php artisan jetstream:install livewire

Now, let's node js package:

npm install

let's run package:

npm run dev

Now, we need to run migration command to create database table:

php artisan migrate

Step 3: Install Socialite

In first step we will install Socialite Package that provide api to connect with google account. So, first open your terminal and run bellow command:

composer require laravel/socialite

after creating an account you can copy the client id and secret.

config/services.php

return [
    ....
    'google' => [
        'client_id' => 'app id',
        'client_secret' => 'add secret',
        'redirect' => 'http://localhost:8000/auth/google/callback',
    ],
]

Step 4: Add Database Column

In this step first we have to create migration for add google_id in your user table. So, let's run bellow command:

php artisan make:migration add_google_id_column

**Migration

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

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

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        //
    }
}

Update mode like this way:

app/Models/User.php

<?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',
    ];
}

Step 5: Create Routes

After adding google_id column first we have to add new route for google login. so let's add bellow route in routes.php file.

app/Http/routes.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\GoogleController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

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

Step 6: Create Controller

After add route, we need to add method of google auth that method will handle google callback url and etc, first put bellow code on your GoogleController.php file.

app/Http/Controllers/GoogleController.php

<?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());
        }
    }
}

Step 7: Update Blade File

Ok, now at last we need to add blade view so first create new file login.blade.php file and put bellow code:

resources/views/auth/login.blade.php

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

        <x-jet-validation-errors class="mb-4" />

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

        <form method="POST" action="{{ route('login') }}">
            @csrf

            <div>
                <x-jet-label value="Email" />
                <x-jet-input class="block mt-1 w-full" type="email" name="email" :value="old('email')" required autofocus />
            </div>

            <div class="mt-4">
                <x-jet-label value="Password" />
                <x-jet-input class="block mt-1 w-full" type="password" name="password" required autocomplete="current-password" />
            </div>

            <div class="block mt-4">
                <label class="flex items-center">
                    <input type="checkbox" class="form-checkbox" name="remember">
                    <span class="ml-2 text-sm text-gray-600">{{ __('Remember me') }}</span>
                </label>
            </div>

            <div class="flex items-center justify-end mt-4">
                @if (Route::has('password.request'))
                    <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">
                <a href="{{ url('auth/google') }}">
                    <img src="https://developers.google.com/identity/images/btn_google_signin_dark_normal_web.png" style="margin-left: 3em;">
                </a>
            </div>
        </form>
    </x-jet-authentication-card>
</x-guest-layout>
