Redirect to homepage if route doesnt exist in Laravel 5

/** Redirect 404's to home
*****************************************/
App::missing(function($exception)
{
    // return Response::view('errors.missing', array(), 404);
    return Redirect::to('/');
}); 

I have this code in my routes.php file. I am wondering how to redirect back to the home page if there is a 404 error. Is this possible?

For that, you need to do add few lines of code to render method in app/Exceptions/Handler.php file which looks like this:

public function render($request, Exception $e)
    {
        if($this->isHttpException($e))
        {
            switch ($e->getStatusCode()) 
                {
                // not found
                case 404:
                return redirect()->guest('home');
                break;

                // internal error
                case '500':
                return redirect()->guest('home');
                break;

                default:
                    return $this->renderHttpException($e);
                break;
            }
        }
        else
        {
                return parent::render($request, $e);
        }
    }
