Usage example

In config/steam-auth.php:

return [

    /*
     * Redirect URL after login
     */
    'redirect_url' => '/auth/steam/handle',
    /*
     * Realm override. Bypass domain ban by Valve. 
     * Use alternative domain with redirection to main for authentication (banned by valve).
     */
    // 'realm' => 'redirected.com',
    /*
     *  API Key (set in .env file) [http://steamcommunity.com/dev/apikey]
     */
    'api_key' => env('STEAM_API_KEY', ''),
    /*
     * Is using https?
     */
    'https' => false,
];

In routes/web.php:

Route::get('auth/steam', 'AuthController@redirectToSteam')->name('auth.steam');
Route::get('auth/steam/handle', 'AuthController@handle')->name('auth.steam.handle');

Note: if you want to keep using Laravel's default logout route, add the following as well:

Route::post('logout', 'Auth\LoginController@logout')->name('logout');

In AuthController:

namespace App\Http\Controllers;

use Invisnik\LaravelSteamAuth\SteamAuth;
use App\User;
use Auth;

class AuthController extends Controller
{
    /**
     * The SteamAuth instance.
     *
     * @var SteamAuth
     */
    protected $steam;

    /**
     * The redirect URL.
     *
     * @var string
     */
    protected $redirectURL = '/';

    /**
     * AuthController constructor.
     * 
     * @param SteamAuth $steam
     */
    public function __construct(SteamAuth $steam)
    {
        $this->steam = $steam;
    }

    /**
     * Redirect the user to the authentication page
     *
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
     */
    public function redirectToSteam()
    {
        return $this->steam->redirect();
    }

    /**
     * Get user info and log in
     *
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
     */
    public function handle()
    {
        if ($this->steam->validate()) {
            $info = $this->steam->getUserInfo();

            if (!is_null($info)) {
                $user = $this->findOrNewUser($info);

                Auth::login($user, true);

                return redirect($this->redirectURL); // redirect to site
            }
        }
        return $this->redirectToSteam();
    }

    /**
     * Getting user by info or created if not exists
     *
     * @param $info
     * @return User
     */
    protected function findOrNewUser($info)
    {
        $user = User::where('steamid', $info->steamID64)->first();

        if (!is_null($user)) {
            return $user;
        }

        return User::create([
            'username' => $info->personaname,
            'avatar' => $info->avatarfull,
            'steamid' => $info->steamID64
        ]);
    }
}

Should you wish to use a login redirection URL that is differant from the one you specified in the config

// Inside your controller login method
$this->steam->setRedirectUrl(route('login.route'));

...

return $this->steam->redirect();

If you need another steamID you can use another package to convert the given steamID64 to another type like xPaw/SteamID.
