1. wrap up a module using module.exports, name the file to a.js
var fun1=function(){ var stylus = require('stylus'); this.hi=function(){ console.log('hi'); } } fun1.prototype.hello=function(){ console.log("abcdefg"); } module.exports=fun1;
2. load module using rquire function
var a=require('./a');
var instanceA=new a();
instanceA.hi();
instanceA.hello();
