About

This plugin is an implementation of Firebase Auth using the native Firebase SDK for Java (Android) and Swift (iOS). When using this plugin the user will be authenticated into the native layer. This means that you can use other native plugins that require authenticated firebase users.

If you also want to use the Firebase JS SDK in your app, you will need to make sure that the web layer also gets authenticated. This is not yet built into this plugin by default. See #41 for more information on this.

Installation

npm install @robingenz/capacitor-firebase-authentication
npx cap sync

Add Firebase to your project if you haven't already (Android / iOS).

On iOS, verify that this function is included in your app's AppDelegate.swift:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
  return ApplicationDelegateProxy.shared.application(app, open: url, options: options)
}

The further installation steps depend on the selected authentication method:

• Apple Sign-In
• GitHub Sign-In
• Google Sign-In
• Microsoft Sign-In
• Twitter Sign-In
• Yahoo Sign-In

Configuration

No configuration required for this plugin.

Usage

  const result = await FirebaseAuthentication.getCurrentUser();
  return result.user;
};

const getIdToken = async () => {
  const result = await FirebaseAuthentication.getIdToken();
  return result.token;
};

const setLanguageCode = async () => {
  await FirebaseAuthentication.setLanguageCode({ languageCode: 'en-US' });
};

const signInWithApple = async () => {
  await FirebaseAuthentication.signInWithApple();
};

const signInWithGithub = async () => {
