$ is not defined when installing jQuery in Rails via Webpack

Question

I\'m trying to install jQuery in Rails 6.0.0.rc1 via Webpack and I\'m not sure what I\'m missing but I\'m getting the error $ is not defined in the browser console

Answer 1

I've got what's missing.

In app/javascript/packs/application.js forgot to declare:

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

So jQuery keywords could be picked up.
