Authentication Flow using Deep Linking

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

const Main = createStackNavigator(
  {
    LoginComponent: { screen: LoginComponent },
    HomeComponent: { screen: HomeComponent },
    SplashComponent: { //Redirect users to the Home page if they are authenticated, otherwise to Login page...
      screen: SplashComponent,
      path: 'callback/' //Deep linking 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 {
      await InAppBrowser.isAvailable()
      InAppBrowser.openAuth(url, deepLink, {
        // iOS Properties
        dismissButtonStyle: 'cancel',
        // Android Properties
        showTitle: false,
        enableUrlBarHiding: true,
        enableDefaultShare: true,
      }).then((response) => {
        if (response.type === 'success' && 
          response.url) {
          Linking.openURL(response.url)
        }
      })
    } catch (error) {
      Linking.openURL(url)
    }
  }
...
  • SplashComponent
...
  componentWillMount() {
    const { navigation } = this.props
    const { state: { params } } = navigation
    const { access_token } = params || {}

    if (access_token) {
      // Opened by deep linking, the user is authenticated
      // Redirect to the Home page
    }
    else {
      // Detect if the stored token is still valid
      // And redirect the user to Home or Login page
    }
  }
