How to use npm jquery module?

Question

How should I requirethe jquery in node if I use it in multiple modules? Should I define it as a global or should I just use the require('jquery)` in every module I need it?

I am getting an error when trying to use the package.

TypeError: Object function ( w ) {             if ( !w.document ) {                 throw new Error( "jQuery requires a window with a document" );             }             return factory( w );         } has no method 'isArray' 

It looks like a bug in the current release as it should not check if I am running it in a browser according to the official documentation. This issue is also mentioned in another post. It works with version 1.8.3 as mentioned in one of the answers.

To use jquery in node, you need to have two separate node package installations.

1. jquery
2. jsdom to create a dummy window object which jquery can use.

Installation:

npm install jquery npm install jsdom 

In code:

var jsdom = require("jsdom").jsdom; global.$ = require('jquery/dist/jquery')(jsdom().createWindow()); 

Or, with newer versions of jsdom:

require("jsdom").env("", function(err, window) {     if (err) {         console.error(err);         return;     }      var $ = require("jquery")(window); }); 

Using global.$ will make the jquery object($) available globally in your project.
