    To install this library, run:

    $ npm install firebaseui-angular --save

    To run this library you need to have AngularFire2, Firebase, FirebaseUI-Web installed. Fast install:

    $ npm install firebase firebaseui @angular/fire firebaseui-angular --save

    How to use

    Add the FirebaseUIModule with the config to your imports. Make sure you have initialized AngularFire correctly.

    import {BrowserModule} from '@angular/platform-browser';
    import {NgModule} from '@angular/core';
    import {FormsModule} from '@angular/forms';
    import {AppComponent} from './app.component';
    import {firebase, firebaseui, FirebaseUIModule} from 'firebaseui-angular';
    import {environment} from '../environments/environment';
    import {AppRoutingModule} from './app-routing.module';
    import {AngularFireModule} from '@angular/fire';
    import {AngularFireAuthModule, USE_EMULATOR as USE_AUTH_EMULATOR} from '@angular/fire/auth';
    const firebaseUiAuthConfig: firebaseui.auth.Config = {
      signInFlow: 'popup',
      signInOptions: [
          scopes: [
          customParameters: {
            'auth_type': 'reauthenticate'
          provider: firebase.auth.FacebookAuthProvider.PROVIDER_ID
          requireDisplayName: false,
          provider: firebase.auth.EmailAuthProvider.PROVIDER_ID
      tosUrl: '<your-tos-link>',
      privacyPolicyUrl: '<your-privacyPolicyUrl-link>',
      credentialHelper: firebaseui.auth.CredentialHelper.GOOGLE_YOLO
      declarations: [
      imports: [
      providers: [
        { provide: USE_AUTH_EMULATOR, useValue: !environment.production ? ['localhost', 9099] : undefined },
      bootstrap: [AppComponent]
    export class AppModule {

    Add the firebaseui css to your imports:

    Option 1: CSS Import

    May be incompatible with older browsers.

    Import the firebaseui css to your src/styles.css file:

    @import '~firebaseui/dist/firebaseui.css';

    Option 2: Angular-CLI

    File: angular.json

    Path: "node_modules/firebaseui/dist/firebaseui.css"

      "projects": {
        [your-project-name]: {
          "architect": {
            "build": {
              "options": {
                "styles": [
            "test": {
              "options": {
                "styles": [

    Option 3: HTML Link

    Put this in the <head> tag of your index.html file:

    <link type="text/css" rel="stylesheet" href="https://cdn.firebase.com/libs/firebaseui/3.0.0/firebaseui.css" />

    Make sure the version number matches the version of firebaseui you have installed with npm.

    Once everything is set up, you can use the component in your Angular application:



    For the configuration of the module see the official firebaseui documentation: Config

    If you use a version prior to 3.3.0 check the old README


    To configure the plugin the first time (main.module.ts) the forRoot() method is used. It builds the basis for all further uses of the plugin. But you have the possibility to overwrite the entire or just parts of the configuration in any (sub-)module.


    To overwrite the entire configuration use:

    FirebaseUIModule.forRoot(firebaseUiAuthConfig: NativeFirebaseUIAuthConfig)

    To overwrite just parts of the configuration use:

    FirebaseUIModule.forFeature(firebaseUiAuthConfig: NativeFirebaseUIAuthConfig)

    This will use the in forRoot provided configuration and overwrite just the newly provided values.

    Listen to auth state changes

    private firebaseAuthChangeListener(response) {
        // if needed, do a redirect in here
        if (response) {
          console.log('Logged in :)');
        } else {
          console.log('Logged out :(');

    Don't forget to unsubscribe at the end.

    Sign-in success / failure callbacks

    successCallback(signInSuccessData: FirebaseUISignInSuccessWithAuthResult) {
    errorCallback(errorData: FirebaseUISignInFailure) {
    uiShownCallback() {

    Disable auto sign-in

    constructor(private firebaseuiAngularLibraryService: FirebaseuiAngularLibraryService) {

    Contributing / Sample Application

    Step 1: Fork and clone the repo from Github.

    Step 2: There is a sample project in the root folder. Execute the following command in the root folder i.e. .../FirebaseUI-Angular > npm install

    Step 3: Ensure that you are using Angular CLI version >10. You can check your version with ng --version in the terminal.

    Step 4: Replace with your firebase config in src\environments\environment.ts.

    Step 5: .../FirebaseUI-Angular > npm run build-lib

    Step 6: .../FirebaseUI-Angular > ng serve

    You're welcome to fork the repo and contribute to library sources in projects > firebaseui-angular-library > src > lib.

    There are test files, but they are empty at the moment. Writing unit test is a good start.


    UI not rendered

    The UI only gets rendered if the user isn't signed in. So if the UI isn't shown, sign out the user via angular-fire.

    Prod build error

    ERROR in ./src/app/app.module.ngfactory.js
    Module not found: Error: Can't resolve 'firebase/index' in '...'
    ERROR in ./src/app/app.module.ngfactory.js
    Module not found: Error: Can't resolve 'firebaseui/dist/index' in '...'

    Use the firebase and firebaseui instances exposed by the plugin:

    import {..., firebase, firebaseui} from 'firebaseui-angular';

    CSS not loaded

    If you have added the css to the angular.json but nothing happened. Try to restart the server (Ctrl-C and ng serve)

    ERROR in ./~/firebase/app/shared_promise.js

    This is a know issue in the firebase project. To fix that (for now), do that:

    npm install promise-polyfill --save-exact

    http://localhost:4200/images/buffer.svg?embed 404 (Not Found)

    Put this into your styles.scss file:

    @supports (-webkit-appearance:none) {
      .mdl-progress:not(.mdl-progress--indeterminate):not(.mdl-progress--indeterminate) > .auxbar,
      .mdl-progress:not(.mdl-progress__indeterminate):not(.mdl-progress__indeterminate) > .auxbar {
        mask: url(/assets/images/buffer.svg?embed) !important;

    and put a buffer.svg file into assets/images. This will stop this error message.
