InAppBrowser for React Native

Provides access to the system's web browser and supports handling redirects

Chrome Custom Tabs for Android & SafariServices/AuthenticationServices for iOS.

Getting started

$ npm install react-native-inappbrowser-reborn --save

Mostly automatic installation

Using React Native >= 0.60

Linking the package manually is not required anymore with Autolinking.

iOS Platform:

$ cd ios && pod install && cd .. # CocoaPods on iOS needs this extra step

Android Platform with Android Support:

Using Jetifier tool for backward-compatibility.

Modify your android/build.gradle configuration:

buildscript {
  ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 28
    # Only using Android Support libraries
    supportLibVersion = "28.0.0"
  }

Android Platform with AndroidX:

Modify your android/build.gradle configuration:

buildscript {
  ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 28
    # Remove 'supportLibVersion' property and put specific versions for AndroidX libraries
    androidXAnnotation = "1.1.0"
    androidXBrowser = "1.0.0"
    // Put here other AndroidX dependencies
  }

Using React Native < 0.60

$ react-native link react-native-inappbrowser-reborn

Usage

Methods	Action
`open`	Opens the url with Safari in a modal on iOS using SFSafariViewController, and Chrome in a new custom tab on Android. On iOS, the modal Safari will not share cookies with the system Safari.
`close`	Dismisses the system's presented web browser.
`openAuth`	Opens the url with Safari in a modal on iOS using SFAuthenticationSession/ASWebAuthenticationSession, and Chrome in a new custom tab on Android. On iOS, the user will be asked whether to allow the app to authenticate using the given url (OAuth flow with deep linking redirection).
`closeAuth`	Dismisses the current authentication session.
`isAvailable`	Detect if the device supports this plugin.

Authentication Flow using Deep Linking

In order to redirect back to your application from a web browser, you must specify a unique URI to your app. To do this, define your app scheme and replace my-scheme and my-host with your info.

Enable deep linking (Android) - AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="my-scheme" android:host="my-host" android:pathPrefix="" />
</intent-filter>

Enable deep linking (iOS) - Info.plist

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string>my-scheme</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>my-scheme</string>
    </array>
  </dict>
</array>

utilities.js

import { Platform } from 'react-native'
export const getDeepLink = (path = "") => {
  const scheme = 'my-scheme'
  const prefix = Platform.OS == 'android' ? `${scheme}://my-host/` : `${scheme}://`
  return prefix + path
}

App.js (Using react-navigation with Deep Linking)

import { Root } from 'native-base'
import { getDeepLink } from './utilities'
import { createStackNavigator } from 'react-navigation'

const Main = createStackNavigator(
  {
    SplashComponent: { screen: SplashComponent },
    LoginComponent: { screen: LoginComponent },
    HomeComponent: { screen: HomeComponent },
    CallbackComponent: { //Redirect users to the Home page if they are authenticated, otherwise to Login page...
      screen: CallbackComponent,
      path: 'callback/' //Enable Deep linking redirection to get the auth_token
    }
  },
  {
    index: 0,
    initialRouteName: 'SplashComponent',
    headerMode: 'none'
  }
)
...
  render() {
    return (
      <Root>
        <Main uriPrefix={getDeepLink()} />
      </Root>
    )
  }
...

LoginComponent

import { Linking } from 'react-native'
import InAppBrowser from 'react-native-inappbrowser-reborn'
import { getDeepLink } from './utilities'
...
  async onLogin() {
    const deepLink = getDeepLink("callback")
    const url = `https://my-auth-login-page.com?redirect_uri=${deepLink}`
    try {
      if (await InAppBrowser.isAvailable()) {
        InAppBrowser.openAuth(url, deepLink, {
          // iOS Properties
          ephemeralWebSession: false,
          // Android Properties
          showTitle: false,
          enableUrlBarHiding: true,
          enableDefaultShare: false
        }).then((response) => {
          if (
            response.type === 'success' &&
            response.url
          ) {
            Linking.openURL(response.url)
          }
        })
      } else Linking.openURL(url)
    } catch (error) {
      Linking.openURL(url)
    }
  }
...

SplashComponent

...
  async componentDidMount() {
    // Play Lottie Animation :)

    // Validate the stored access token (Maybe with a request)
    // Redirect the user to the Home page if the token is still valid
    // Otherwise redirect to the Login page
  }
...

CallbackComponent

...
  async componentDidMount() {
    // Play Lottie Animation :)
    try {
      await this.loadUserInfo()
      // Redirect to the Home page
    } catch (error) {
      // Show error and redirect the user to the Login page
    }
  }

  async loadUserInfo() {
    const { navigation } = this.props
    const { state: { params } } = navigation
    const { code, error } = params || {}

    if (code) {
      // Get and Save the access token request, user info...
    }
    else {
      return Promise.reject(new Error(error))
    }
  }
...

StatusBar

The StatusBar will keep the last one provided in your app. So if the StatusBar is dark-content before you open the browser this will keep it.

Starting with React Native 0.59 onwards, there is a simpler way of handling this update, without the need of patching StatusBar.

  async openInBrowser(url) {
    try {
      const oldStyle = StatusBar.pushStackEntry({ barStyle: 'dark-content', animate: false });
      await InAppBrowser.open(url)
      StatusBar.popStackEntry(oldStyle);
    } catch (error) {
      Alert.alert(error.message)
    }
  })

For previous versions, you can still apply the method described below.

If you want to change before opening you can do something like

  async openInBrowser(url) {
    try {
      StatusBar.setBarStyle('dark-content')
      await InAppBrowser.open(url)
    } catch (error) {
      Alert.alert(error.message)
    }
  })

If you need to restore the old bar style, after the browser is dismissed, you can try and patch the StatusBar.setBarStyle function to store the old value like so:

// patch StatusBar.setBarStyle to make style accessible
const _setBarStyle = StatusBar.setBarStyle
StatusBar.setBarStyle = (style) => {
  StatusBar.currentStyle = style
  _setBarStyle(style)
}

You can than restore the old bar style after the browser has been dismissed like this:

  async openInBrowser(url) {
    try {
      const oldStyle = StatusBar.currentStyle
      StatusBar.setBarStyle('dark-content')
      await InAppBrowser.open(url)
      if(oldStyle) StatusBar.setBarStyle(oldStyle)
    } catch (error) {
      Alert.alert(error.message)
    }
  })

Authentication

Using in-app browser tabs (like SFAuthenticationSession/ASWebAuthenticationSession and Android Custom Tabs) where available. Embedded user-agents, known as web-views (like UIWebView and WKWebView), are explicitly not supported due to the usability and security reasons documented in Section 8.12 of RFC 8252.
