InAppBrowser for NativeScript

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

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

Getting started

tns plugin add nativescript-inappbrowser

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.ts

import { android } from "tns-core-modules/application";
export const getDeepLink = (path = "") => {
  const scheme = 'my-scheme';
  const prefix = android ? `${scheme}://my-host/` : `${scheme}://`;
  return prefix + path;
}

• home-page.ts

import { openUrl } from 'tns-core-modules/utils/utils';
import InAppBrowser from 'nativescript-inappbrowser';
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
          ) {
            openUrl(response.url)
          }
        })
      } else openUrl(url)
    } catch (error) {
      openUrl(url)
    }
  }
...

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.
