项目

创建

vue create single         # vue 2.6.14

配置

// vue.config.js
const { defineConfig } = require("@vue/cli-service");
module.exports = defineConfig({transpileDependencies: true,lintOnSave: false,      // 暂时关闭 eslintassetsDir: 'static',    // 静态资源打包存储文件夹devServer: {port: 3030, //端口号open: true, //自动打开浏览器}
});

环境区分

• vue.config.js 同级创建文件
• .env.test

NODE_ENV = "test"
VUE_APP_TITLE = "测试"
VUE_APP_URL = "test"

• .env.production

NODE_ENV = "production"
VUE_APP_TITLE = "生产"
VUE_APP_URL = "production"

• index.html

<title> <%= process.env.VUE_APP_TITLE %></title>

• package.json

{"private": false,"scripts": {"serve": "vue-cli-service serve --mode test","serve1": "vue-cli-service serve --mode production","build": "vue-cli-service build --mode test","build1": "vue-cli-service build --mode production","lint": "vue-cli-service lint"}
}

UI

cnpm install element-ui@2.15.14

• main.js

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';Vue.use(ElementUI);

Sass / Scss

cnpm install node-sass@6.0.0 --save-dev
cnpm install sass-loader@11.1.0 --save-dev
cnpm install style-loader@3.3.4 --save-dev

}
</style>

axios

• src/http/index.js

import axios from "axios";let service = axios.create({// baseURL: "https://cnodejs.org/api/v1", //相同绝对路径baseURL: process.env.VUE_APP_URL, //相同绝对路径timeout: 100000, //超过这么多时间，则请求终止headers: {//请求头携带数据的格式"Content-Type": "application/json;charset=UTF-8",// "Content-Type": "application/x-www-form-urlencoded;charset=utf-8",},
});
// 添加请求拦截器（Interceptors）
service.interceptors.request.use(function (config) {// 发送请求之前做写什么let token = localStorage.getItem("token");// 如果有if (token) {// 放在请求头（token跟后端沟通，他需要什么该成什么就可以了）config.headers.authorization = token;}return config;},function (error) {// 请求错误的时候做些什么return Promise.reject(error);}
);
// 添加响应拦截器
service.interceptors.response.use(function (response) {// 对响应数据做点什么return response.data;},function (error) {// 对响应错误做点什么return Promise.reject(error);}
);export default service;

• src/http/api.js

import request from "./index";export async function Ceshi(params) {return request({url: "/topics",method: "GET",params,});}export async function Ceshi2(data) {return request({url: "/Storage/GetStorageLack",method: "POST",data,});}

• 使用

<script>
import { Ceshi } from "@/http/api";
export default {async created() { var a = await Ceshi();console.log(a);},
};
</script>

router

cnpm i vue-router@3 

• src/router/index.js

import Vue from "vue";
import Router from "vue-router";Vue.use(Router);//配置路由
const router = new Router({// mode: "history",mode: "hash",routes: [{path: "/",name: "Cs",component: () => import("@/view/c.vue"),},],
});//导出
export default router;

• main.js

import router from './router'new Vue({render: h => h(App),router
}).$mount('#app')

• App.vue

<router-view></router-view>

vuex

cnpm install vuex@3

• src/store/modules/c1.js

export default {namespaced: true,state: {c1: [{id: "01001",name: "如何",},{id: "01002",name: "如何学好编程",},],},mutations: {},actions: {},
};

• src/store/index.js

import Vue from "vue";
import Vuex from "vuex";
import c1 from "./modules/c1";Vue.use(Vuex);export default new Vuex.Store({modules: {c1: c1,},state: {id: "01",},mutations: {},
});

• main.js

import store from './store'
new Vue({render: h => h(App),store
}).$mount('#app')

Vue2 多模块打包

• .env.test

MODEL_NAME = "test"

• .env.production

MODEL_NAME = "test1"

• vue.config.js

let modelName = process.env.MODEL_NAME || "";
let outputDir = modelName ? `dist/${modelName}/` : "dist/";
const config = {test: {pages: {index: {filename: "index.html",entry: "src/main.js",template: "public/index.html"}},devServer: {port: 3032, //端口号open: true, //自动打开浏览器}},test1: {pages: {index: {filename: "index.html",entry: "src/main.js",template: "public/index.html"}},devServer: {port: 3030, //端口号open: true, //自动打开浏览器}},
};const { defineConfig } = require("@vue/cli-service");
module.exports = defineConfig({transpileDependencies: true,lintOnSave: false, //暂时关闭 eslint...config[modelName],outputDir: outputDir,       // 项目输出目录assetsDir: 'static'
});
