Laravel Socialite Facebook Login

In this post i am going to explain about Laravel Socialite Authentication using Facebook.

To Start with follow the below steps.

STEP 1

Install Laravel Socialite Package using composer.

composer require laravel/socialite

NOTE: If Using Laravel lower than version 8 Include Package in Providers.
In config/app.php file add the below provider

Laravel\Socialite\SocialiteServiceProvider::class,

Scroll Down to aliases section and add below code

'Socialite' => Laravel\Socialite\Facades\Socialite::class,

Step 2

Include Facebook Service in config/services.php file.

'facebook' => [
        'client_id' => '', //USE FROM FACEBOOK DEVELOPER ACCOUNT
        'client_secret' => '', //USE FROM FACEBOOK DEVELOPER ACCOUNT
        'redirect' => 'https://examplelaravel8.test/facebook/callback/'
    ],

STEP 3

Here, you have to create Facebook app so that you can get a client_id and client_secret from Facebook.

You can do this by going to Facebook’s developers URL

and log in with your Facebook account.

Go to My Apps, proceed to Add New App

STEP 4

Create a new controller to handle socialite action. Run below command to generate a new controller

php artisan make:controller FaceBookController

Update FacebookController With Code Below Which have 2 Function To Redirect and To handle Callback.

<?php

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Laravel\Socialite\Facades\Socialite;

class FaceBookController extends Controller
{
/**
 * Login Using Facebook
 */
 public function loginUsingFacebook()
 {
    return Socialite::driver('facebook')->redirect();
 }

 public function callbackFromFacebook()
 {
  try {
       $user = Socialite::driver('facebook')->user();

       $saveUser = User::updateOrCreate([
           'facebook_id' => $user->getId(),
       ],[
           'name' => $user->getName(),
           'email' => $user->getEmail(),
           'password' => Hash::make($user->getName().'@'.$user->getId())
            ]);

       Auth::loginUsingId($saveUser->id);

       return redirect()->route('home');
       } catch (\Throwable $th) {
          throw $th;
       }
   }
}

STEP 5

Add Facebook authentication routes

// Facebook Login URL
Route::prefix('facebook')->name('facebook.')->group( function(){
    Route::get('auth', [FaceBookController::class, 'loginUsingFacebook'])->name('login');
    Route::get('callback', [FaceBookController::class, 'callbackFromFacebook'])->name('callback');
});

STEP 6

ADD Facebook Button on Login Page resources/views/auth/login.blade.php

 <a href="{{ route('facebook.login') }}" class="btn btn-facebook btn-user btn-block">
   <i class="fab fa-facebook-f fa-fw"></i>
   Login with Facebook
</a>

STEP 7

Add facebook_id Column in Users table, create a migration be command below

php artisan make:migration add_facebook_id_in_users_table

Add Below Code in Migration file

 /**
 * Run the migrations.
 *
 * @return void
 */
 public function up()
 {
    Schema::table('users', function (Blueprint $table) {
        $table->string('facebook_id')->nullable();
    });
 }

 /**
 * Reverse the migrations.
 *
 * @return void
 */
 public function down()
 {
   Schema::table('users', function (Blueprint $table) {
       $table->dropColumn('facebook_id');
   });
 }

and run migration

php artisan migrate

STEP 8

Update The User Model Fillable Property in Models/User.php

protected $fillable = [
        'name',
        'email',
        'password',
        'status',
        'facebook_id'
];

Finally Go To Login Page And Try Accessing Login With Facebook Button.
