基於requirejs的vue2項目 (三)

這裏是打包篇

使用的是requirejs的r.js進行打包

思路是,經過entrance.js裏面的require.config進行項目的初打包

由於router.js和store.js裏面的引用是動態生成的,因此r.js沒法對其進行處理,這裏咱們用到了nodejs來進行文件整合

具體看代碼

node2build.js

var fs = require('fs')
var cp = require('child_process')
var __config__ = require('./../dist/config')
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,
  baseUrl: './',
  dir: '../' + todir,
