Step 1: Set up your Firebase project

  1. Create a new Firebase project or use an existing one at the Firebase console (https://console.firebase.google.com/).
  2. Enable the authentication provider you want to use for SSO (e.g., Google, Facebook, etc.) in the Firebase console.

Step 2: Install Firebase SDK and AngularFire

  1. Install Firebase and AngularFire packages using npm code
npm install firebase @angular/fire

Step 3: Configure AngularFire in your Angular app

  1. Import the necessary modules in your app.module.ts file:typescriptCopy codeimport { AngularFireModule } from '@angular/fire'; import { AngularFireAuthModule } from '@angular/fire/auth';
  2. Add the Firebase configuration to the imports section of app.module.ts:typescriptCopy codeconst firebaseConfig = { // Your Firebase project configuration }; @NgModule({ imports: [ AngularFireModule.initializeApp(firebaseConfig), AngularFireAuthModule ], // ... }) export class AppModule { }

Step 4: Create a login component

  1. Create a new Angular component for the login page, for example login.component.ts and login.component.html.
  2. In the login.component.ts, import the necessary modules and services:typescriptCopy codeimport { Component } from '@angular/core'; import { AngularFireAuth } from '@angular/fire/auth'; @Component({ selector: 'app-login', templateUrl: './login.component.html', styleUrls: ['./login.component.css'] }) export class LoginComponent { constructor(private afAuth: AngularFireAuth) { } // Implement your login logic here }
  3. In the login.component.html, add the login button or form according to your SSO provider:htmlCopy code<button (click)="loginWithGoogle()">Login with Google</button>
  4. Implement the login method in login.component.ts to authenticate with the chosen SSO provider:typescriptCopy codeasync loginWithGoogle() { try { await this.afAuth.signInWithPopup(new firebase.auth.GoogleAuthProvider()); // Handle successful login } catch (error) { // Handle login error } }

You can customize the login component and implement additional features like error handling, redirects, etc., as per your requirements. Remember to import necessary modules and services and configure the Firebase project with the appropriate SSO provider in the Firebase console.
