How I can handle my 404 custom page (and possibly other errors)?

I just tried in routing part to add

GET /@codes /WebController->error

    You don't have to define a route for this. F3 will automatically generate a 404 status code for any non-defined route.

    If you want to define a custom error page, you need to set the ONERROR variable.

    Here's a quick example:

    $f3->route('GET /','App->home');
$f3->set('ONERROR',function($f3){
  echo \Template::instance()->render('error.html');
});
$f3->run();

    with error.html defined as:

    <!DOCTYPE html>
<head>
<title>{{@ERROR.text}}</title>
</head>
<body>
  <h1>{{@ERROR.text}}</h1>
  <p>Error code: {{@ERROR.code}}</p>
</body>
</html>

    Now if you call any non-defined route like /foo, the template error.html will be rendered with a 404 status code.

    NB: this works for other error codes. Other error codes are triggered by F3 or your application with the command $f3->error($status), $status being any valid HTTP status code (404, 500, 403, etc...)
