浅析webpack源码之Stat.js粗解(十）

Andrman / 3484人阅读

摘要：从出来接着我们看大法，打印一下感觉之前所以的对象都放在了一个合集里，给人而全的感觉里面主要含有一个对象，，输出的，等给每次打包一个值，代表唯一性天啊

从compilation出来
接着我们看

const stats = new Stats(compilation);
Stats.js

log大法，打印一下 stats

let Stats = {
  compilation:{

  endTime: undefined }

感觉之前所以的对象都放在了一个合集里，给人而全的感觉

里面主要含有一个对象
inputFileSyste，options，输出的outputOptions，dependencyFactories等
给每次打包一个hash值，代表唯一性

天啊
