Recursive directory creation is expensive request-wise. Multiplestatrequests are made (totalling the depth of the path that exists, +1) to detect what parts of the path already exist, until finding a segment that doesn't exist - where it then only requests thecreationmethod. For example, a ...
exports 加载模块: var app = require('./app.js') 入口文件: package.json > main = index.js(默认) 模块缓存: 第一次加载某个模块时,Node会缓存该模块。以后再加载该模块,就直接从缓存取出该模块的module.exports属性。 加载机制: 输入的是被输出的值的拷贝。也就是说,一旦输出一个值,模块内部的变化就...
