基于requirejs的vue2项目 (三)

这里是打包篇

使用的是requirejs的r.js进行打包

思路是,经过entrance.js里面的require.config进行项目的初打包

由于router.js和store.js里面的引用是动态生成的,因此r.js没法对其进行处理,这里咱们用到了nodejs来进行文件整合

具体看代码

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,

// 这里是经过配置文件来组装配置信息对设置了同步的模板进行打包
