1. Node.js的模块载入方式与机制
Node.js中模块可以通过文件路径或名字获取模块的引用。模块的引用会映射到一个js文件路径，除非它是一个Node内置模块。Node的内置模块公开了一些常用的API给开发者，并且它们在Node进程开始的时候就预加载了。
其它的如通过NPM安装的第三方模块（third-party modules）或本地模块（local modules），每个模块都会暴露一个公开的API。以便开发者可以导入。如
var mod = require('module_name')
此句执行后，Node内部会载入内置模块或通过NPM安装的模块。require函数会返回一个对象，该对象公… Read More
