Hypervel Socialite

Introduction

In addition to typical, form based authentication, Hypervel also provides a simple, convenient way to authenticate with OAuth providers using Hypervel Socialite. Socialite currently supports authentication via Facebook, X, LinkedIn, Google, GitHub, GitLab, Bitbucket, and Slack.

Note

Although you can't install other community-driven adapters from Socialite Providers website, you can still easily migrate those adapters on your own.

Installation

To get started with Socialite, use the Composer package manager to add the package to your project's dependencies:

composer require hypervel/socialite

Configuration

Before using Socialite, you will need to add credentials for the OAuth providers your application utilizes. Typically, these credentials may be retrieved by creating a "developer application" within the dashboard of the service you will be authenticating with.

These credentials should be placed in your application's config/services.php configuration file, and should use the key facebook, x, linkedin-openid, google, github, gitlab, bitbucket, slack, or slack-openid, depending on the providers your application requires:

'github' => [
    'client_id' => env('GITHUB_CLIENT_ID'),
    'client_secret' => env('GITHUB_CLIENT_SECRET'),
    'redirect' => 'http://example.com/callback-url',
],

Note

If the redirect option contains a relative path, it will automatically be resolved to a fully qualified URL.

Authentication

Routing

To authenticate users using an OAuth provider, you will need two routes: one for redirecting the user to the OAuth provider, and another for receiving the callback from the provider after authentication. The example routes below demonstrate the implementation of both routes:

use Hypervel\Socialite\Facades\Socialite;

Route::get('/auth/redirect', function () {
    return Socialite::driver('github')->redirect();
});

Route::get('/auth/callback', function () {
    $user = Socialite::driver('github')->user();

    // $user->token
});

The redirect method provided by the Socialite facade takes care of redirecting the user to the OAuth provider, while the user method will examine the incoming request and retrieve the user's information from the provider after they have approved the authentication request.

Authentication and Storage

Once the user has been retrieved from the OAuth provider, you may determine if the user exists in your application's database and authenticate the user. If the user does not exist in your application's database, you will typically create a new record in your database to represent the user:

use App\Models\User;
use Hypervel\Support\Facades\Auth;
use Hypervel\Socialite\Facades\Socialite;

Route::get('/auth/callback', function () {
    $githubUser = Socialite::driver('github')->user();

    $user = User::updateOrCreate([
        'github_id' => $githubUser->id,
    ], [
        'name' => $githubUser->name,
        'email' => $githubUser->email,
        'github_token' => $githubUser->token,
        'github_refresh_token' => $githubUser->refreshToken,
    ]);

    Auth::login($user);

    return redirect('/dashboard');
});

Note

For more information regarding what user information is available from specific OAuth providers, please consult the documentation on retrieving user details.

Access Scopes

Before redirecting the user, you may use the scopes method to specify the "scopes" that should be included in the authentication request. This method will merge all previously specified scopes with the scopes that you specify:

use Hypervel\Socialite\Facades\Socialite;

return Socialite::driver('github')
    ->scopes(['read:user', 'public_repo'])
    ->redirect();

You can overwrite all existing scopes on the authentication request using the setScopes method:

return Socialite::driver('github')
    ->setScopes(['read:user', 'public_repo'])
    ->redirect();

Slack Bot Scopes

Slack's API provides different types of access tokens, each with their own set of permission scopes. Socialite is compatible with both of the following Slack access tokens types:

Bot (prefixed with xoxb-)
User (prefixed with xoxp-)

By default, the slack driver will generate a user token and invoking the driver's user method will return the user's details.

Bot tokens are primarily useful if your application will be sending notifications to external Slack workspaces that are owned by your application's users. To generate a bot token, invoke the asBotUser method before redirecting the user to Slack for authentication:

return Socialite::driver('slack')
    ->asBotUser()
    ->setScopes(['chat:write', 'chat:write.public', 'chat:write.customize'])
    ->redirect();

In addition, you must invoke the asBotUser method before invoking the user method after Slack redirects the user back to your application after authentication:

$user = Socialite::driver('slack')->asBotUser()->user();

When generating a bot token, the user method will still return a Hypervel\Socialite\Two\User instance; however, only the token property will be hydrated. This token may be stored in order to send notifications to the authenticated user's Slack workspaces.

Optional Parameters

A number of OAuth providers support other optional parameters on the redirect request. To include any optional parameters in the request, call the with method with an associative array:

use Hypervel\Socialite\Facades\Socialite;

return Socialite::driver('google')
    ->with(['hd' => 'example.com'])
    ->redirect();

Warning

When using the with method, be careful not to pass any reserved keywords such as state or response_type.

Retrieving User Details

After the user is redirected back to your application's authentication callback route, you may retrieve the user's details using Socialite's user method. The user object returned by the user method provides a variety of properties and methods you may use to store information about the user in your own database.

Differing properties and methods may be available on this object depending on whether the OAuth provider you are authenticating with supports OAuth 1.0 or OAuth 2.0:

use Hypervel\Socialite\Facades\Socialite;

Route::get('/auth/callback', function () {
    $user = Socialite::driver('github')->user();

    // OAuth 2.0 providers...
    $token = $user->token;
    $refreshToken = $user->refreshToken;
    $expiresIn = $user->expiresIn;

    // OAuth 1.0 providers...
    $token = $user->token;
    $tokenSecret = $user->tokenSecret;

    // All providers...
    $user->getId();
    $user->getNickname();
    $user->getName();
    $user->getEmail();
    $user->getAvatar();
});

Retrieving User Details From a Token

If you already have a valid access token for a user, you can retrieve their user details using Socialite's userFromToken method:

use Hypervel\Socialite\Facades\Socialite;

$user = Socialite::driver('github')->userFromToken($token);

If you are using Facebook Limited Login via an iOS application, Facebook will return an OIDC token instead of an access token. Like an access token, the OIDC token can be provided to the userFromToken method in order to retrieve user details.

Stateless Authentication

The stateless method may be used to disable session state verification. This is useful when adding social authentication to a stateless API that does not utilize cookie based sessions:

use Hypervel\Socialite\Facades\Socialite;

return Socialite::driver('google')->stateless()->user();
