Join For FreeNode.js is really handy as an interactive shell for JavaScript. Alas, there is no simple command for loading source code from an external file. This post describes a work-around.

exports.foo = function() {
console.log("Hello world!");

> t.foo()
Hello world!
Node caches modules. Thus, if the source file changes, you need to clear the module cache and re-require the module:
> module.moduleCache = {};
> t = require("./test");
