Requiring CoffeeScript from Node.js application gives cannot find module error

Question

I'm trying to require a CoffeeScript file from a Node.js application but Node.js gives error Error: Cannot find module 'something'. What is the proper way to do this? If I compile the CoffeeScript code beforehand, it works but I don't want to do this.

test.js:

require('coffee-script').register();

require('something');

something.coffee:

console.log('Hello World!');

Console output:

> node test.js

module.js:340
    throw err;
          ^
Error: Cannot find module 'something'

@DaveNewton Well I found multiple answers suggesting this should be possible. See for example stackoverflow.com/a/4769079/2193958. — Scintillo

Why not try what it said there? I always have a watcher that's linting and compiling so I don't really know about on-demand compilation--sorry. — Dave Newton

It seems like you are trying to require() a file using the structure to require() a module.

If you require() something without giving require() a path to a file (absolute or relative), Node.js is going to look up for your module inside the /node_modules directory. You can read the documentation here.

Try requiring your module as a JavaScript file like this:

require('./something')

(and make sure './something' is the path from where you require the module to where the module is located in your app structure, or use an absolute path).
