[javascript] Trying to use fetch and pass in mode: no-cors

So if you're like me and developing a website on localhost where you're trying to fetch data from Laravel API and use it in your Vue front-end, and you see this problem, here is how I solved it:

  1. In your Laravel project, run command php artisan make:middleware Cors. This will create app/Http/Middleware/Cors.php for you.
  2. Add the following code inside the handles function in Cors.php:

    return $next($request)
        ->header('Access-Control-Allow-Origin', '*')
        ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
    
  3. In app/Http/kernel.php, add the following entry in $routeMiddleware array:

    ‘cors’ => \App\Http\Middleware\Cors::class
    

    (There would be other entries in the array like auth, guest etc. Also make sure you're doing this in app/Http/kernel.php because there is another kernel.php too in Laravel)

  4. Add this middleware on route registration for all the routes where you want to allow access, like this:

    Route::group(['middleware' => 'cors'], function () {
        Route::get('getData', 'v1\MyController@getData');
        Route::get('getData2', 'v1\MyController@getData2');
    });
    
  5. In Vue front-end, make sure you call this API in mounted() function and not in data(). Also make sure you use http:// or https:// with the URL in your fetch() call.
