Try running npm install jquery --save inside the assets folder, then adding jquery to the app.js as import jquery from "jquery".

Ok. I made it work.

For other. If you have vendor files in your vendor folder, add the dependencies directly into these files at the top part.
After that, just add the main vendor files directly to app.js

Hope this helps some one.

Thanks for your quick answer !

I did that and I managed to get jquery working if I comment the lines of the vendor files.

When I add the app.min vendor I get an error at the end of that file

“$(document).ready((function(){App.init()}));”

So by removing that final part of the file, the error on the console log disappears.

But by adding the other vendor file: vendor.min an other issue arises:

vendor.min.js:6 Uncaught ReferenceError: jQuery is not defined
at vendor.min.js:6:102430
at vendor/theme/js/vendor.min.js (vendor.min.js:6:102430)
at __require (app.js:27:46)
at app.js:35:8
at app.js:32:5

When I follow the error on the source files I get to this part of the code:

t(jQuery)}((function(t){“use strict”;t.ui=t.ui||{},t.ui.versio

Any idea of how I could make these vendor files work??

Now my app.js file looks like this:

import jQuery from “jquery”

window.jQuery = jQuery
window.$ = jQuery
$ = jQuery;

import “…/vendor/theme/js/app.min”
import “…/vendor/theme/js/vendor.min”

Thanks !
