Google authentication with Laravel

Google authentication with Laravel


  • First create a Laravel project
        composer create-project --prefer-dist laravel/laravel googleLogin

  • Now we have to install Jetstream
        composer require laravel/jetstream

  • Now we have to create the authentication. For this you can create basic login, registration and email verification
        php artisan jetstream:install livewire

  • Now install the node.js package
        npm install

  • Then run
        npm run dev

  • Create a database and migrate the tables
        php artisan migrate

  • Now, we will install Socialite Package that provide api to connect with google account
        composer require laravel/socialite

  • Now you have to create Google App in Google Developer Console
  • First create an app in OAuth Consent Screen
  • Then go to Credentials and click create credentials and select OAuth client ID

  • Choose web application and set the URI as http://localhost:8000. And set the redirecting URI also. This should be same as the redirect value in services.php file. If your site is hosted set the hosted URI
  • Save and it will generate the client id and client secret. Set those in the config/services.php
        'google' => [
        'client_id' => 'app id',
        'client_secret' => 'add secret',
        'redirect' => 'http://localhost:8000/auth/google/callback',
        ],

  • Add google_id for the user table
        php artisan make:migration add_google_id_column

  • Update the newly created migration file
        


  • Change the User.php model
<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Fortify\TwoFactorAuthenticatable;
use Laravel\Jetstream\HasProfilePhoto;
use Laravel\Sanctum\HasApiTokens;
  
class User extends Authenticatable
{
    use HasApiTokens;
    use HasFactory;
    use HasProfilePhoto;
    use Notifiable;
    use TwoFactorAuthenticatable;
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
        'google_id'
    ];
  
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
        'two_factor_recovery_codes',
        'two_factor_secret',
    ];
  
    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
  
    /** 
     * The accessors to append to the model's array form.
     *
     * @var array
     */
    protected $appends = [
        'profile_photo_url',
    ];
}

  • Create the routes
Route::get('auth/google', [GoogleController::class, 'redirectToGoogle']);
Route::get('auth/google/callback', [GoogleController::class, 'handleGoogleCallback']);

  • Create the controller
        php artisan make:controller GoogleController

  • Update the controller
<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use Laravel\Socialite\Facades\Socialite;
use Exception;
use App\Models\User;
use Illuminate\Support\Facades\Auth;
  
class GoogleController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function redirectToGoogle()
    {
        return Socialite::driver('google')->redirect();
    }
        
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function handleGoogleCallback()
    {
        try {
      
            $user = Socialite::driver('google')->user();
       
            $finduser = User::where('google_id', $user->id)->first();
       
            if($finduser){
       
                Auth::login($finduser);
      
                return redirect()->intended('dashboard');
       
            }else{
                $newUser = User::create([
                    'name' => $user->name,
                    'email' => $user->email,
                    'google_id'=> $user->id,
                    'password' => encrypt('123456dummy')
                ]);
      
                Auth::login($newUser);
      
                return redirect()->intended('dashboard');
            }
      
        } catch (Exception $e) {
            dd($e->getMessage());
        }
    }
}

  • Update the welcome.blade file

<x-guest-layout>
    <x-jet-authentication-card>
        <x-slot name="logo">
            <x-jet-authentication-card-logo />
        </x-slot>

        @if (session('status'))
            <div class="mb-4 font-medium text-sm text-green-600">
                {{ session('status') }}
            </div>
        @endif
  
        <form method="POST" action="{{ route('login') }}">

                    <a class="underline text-sm text-gray-600 hover:text-gray-900" href="{{ route('password.request') }}">
                        {{ __('Forgot your password?') }}
                    </a>
                @endif
  
                <x-jet-button class="ml-4">
                    {{ __('Login') }}
                </x-jet-button>
            </div>
            <div class="flex items-center justify-end mt-4">
