New in Symfony 4.1: Ajax improvements

April 19, 2018 Avatar of Javier Eguiluz Javier Eguiluz

A simpler way to test Ajax requests

Contributed by
Hamza Amrouche
in #26381.

The BrowserKit component used in Symfony functional tests provides lots of utilities to simulate the behavior of a web browser. In Symfony 4.1 we've added a new utility to make Ajax requests simpler: xmlHttpRequest().

This method works the same as the current request() method and accepts the same arguments, but it adds the required HTTP_X-REQUESTED-WITH header automatically so you don't have to do that yourself:

// Before
$crawler = $client->request('GET', '/some/path', [], [], [
    'HTTP_X-Requested-With' => 'XMLHttpRequest',
]);

// After
$crawler = $client->xmlHttpRequest('GET', '/some/path');

Improved the Ajax panel in the debug toolbar

The first minor but noticeable change is that the link to the Ajax request profile has been moved to the first column of the table, so it's easier to click on it.

In addition, when the Ajax request results in an exception (HTTP status of 400 or higher) the profiler link points to the exception profiler panel instead of the default request/response panel:

In any case, the biggest new feature of the Ajax panel is that requests now display their duration in real-time, so you always know which requests are still pending to finish:

Live AJAX updates are great! Would love to see DB query counter increase dynamically, too. So I know if my AJAX is causing 1,000,000 DB calls per load :)

Thanks \o/

Note: There's a typo in the first contribution: "HTTP_X_REQUESTED_WITH" should be "HTTP_X-REQUESTED-WITH" like in the code block.
