Updated Article and Source Code - www.ultimateakash.com
composer remove tymon/jwt-auth
composer dump-autoload
then install
composer require tymon/jwt-auth:dev-develop --prefer-source
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
php artisan jwt:secret
Route::post('login', 'ApiController#login');
Route::post('register', 'ApiController#register');
Route::group(['middleware' => 'auth.jwt'], function () {
Route::get('logout', 'ApiController#logout');
Route::get('user', 'ApiController#getAuthUser');
});
?php
namespace App;

You may considerate to use Laravel Passport
From the laravel official docs: https://laravel.com/docs/5.8/passport
Laravel makes API authentication a breeze using Laravel Passport, which provides a full OAuth2 server implementation for your Laravel application in a matter of minutes. Passport is built on top of the League OAuth2 server that is maintained by Andy Millington and Simon Hamp.
Indeed since the library is maintained by the creator of Laravel, it will be more up-to-date and stable for Laravel than other concurrent libraries.
