    AJAX check session expired


Create a middleware

php artisan make:middleware AjaxSessionExpiredMiddleware

Open the AjaxSessionExpiredMiddleware and add following code:

<?php

namespace App\Http\Middleware;

use Closure;

class AjaxSessionExpiredMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if ($request->ajax() && \Auth::guest()) {
            return response()->json(['message' => 'Session expired'], 403);
        }

        return $next($request);
    }
}

Open Kernel.php inside app/Http directory and add following line in routeMiddleware property:

'ajax-session-expired' => \App\Http\Middleware\AjaxSessionExpiredMiddleware::class,

Open TodoListsController and add following code:

class TodoListsController extends Controller
{
    public function __construct()
    {
        // check if session expired for ajax request
        $this->middleware('ajax-session-expired');

        // check if user is autenticated for non-ajax request
        $this->middleware('auth');
    }

    // ..
}
