## Maintainers | Maintainer | GitHub | Social | | ---------- | ----------------------------------------- | --------------------------------------------- | | Robin Genz | [robingenz](https://github.com/robingenz) | [@robin_genz](https://twitter.com/robin_genz) | ## Installation ``` npm install @robingenz/capacitor-firebase-authentication firebase npx cap sync ``` Add Firebase to your project if you haven't already ([Android](https://firebase.google.com/docs/android/setup) / [iOS](https://firebase.google.com/docs/ios/setup) / [Web](https://firebase.google.com/docs/web/setup)). On **iOS**, verify that this function is included in your app's `AppDelegate.swift`: ```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](docs/setup-apple.md) - [Facebook Sign-In](docs/setup-facebook.md) - [GitHub Sign-In](docs/setup-github.md) - [Google Sign-In](docs/setup-google.md) - [Microsoft Sign-In](docs/setup-microsoft.md) - [Play Games Sign-In](docs/setup-play-games.md) - [Twitter Sign-In](docs/setup-twitter.md) - [Yahoo Sign-In](docs/setup-yahoo.md) - [Phone Number Sign-In](docs/setup-phone.md) - [Custom Token Sign-In](docs/custom-token.md) **Attention**: Please note that this plugin uses third-party SDKs to offer native sign-in. These SDKs can initialize on their own and collect various data. [Here](docs/third-party-sdks.md) you can find more information. ## Configuration These configuration values are available: | Prop | Type | Description | Default | | -------------------- | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | **`skipNativeAuth`** | boolean | Configure whether the plugin should skip the native authentication. Only needed if you want to use the Firebase JavaScript SDK. Only available for Android and iOS. | false | | **`providers`** | string[] | Configure which providers you want to use so that only the providers you need are fully initialized. If you do not configure any providers, they will be all initialized. Please note that this does not prevent the automatic initialization of third-party SDKs. Only available for Android and iOS. | ["apple.com", "facebook.com", "github.com", "google.com", "microsoft.com", "playgames.google.com", "twitter.com", "yahoo.com", "phone"] | ### Examples In `capacitor.config.json`: ```json { "plugins": { "FirebaseAuthentication": { "skipNativeAuth": false, "providers": ["apple.com", "google.com"] } } } ``` In `capacitor.config.ts`: ```ts /// import { CapacitorConfig } from '@capacitor/cli'; const config: CapacitorConfig = { plugins: { FirebaseAuthentication: { skipNativeAuth: false, providers: ["apple.com", "google.com"], }, }, }; export default config; ``` ## Demo A working example can be found here: [robingenz/capacitor-firebase-authentication-demo](https://github.com/robingenz/capacitor-firebase-authentication-demo) ## Usage ```typescript import { FirebaseAuthentication } from '@robingenz/capacitor-firebase-authentication';

(change: AuthStateChange): void ## FAQ 1. **What does this plugin do?** This plugin enables the use of [Firebase Authentication](https://firebase.google.com/docs/auth) in a Capacitor app. It uses the Firebase SDK for [Java](https://firebase.google.com/docs/reference/android) (Android), [Swift](https://firebase.google.com/docs/reference/swift) (iOS) and [JavaScript](https://firebase.google.com/docs/reference/js). 1. **What is the difference between the web implementation of this plugin and the Firebase JS SDK?** The web implementation of this plugin encapsulates the Firebase JS SDK and enables a consistent interface across all platforms. You can decide if you prefer to use the web implementation or the Firebase JS SDK. 1. **What is the difference between the native and web authentication?** For web authentication, the Firebase JS SDK is used. This only works to a limited extent on Android and iOS in the WebViews (see [here](https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html)). For native authentication, the native SDKs from Firebase, Google, etc. are used. These offer all the functionalities that the Firebase JS SDK also offers on the web. However, after a login with the native SDK, the user is only logged in on the native layer of the app. If the user should also be logged in on the web layer, additional steps are required (see [here](https://github.com/robingenz/capacitor-firebase-authentication/blob/main/docs/firebase-js-sdk.md)). 1. **How can I use this plugin with the Firebase JavaScript SDK?** See [here](https://github.com/robingenz/capacitor-firebase-authentication/blob/main/docs/firebase-js-sdk.md). ## Changelog See [CHANGELOG.md](CHANGELOG.md). ## License See [LICENSE](LICENSE).
