Question

I have a basic Node.js+socket.io app, and want to include coffee-script file. It was easy to include the file with

require('coffee-script');
items = require('./brain/items.coffee');

and it works – console.log throw debug info. But I couldn’t access variables, functions and other stuff from the file. Also in the compiled version of the imported file it looks so:

(function() {
  var a,run;
  a = 'ok';
  run = function() {
    return console.log('all-oik!');
  };
}).call(this);

so it looks for me like it run in its own scope and really not accessible from the other script (am I wrong? I’m not so good with advanced JS).

How could I work around this and take cofffee content from the main app?

PS: main app is a plain .js file, not coffee-script, if it matters.

Answer 1

This is no coffee-script specific problem. Have you tried importing functions from a normal js file in your main file? How did that go?

You can read one of many handy intros: http://openmymind.net/2012/2/3/Node-Require-and-Exports/

What you’ll discover is that node’s require uses commonjs modules, and to make something available outside a module, you need to assign it to the module.exports variable.

so in your case: (in coffee-script)

module.exports.a = 'ok'
module.exports.run = () ->
  return console.log 'all-oik!'
