Nodejs Uncaught ReferenceError: $ is not defined after var jQuery = require('jquery');

Question

I installed jQuery and it is not my question:

npm install jquery

I try to include jQuery library into my page like this:

var jQuery = require('jquery'); or
import jQuery from "jquery";

and get in Chrome console:

Uncaught ReferenceError: $ is not defined

How can I overcome it?

Answer 1

You have to use:

var $ = require('jquery');

or

import $ from 'jquery';

Answer 2

In my cases the following works well:

global.jQuery   = require('jquery');
global.$        = global.jQuery;

or if you prefer "window" or it is obviously present, then:

typeof window !== "undefined" ? window : this;
window.jQuery   = require('jquery');
window.$        = window.jQuery;
