webpack encore fetch in symfony 5

I’m learning to use webpack Encore

I would like to know if it is possible to use the ‘path’ function to call a route via ajax


    .setOutputPath ('public / build /')
    .setPublicPath ('/ build')
    .addEntry ('app', './assets/js/app.js') 
    .addEntry ('ajax', './assets/js/ajax.js')

I created a second entry which imports all ajax calls


import 'bootstrap'; // adds functions to jQuery

import articleShow './myAjax/articleShow';

myAjax > articleShow.js

is it possible to use the path function ?

        let formData = new FormData();

        formData.append("folder", folder);
        formData.append("id", id);

        **var urlAjax = "{{ path('showArticle') }}";** (pb)!!!
        //var urlAjax = "https://localhost:8000/article/show";
        fetch(urlAjax, {
            method: 'POST',
            body: formData
            .then(function (response) {
                return response.json();
            .then(function (message) {


    * @Route("/article/show", name="showArticle")
    public function showArticle(....) {

question 1: Is it possible to use the ‘path’ function with webpack encore?

question 2: is my approach correct? if no, do you have a suggestion with a concrete example because i have hardly found anything as documentation.

thanks for your help.
