My Node.js modules these days

example.js

// assets
// first installed modules
var util = require('util')              
var assert = require('assert')          
var whatever = require('whatever')      
// then local
var foo = require('./foo')              
var bar = require('./bar')              

// main export
module.exports = the_exported_function  

module.exports.extra = extra            
module.exports.other = other            


var ENABLE_BUGS = false                 
  , MODE = 'production'                 

function the_exported_function() {      
}                                       

function extra() {                      
}                                       

function other() {                      
}                                       


function main() {                       
}                                       

// IF RUN DIRECTLY via node <filename>.js
if(require.main === module) {
  // do stuff here 
}
// otherwise its a module
else {
  module.exports = the_exported_function
}
