-native-in-app-browser";

// Somewhere in your app initialization logic.
InAppBrowser.configure({
  android: {
    toolbarColor: "red",
    showTitle: true
  }
});

// Other part of your code base.
// Merged settings for this call will result in:
//
// - toolbarColor: "blue",
// - showTitle: true
InAppBrowser.open("https://www.wikipedia.org/", {
  android: {
    toolbarColor: "blue"
  }
});

The properties for each platform settings are described below.

Each setting is optional. Furthermore, settings with invalid values will be ignored and their default values will be used.
