Angular 16 Firebase Login with Twitter Example

Last Updated on by in Angular

I am going to show you how you can build login with Twitter using Firebase database with Angular feature with Real-time database.

Firebase offers various auth provider Apis for the user authentication system. In order to create Firebase Twitter login service, you must set up a basic Angular project and create Firebase account set up a project in Firebase account.

Once you are done with the above process then you must enter in your project directory and setup AngularFire2 real-time database library from the node package manager community.

After that you can easily build Angular Firebase Twitter login service It will let your users authenticate with Twitter auth provider with Angular.

Step: 1 – Set up Angular App

ng new angularfirebaseproject

Your basic project is set to be used the second step is to enter into the project folder by using the following command.

cd angularfirebaseproject

Next, to remove strict type warnings or error make sure to set “strict”: false under compilerOptions property in tsconfig.json file.

Step: 2 – Setup AngularFire2 Library

Now setup Firebase (AngularFire2 library) in your Angular project.

npm install @angular/fire firebase@9.16.0 --legacy-peer-deps

You’ve successfully installed AngularFire2 library from NPM community, let’s make the communication between your Firebase account and your Angular app.

First, create src/environments/ folder and environment.ts file, then add firebase configurations in environments/environment.ts file.

export const environment = {
  production: false,
  firebase: {
    apiKey: "xxxxxxxx-xxxxxxxx",
    authDomain: "xxxxxxxxxxxxxxxxxxxxxxxx",
    databaseURL: "xxxxxxxxxxxxxxxxxxxxxxxx",
    projectId: "xxxxxxxx",
    storageBucket: "xxxxxxxx",
    messagingSenderId: "xxxxxx",
    appId: "xxxxx",
    measurementId: "xxxxxxxxxxxxxxxx"

Step: 3 – Enable Twitter Auth Provider Service in Firebase Account

Go to your Firebase account and click on Authenticate button on the sidebar navigation menu then click in front of the Twitter link.

Firebase Twitter Credentials Setting

Enter your Twitter API key and API secret token then click on the save button. This method will activate your Twitter auth provider service from Firebase backend.

Step: 4 – Create Auth Service and Sign in component

Create auth.service.ts core file which will hold our main logic.

ng generate service auth

Step: 5 – Generate Main Auth Service

Go to your auth.service.ts template.

import { Injectable } from '@angular/core';
import { TwitterAuthProvider } from 'firebase/auth';
import { AngularFireAuth } from '@angular/fire/compat/auth';
  providedIn: 'root',
export class AuthService {
    public afAuth: AngularFireAuth // Inject Firebase auth service
  ) {}
  // Sign in with Twitter
  TwitterAuth() {
    return this.AuthLogin(new TwitterAuthProvider());
  // Auth logic to run auth providers
  AuthLogin(provider) {
    return this.afAuth
      .then((result) => {
        console.log('You have been successfully logged in!');
      .catch((error) => {

Go to your app.component.ts template.

import { Component } from '@angular/core';
import { AuthService } from './auth.service';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
export class AppComponent {
  constructor(public authService: AuthService) {}

Step: 6 – Implement Twitter Login Auth Provider Service

Integrate Twitter login service in app.component.html template.

<div class="formGroup">
  <button type="button" (click)="authService.TwitterAuth()">
    Log in with Twitter

Here is the final reference of app module class, you may add the given code in the the app.module.ts file.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { AuthService } from './auth.service';
import { AngularFireModule } from '@angular/fire/compat';
import { AngularFireAuthModule } from '@angular/fire/compat/auth';
import { AngularFireStorageModule } from '@angular/fire/compat/storage';
import { AngularFirestoreModule } from '@angular/fire/compat/firestore';
import { AngularFireDatabaseModule } from '@angular/fire/compat/database';
import { environment } from '../environments/environment';
  declarations: [AppComponent],
  imports: [
  providers: [AuthService],
  bootstrap: [AppComponent],
export class AppModule {}

We are ready to view the application on the browser.

ng serve --open
