CORS (Access-Control-Allow-Origin) on Laravel

I created an application in AngularJS and I'm trying to make calls to the Laravel API:

• MyApp (AngularJS): http://localhost:8080/
• API (Laravel Boilerplate): http://localhost:8000/

I use Laravel API Boilerplate (JWT Edition) to API.

But I get this error in the browser console:

XMLHttpRequest cannot load http://localhost:8000/api/auth/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

I tried to apply the cors middleware (barryvdh/laravel-cors) in api_routes.php but the error remains. I am using the Angle Satellizer to login.

api_routes.php:

<?php

$api = app('Dingo\Api\Routing\Router');

$api->version('v1', ['middleware' => 'cors'], function ($api) {

    $api->post('auth/login', 'App\Api\V1\Controllers\AuthController@login');
    $api->post('auth/signup', 'App\Api\V1\Controllers\AuthController@signup');
    $api->post('auth/recovery', 'App\Api\V1\Controllers\AuthController@recovery');
    $api->post('auth/reset', 'App\Api\V1\Controllers\AuthController@reset');

    // example of protected route
    $api->get('protected', ['middleware' => ['api.auth'], function () {     
        return \App\User::all();
    }]);

    // example of free route
    $api->get('free', function() {
        return \App\User::all();
    });

});
