✅ Generate multi page configuration

build/newUtils.js The getEntry method in generates the page path and the corresponding html object according to all html files in the directory.
var pages = utils.getEntry(['./src/module/**/*.html']);

The returned result is:

The returned result is:

{ 'aa/as/dd/fd/ddd':{ entry: './src/module/aa/as/dd/fd/ddd/ddd.js', template: './src/module/aa/as/dd/fd/ddd/ddd.html' }, 'aa/ddd':{ entry: './src/module/aa/ddd/ddd.js', template: './src/module/aa/ddd/ddd.html' }, ss:{ entry: './src/module/ss/ss.js', template: './src/module/ss/ss.html' } } Copy code

✅ Configure multiple environment variables

package.json The scripts in is configured with dev qa prd to execute different environments through -- mode xxx

• Start local through npm run dev and execute development
• Through npm run qa packaging test, perform the staging
• Package formally and execute production through npm run prd

VUE_APP_ The variable at the beginning of the code can be process.env.VUE_APP_ Visit. For example, VUE_APP_ENV = 'development' passed process.env.VUE_APP_ENV access. Except VUE_APP_ *In addition to variables, there are two special variables, node, that are always available in your application code_ Env and BASE_URL

Create a new. env in the project root*

• . env local development environment configuration

NODE_ENV = development VUE_APP_SERVICE_URL = BASE_URL = ./ Copy code

• . env.qa Test environment configuration

NODE_ENV = production VUE_APP_SERVICE_URL = http://www.baidu.com BASE_URL = /shopsystem/static/weixin/dist/ Copy code

• . env.prd Formal environment configuration

NODE_ENV = production VUE_APP_SERVICE_URL = http://www.baidu.com BASE_URL = /shopsystem/static/weixin/dist/ Copy code

Configure the variables of the corresponding environment. Take the local environment file. env for example. Users can modify it according to their needs

// Local environment configuration NODE_ENV = development VUE_APP_SERVICE_URL = VUE_APP_TEST=test BASE_URL = ./ Copy code

Depending on the environment, the variables will be different

// Introduce different baseApi addresses according to different environments const instance = axios.create(); var path = process.env.VUE_APP_SERVICE_URL; instance.defaults.baseURL = path; Copy code

✅ rem adaptation scheme

Don't worry. The project has been configured with rem adaptation. The following is just an introduction:

The style in Vant uses px as the unit by default. If you need to use rem units, the following two tools are recommended:

• postcss-pxtorem Is a postcss plug-in for converting units to rem
• lib-flexible Used to set the rem reference value

A basic configuration of postcss is provided below, which can be modified based on the project requirements

// https://github.com/michael-ciniawsky/postcss-load-config module.exports = { plugins: { postcss: { plugins: [ require('postcss-pxtorem')({ rootValue: 37.5, // Base of conversion selectorBlackList: [], // Ignore transform regular matches propList: ['*'], }), ] } } } Copy code

When your child component uses scoped, but you want to modify the style of the child component in the parent component, you can use > > >

✅ Vuex status management

directory structure

main.js Introduction

import Vue from 'vue' import App from './App.vue' import store from './store' new Vue({ el: '#app', router, store, render: h => h(App) }) Copy code

use

<script> import from 'vuex' export default { computed: { ...mapGetters(['userName']) }, methods: { // Action passed store.dispatch Method trigger doDispatch() { this.$store.dispatch('setUserName', 'Oh, good. Let's hurry and pay attention to the official account. The organization is waiting for you.~') } } } </script> Copy code

✅ Vue-router

In this case, the hash mode is adopted, and the developer modifies the mode base according to the requirements

Note: if you use the history mode, vue.config.js The publicPath in should be modified accordingly

import Vue from 'vue' import Router from 'vue-router' Vue.use(Router) export const router = [ { path: '/', name: 'index', component: () => import('@/views/home/index'), // Route lazy load meta: { title: 'home page', // Page title keepAlive: false // Keep alive ID } } ] const createRouter = () => new Router({ // mode: 'history', / / if you are in history mode, you need to configure vue.config.js publicPath // base: '/app/', scrollBehavior: () => ({y: 0}), routes: router }) export default createRouter() Copy code

✅ Configure alias

const path = require('path') const resolve = dir => path.join(__dirname, dir) const IS_PROD = ['production', 'prod'].includes(process.env.NODE_ENV) module.exports = { chainWebpack: config => { // add alias config.resolve.alias .set('@', resolve('src')) .set('assets', resolve('src/assets')) } } Copy code

✅ Configure proxy cross domain

If your project needs cross domain settings, you need to call vue.config.js proxy comment and configure the corresponding parameters

module.exports = { devServer: { // .... proxy: { //Configure cross domain '/api': { target: 'https://test.xxx.com', // Domain name of the interface // ws: true, / / enable websockets changOrigin: true, // Start the agent and create a virtual server locally pathRewrite: { '^/api': '/' } } } } } Copy code

✅ Configure packaging analysis

const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin module.exports = { chainWebpack: config => { // Packaged Analytics if (IS_PROD) { config.plugin('webpack-report').use(BundleAnalyzerPlugin, [ { analyzerMode: 'static' }
