In this blog I will be explaining how to integrate gmail sign-in in laravel which is completely free including the google api's. So let's get started.

1. Install the laravel project. (refer my previous blogs or visit the website mrunali.in)

2. Install Auth

3. Now we will see how to add credentials

Run the following command in your terminal to install laravel socialite package

composer require laravel/socialite

Now open the file app.php in config/app.php

'providers' => [
       .................................................
 Laravel\Socialite\SocialiteServiceProvider::class,
];

  'aliases' => [
             ..................................................................
Socialite' => \Laravel\Socialite\Facades\Socialite::class,
];

Now open service.php in config/service.php

    'google' => [
        'client_id'     => env('GMAIL_CLIENT_ID'),
        'client_secret' => env('GMAIL_CLIENT_SECRET'),
        'redirect'      => env('GMAIL_URL'),
    ],

This will be used by the socialite driver so do not miss to add this.

Go to .env file** add the following lines of code

GMAIL_CLIENT_ID = xxxxxxxxxxx
GMAIL_CLIENT_SECRET = xxxxxxxxxx
GMAIL_URL = xxxxxxxxxx

4. Create 2 routes as follows

route::get('/social-login/{provider}',[App\Http\Controllers\SocialLoginController::class,'social_login']);

This route we will using in the html file to redirect the user to the OAuth provider.

route::get('/social-login/{provider}/callback',[App\Http\Controllers\SocialLoginController::class,'social_callback']);

This route is used for receiving the callback from the provider after authentication.

5.Create a separate controller using below command. type the command in terminal inside your project directory

php artisan make:controller SocialLoginController

After creating the controller open the controller in Http/Controllers/SocialLoginController.php and add the following code

    public function social_login($provider){
        return Socialite::driver($provider)->redirect();
    }

    public function social_callback($provider){
        $userSocial =   Socialite::driver($provider)->stateless()->user();
        $users       =   User::where(['email' => $userSocial->getEmail()])->first();
        if($users){
            Auth::login($users);
            Auth::login(Auth::user(), true);
            return redirect('/home');
        }else{
            $user = User::create([
                'name'          => $userSocial->getName(),
                'email'         => $userSocial->getEmail(),
                'provider_id'   => $userSocial->getId(),
                'provider'      => $provider,
            ]);         return redirect()->route('home');
        }
    }

You can create additional 2 columns provider_id and provider to track the user sign-in activity.

1. Now the login.blade.php provided by the laravel or your custom login add a tag

   <a  <a href="{{url('social-login/google')}}" class="btn btn-block">Sign In Gmail</a>
   

I will explain about how to get the google credentials for this in another blog. And also by adding few lines of code to this we can see how to login using Github.
