Jquery error '$ is not a function' in Node.js
Question
I am getting the console error '$ is not a function' when using Jquery with Jsdom. I am using the latest Jquery version 3.3.1 and Jsdom 13.2.0. I am also using Browserify in order to utilize require.
main.js
var jsdom = require('jsdom');
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM('')).window;
global.document = document;
var $ = jQuery = require('jquery')(window);
$("body").click(function() {
$("#name-tag").fadeOut("slow", function() {
// Animation complete.
});
});
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta
name="viewport"
content="width=device-width, initial-scale = 1.0, maximum-scale=1.0, user-scalable=no"

<script src="js/bundle.js"></script>
</head>
<body>
<div id="name-tag">
<h1>Hello World</h1>
</div>
</body>
</html>

Get rid of (window) after require('jquery') , so it should just be:
var $ = jQuery = require('jquery');
What you've written is redefining $ and jQuery as if you'd done:
jQuery = require('jquery');
var $ = jQuery = jQuery(window);
BTW, you can't declare two variables by chaining assignments like that. Only the first variable is being declared locally, the second one is an assignment without a declaration. If you want to declare two variables and given them the same value, do it in two steps:
var $, jQuery;
$ = jQuery = require('jquery');
