Laravel Social Login using Socialite

Hello everyone, welcome back ! Here am going to tell how to implement social logins in your laravel applications using Socialite package. I will cover most popular social sites like Facebook, Google +, Twitter and Github. Lets get started.

First you need to register at those social networks, get some keys like client_id, client_secret.which are used to connect your laravel app with those networks.

• Facebook Login
• Google + Login
• Twitter Login
• Github Login

Installing Socialite :

Socialite is a laravel package where authentication with different social network providers is a breeze.

Install it using composer by running the following line in root of you project,

composer require laravel/socialite

After installing Socialite package, you need to register its service provider. In configurations file config/app.php add the following lines,

'providers' => [
    // Other service providers...

Laravel\Socialite\SocialiteServiceProvider::class,
],

You also need to add its facade in aliases array,

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

Now Socialite is all set up and you are ready to implement social login in your laravel apps. I will go through each of them mentioned above.

Facebook Login using Socialite :

• Register yourself at developers.facebook.com.
• In the top right corner, if you never developed a facebook app before click 'Create App' button or else in select 'Create App' option in the drop down below your previously created apps.

• Fill your app details like app name, contact email and category,

• After creating a sample app, In you setting section, you need to fill details like 'App Domain/s' and 'Website URL' where you app is used. I just set them to local host for now.

• Now we use those 'App Id' and 'App Secret' as CLIENT_ID and CLIENT_SECRET in you app configuration file. We store those details in .env file and reference them in config/services.php

in you .env file,

FB_CLIENT_ID = Your FB App Id
FB_CLIENT_SECRET = Your FB App Secret
FB_REDIRECT = 'http://localhost:8000/callback/facebook'

and in your config/services.php file

'facebook' => [ 
                'client_id' => env ( 'FB_CLIENT_ID' ),
                'client_secret' => env ( 'FB_CLIENT_SECRET' ),
                'redirect' => env ( 'FB_REDIRECT' ) 
        ],

• Now i will just add simple link which calls facebook login page,

<a href="redirect/facebook">Login in with Facebook</a>

Note : The following routes and controller functions are similar for all the calls, we only set the client_id and client_secret in .env and config/services.php. For remaining services google +, twitter, github the routes and function are same.

Now it will call the route,

Route::get ( '/redirect/{service}', 'SocialAuthController@redirect' );

the redirect function,

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

After successful login, it will redirect to the url we have set as callback url, I have set it as http://localhost:8000/callback/facebook

the route,

Route::get ( '/callback/{service}', 'SocialAuthController@callback' );

callback function,

public function callback($service) {
        $user = Socialite::with ( $service )->user ();
        return view ( 'home' )->withDetails ( $user )->withService ( $service );
    }

Here we get some details like username, email and gender and display them.

@if($service == 'facebook')
<div class="title m-b-md">
    Welcome {{ $details->user['name']}} ! <br> Your email is : {{
    $details->user['email'] }} <br> You are {{ $details->user['gender'] }}.
</div>
@endif

That's it, folks. We have successfully logged into facebook using Socialite.
