From Symfony 4, I need to generate dynamicals url path of my controller (controller who need, in the futur, some parameters) from javascript.

After some google searches I found and installed the jsrouting-bundle via a simple composer require friendsofsymfony/jsrouting-bundle (I executed the recipe)

I include theses lines in my twig file :

<script src=" asset('bundles/fosjsrouting/js/router.js') "></script>
<script src=" path('fos_js_routing_js', callback: 'fos.Router.setData' ) "></script>
<script src="build/js/global.js"></script>

When I load my page, no javascript errors appeared.

So, I created this very simple symfony controller (for an AJAX call) :

/**
 * @Route("/API/test", name="ajax_test")
 */
public function test()
 $test = [
 'a' => 'foo',
 'b' => 'faa',
 ];
 return new JsonResponse($test);

And in my custom javascript script (global.js) , I tried this :

alert(Routing.generate('ajax_test'));

But when I load the page, I get this javascript error :

Error: The route "ajax_test" does not exist.

Why the route is not found ? Where is my mistake ?

Notes :

in the friendsofsymfony/jsrouting-bundle documentation , from the when I executed the command bin/console assets:install --symlink web I get the error The target directory "web" does not exist.. So, I executed simply bin/console assets:install --symlink

If I go to the "http://localhost/mywebsite/public/js/routing?callback=fos.Router.setData", I get /**/fos.Router.setData("base_url":"/mywebsite/public","routes":,"prefix":"","host":"localhost","port":"","scheme":"http");

I just add the option "expose" set to true in annotations of my controller like this :

/**
 * @Route("/API/test", name="ajax_test", options="expose"=true)
 */
public function test()
 $test = [
 'a' => 'foo',
 'b' => 'faa',
 ];
 return new JsonResponse($test);
