vue 打包dist 文件太大,怎么解决?
下面是我进行npm run dist 的webpack,但是打包出来的sendMessageQj.js
文件有7MB多,就是有几个组件,然后打包出来了,还有一个编辑器的源码,还可以再从这个文件里面添加插件进行体积优化吗?
const path = require('path')const webpack = require('webpack')
const utils = require('./utils')
var package = require('../package.json');
module.exports = {
entry: './plugins/install.js',
output: {
path: path.resolve(process.cwd(), `./libs@${package.version}`),
publicPath: '/dist/',
filename: 'sendMessageQj.js',
library: 'sendMessageQj', // library 指定的就是你使用 require 时的模块名,这里便是 require('BuriedPoint')
libraryTarget: 'umd', // libraryTarget 会生成不同 umd 的代码,可以只是 commonjs 标准的,也可以是指 amd 标准的,也可以只是通过 script 标签引入的
umdNamedDefine: true // 会对 UMD 的构建过程中的 AMD 模块进行命名。否则就使用匿名的 define。

用webpack-bundle-analyzer
检查下模块结构,合并冗余模块.
你这个看起来是一个插件,可以修改插件结构,改成一个core+N个功能模块的结构,然后每个功能模块拆分为单独js,core提供一个加载模块的功能.
使用时的伪代码
import Core from "sendMessageQj"Core.load('module-1');
Core.load('module-2');
Vue.use(Core);
