Vue项目分包打包配置(包含dev)完整过程
前言
今天领导要求支援某项目的分包配置,emmm,在参考了公司其他项目的分包操作后,依葫芦画瓢,中间也踩了好几个坑,简单记录下过程。
一、拉代码、安装依赖
哈哈哈,上来就踩坑了,我拉了代码后,直接哐哐整,然后一堆依赖报错,我才发现,同事新增了依赖包,我并不知道,然后就乖乖安装依赖吧。此处要特别强调一下,***没有cross-env 这个依赖的,记得要安装一下,没有cross-env 这个依赖的,记得要安装一下,没有cross-env 这个依赖的,记得要安装一下,***重要的事情说三遍,不安的话分包整不了。shell命令贴上了:npm install --save-dev cross-env 安装成功后 package.json里面会多"cross-env": “^7.0.3”,配置项,那就对了.如果实在不行,要不然你就试试全局安装吧,npm install -g cross-env,反正全局安装肯定是可以的,
二、配置环境变量
这个也是个坑坑啊,我要改的项目没有配置环境变量,我一开始没发现,后来死活不加载不同环境下对应的路由,才发现是这的坑。还有打包目录名字可配可不配,不过建议配置上。
vue.config.js中如下配置
let projectName = process.env.PROJECT_NAME || "All"; //获取名称 module.exports = { publicPath: './', outputDir: "dist/" + projectName + "/", //打包后的项目目录名称,建议这样修改 productionSourceMap: false, lintOnSave: false, devServer: { //自己公司项目自己配置哈 }, chainWebpack: config => { // 设置环境变量 config.plugin("define").tap(args => { args[0]["process.env"].PROJECT_NAME = JSON.stringify( process.env.PROJECT_NAME ); return args; }); } }
三、拆路由
把项目中router.js中的要分包的路由分别拆到不同的文件中,例如我图中就拆了前后9个,后续不同的打包命令,就会加载这九个文件中的对应的路由。此处有个疑问,就是能不能拆分子路由的问题,大家可以试试。我是把一个模块的父子路由打包带走的。此处就放两个文件路由大家参考一下
//sign.js export default[ { path: "/main", name: "main", meta: { cachePage: true }, component: () => import("@/views/main/main.vue"), children: [ { path: "/other", name: "other", component: () => import("@/views/login/other"), }, /* 贷款签约 */ { path: "/loanSigning", name: "loanSigning", meta: { cachePage: true, showMain: true }, component: () => import("@/views/loanSigning/index"), }, { path: "/loanSigningEdit", name: "loanSigningEdit", meta: { showBack: true }, component: () => import("@/views/loanSigning/loanSigningEdit"), }, { path: "/loanSigningRead", name: "loanSigningRead", meta: { showBack: true }, component: () => import("@/views/loanSigning/loanSigningRead"), }, ] } ] ```javascript ```javascript //track.js export default[ { path: "/main", name: "main", meta: { cachePage: true }, component: () => import("@/views/main/main.vue"), children: [ { path: "/other", name: "other", component: () => import("@/views/login/other"), }, /* 轨迹视图 */ { path: "/trackView", name: "mobileMarketing", meta: { cachePage: true, showMain: true }, component: () => import("@/views/trackView/index"), }, { path: "/trackViewAdd", name: "trackViewAdd", meta: { showBack: true }, component: () => import("@/views/trackView/trackViewAdd"), }, ] } ]
四、配置config.js文件
config.js主要是判断不同的环境下,加载刚才拆的那九个不同的路由
//config.js let options={ "routersName":[],//路由文件名列表 "menuFlag":"",//显示的功能列表标识 } if(process.env.PROJECT_NAME=='All'){ options.menuFlag="All" options.routersName=[ ...require("@/plugins/vueRouter/all.js").default ] }else if(process.env.PROJECT_NAME=='potential'){ options.menuFlag="potential" options.routersName=[ ...require("@/plugins/vueRouter/potential.js").default, ] }else if(process.env.PROJECT_NAME=='mobile'){ options.menuFlag="mobile" options.routersName=[ ...require("@/plugins/vueRouter/mobile.js").default, ] }else if(process.env.PROJECT_NAME == 'credit'){ options.menuFlag="credit" options.routersName=[ ...require("@/plugins/vueRouter/credit.js").default, ] }else if(process.env.PROJECT_NAME == 'loan'){ options.menuFlag="loan" options.routersName=[ ...require("@/plugins/vueRouter/loan.js").default, ] }else if(process.env.PROJECT_NAME == 'sign'){ options.menuFlag="sign" options.routersName=[ ...require("@/plugins/vueRouter/sign.js").default, ] }else if(process.env.PROJECT_NAME == 'track'){ options.menuFlag="track" options.routersName=[ ...require("@/plugins/vueRouter/track.js").default, ] }else if(process.env.PROJECT_NAME == 'approval'){ options.menuFlag="approval" options.routersName=[ ...require("@/plugins/vueRouter/approval.js").default, ] }else if(process.env.PROJECT_NAME == 'main'){ options.menuFlag="main" options.routersName=[ ...require("@/plugins/vueRouter/main.js").default, ] } export default options
五、修改router.js
//router.js import Vue from "vue"; import VueRouter from "vue-router"; import store from "@/plugins/vuex/store"; import config from "../../config" //这个路径要以你的项目路径来哈,自行修改 Vue.use(VueRouter); let routes=[ { path: "/", name: "index", redirect: "/login" }, { path: "/login", name: "login", meta: { cachePage: true }, component: () => import("@/views/login/login.vue"), } //要拆包的那些路径,都要删了哈,不然分包就分个寂寞啦!!!!!!!! ] routes=[...routes,...config.routersName] //路由表合并 console.log(routes,'routerjs中本身的路由') console.log(config,'config中获取的路由') console.log(process.env.PROJECT_NAME,'环境变量') const router = new VueRouter({ // mode: 'hash', base: process.env.BASE_URL, routes }); //如果你的项目中有其他的逻辑 再自行添加哈 // ...........其他业务逻辑代码
在合并路由表那块 ,我本来想试试子路由单独拿出来,父路由还放在router.js中的,但是我感觉往children里面塞,也不够优雅,就索性把 path: "/main"这个父路由和children里的子路由都拆走了
六、配置package.json
终于到了这一步,临门一脚了,这一步就是配置shell命令了
为了方便复制,我把package.json里scripts里面的命令代码给大家贴出来,其他的配置应该不用我贴了吧
//package.json中的命令 "scripts": { "dev": "set NODE_OPTIONS=--openssl-legacy-provider && cross-env PROJECT_NAME=All vue-cli-service serve", "dev:main": "cross-env PROJECT_NAME=main vue-cli-service serve", "dev:potential": "cross-env PROJECT_NAME=potential vue-cli-service serve", "dev:mobile": "cross-env PROJECT_NAME=mobile vue-cli-service serve", "dev:credit": "cross-env PROJECT_NAME=credit vue-cli-service serve", "dev:loan": "cross-env PROJECT_NAME=loan vue-cli-service serve", "dev:sign": "cross-env PROJECT_NAME=sign vue-cli-service serve", "dev:track": "cross-env PROJECT_NAME=track vue-cli-service serve", "dev:approval": "cross-env PROJECT_NAME=approval vue-cli-service serve", "build": "cross-env PROJECT_NAME=All vue-cli-service build", "build:potential": "cross-env PROJECT_NAME=potential vue-cli-service build", "build:main": "cross-env PROJECT_NAME=main vue-cli-service build", "build:mobile": "cross-env PROJECT_NAME=mobile vue-cli-service build", "build:credit": "cross-env PROJECT_NAME=credit vue-cli-service build", "build:loan": "cross-env PROJECT_NAME=loan vue-cli-service build", "build:sign": "cross-env PROJECT_NAME=sign vue-cli-service build", "build:track": "cross-env PROJECT_NAME=track vue-cli-service build", "build:approval": "cross-env PROJECT_NAME=approval vue-cli-service build", "lint": "vue-cli-service lint" },
好了,运行不同的命令试试吧。我反反复复有些莫名的报错,重装cross-env也反复好几次,全局的,局部都试过。再比如 dev 不行,dev:main就可以,我就删除了node-modules,重新下载了依赖,就可以了。 呼~~~~ 终于搞定了,希望大家能少走一些坑,拜拜~~~
