How do I catch exceptions / missing pages in Laravel 5?

Question

In Laravel 5, App::missing and App::error is not available, so how do your catch exceptions and missing pages now?

I could not find any information regarding this in the documentation.

In Laravel 5 you can catch exceptions by editing the render method in app/Exceptions/Handler.php.

If you want to catch a missing page (also known as NotFoundException) you would want to check if the exception, $e, is an instance of SymfonyComponentHttpKernelExceptionNotFoundHttpException.

public function render($request, Exception $e) {
    if ($e instanceof SymfonyComponentHttpKernelExceptionNotFoundHttpException)
        return response(view('error.404'), 404);

    return parent::render($request, $e);
}

With the code above, we check if $e is an instanceof of SymfonyComponentHttpKernelExceptionNotFoundHttpException and if it is we send a response with the view file error.404 as content with the HTTP status code 404.

This can be used to ANY exception. So if your app is sending out an exception of AppExceptionsMyOwnException, you check for that instance instead.

public function render($request, Exception $e) {
    if ($e instanceof AppExceptionsMyOwnException)
        return ''; // Do something if this exception is thrown here.

    if ($e instanceof SymfonyComponentHttpKernelExceptionNotFoundHttpException)
        return response(view('error.404'), 404);

    return parent::render($request, $e);
}
