Require a node_module from within a subfolder

Question

So I have some node.js files

/folder/app.js
/folder/node_modules/moduleIwanttoload
/folder/subfolder/file.js

how do I require moduleIwanttoload from file.js?

Answer 1

you can use subfolder files like this into app.js

var file = require('./subfolder/file.js');

and in the folder of node-modules you can just use it like

var moduleIwanttoload = require("moduleIwanttoload");

Answer 2

If the module you want to load is a dependency contained in "node_modules" you can simply use

require("moduleIwanttoload")

Node JS will trace the directory tree down to the first folder in which it finds a "node_modules" directory and looks for the given dependency in it.
