main

node-main

A very basic module that only runs code if the script is ran directly (And not required). It utilizes optimist for argument parsing. See this SO question for more information on how it works.

Usage

require('main')(function(argv) {
	// The code in here will only be executed if running from the CLI
	//
	// argv is the argv object that optimist produces, e.g.
	// require('optimist').argv;
});

Example

test.js

exports.foo = function() { return 'bar'; }

require('main')(function(argv) {
	console.log(exports.foo());
});

Running from the terminal:

$ node test.js
bar

Using the module from another script will not execute the code in main:

var test = require('./test');
console.log(test.foo()); // 'bar'
