基於requirejs的vue2專案 (三)

這裡是打包篇

使用的是requirejs的r.js進行打包

思路是,通過entrance.js裡面的require.config進行專案的初打包

因為router.js和store.js裡面的引用是動態生成的,所以r.js無法對其進行處理,這裡我們用到了nodejs來進行檔案整合

具體看程式碼

node2build.js

var fs = require(`fs`)
var cp = require(`child_process`)

var fromdir = (process.argv.length >= 3
  ? process.argv[2]
    ? process.argv[2]
    : ``
  : `dist`)
var todir = (process.argv.length >= 4
  ? process.argv[3]
    ? process.argv[3]
    : ``
  : `pack`)
var base = {
  appDir: `../` + fromdir,
