How to use mockjs to randomly simulate data in Vue3+Vite project
在vite中使用mockjs进行模拟数据,需要借助新的依赖进行使用
一、安装mockjs
yarn add mockjs -S 或 npm i mockjs -D
二、安装vite-plugin-mock
npm i vite-plugin-mock -D
三、在src/mock/source文件夹下创建user.ts
在index.vue中放入以下内容:
import { MockMethod } from 'vite-plugin-mock' export default [ { url: '/api/getUserInfo', // 注意,这里只能是string格式 method: 'get', response: () => { return { menusList: [{ id: '1', title: '南辰', subMenuList: [ { id: '11', title: '南', path: '/user/nan' }, { id: '12', title: '小', path: '/user/xiao' }, { id: '13', title: '辰', path: '/user/chen' } ] }, { id: '2', title: '希', subMenuList: [ { id: '21', title: '玩游戏', path: '/user/play' } ] }] } } } ] as MockMethod[] // 这里其实就是定义数据格式的,不了解的同学可以参考typescript的官方文档
四、开发环境配置
如果只是本地开发环境时使用,直接看下面即可步骤
在vite.config.ts进行个人配置
import { viteMockServe } from 'vite-plugin-mock' export default defineConfig({ plugins: [ viteMockServe({ mockPath: "./src/mock/source", // 解析刚刚user.ts的位置 localEnabled: true // 是否开启开发环境 }) ] })
在页面中引入
<template> <div>{{name.name}}</div> <div>{{nc}}</div> </template> <script lang='ts'> import { useRoute } from "vue-router"; //引入路由组件 import { onMounted, ref } from "vue"; import axios from "axios"; export default { setup() { const nc = ref(""); onMounted(() => { axios.get("/api/getUserInfo").then((res) => { console.log(res); nc.value = res.data.menusList[0].title; console.log(nc.value); }); }); const $route = useRoute(); const name = $route.query; return { name, nc, }; }, }; </script> <style scoped> </style>
打印效果如下:
如果想使用随机数可以看接下来的步骤
如果只要随机数则直接生成即可
想要随机数在return中放入随机条件即可。
如果想要用随机数中的图片就需要从mockjs中引入一个Random方法
在页面上进行循环:
<template> <div v-for="(item,index) in list" :key="index"> <img src="/static/imghwm/default1.png" data-src="item.image" class="lazy" : alt=""> <p>{{item.id}}</p> </div> </template> <script lang='ts'> import { useRoute } from "vue-router"; //引入路由组件 import { onMounted, ref } from "vue"; import axios from "axios"; export default { setup() { const list = ref(""); onMounted(() => { axios.get("/api/getUserInfo").then((res) => { console.log(res); let lis = res.data.list; console.log(list.value =lis); }); }); return { nc, list, }; }, }; </script> <style scoped> </style>
这里的Random.image()方法是从官网上拿下来用的
效果如下:
实现随机不同的图片+字段
import { MockMethod } from 'vite-plugin-mock' export default [ { url: '/api/getUserInfo', // 注意,这里只能是string格式 method: 'get', response: () => { return { 'list|1-10': [{ // 属性 id 是一个自增数,起始值为 1,每次增 1 'id|+1': 1, /* image: Random.image() */ "title": "@ctitle", "color":'@color', "image":"@image('','@color')" }], } } } ] as MockMethod[]
index.vue
<template> <div v-for="(item,index) in list" :key="index"> <img src="/static/imghwm/default1.png" data-src="item.image" class="lazy" : alt=""> {{item.title}} </div> </template> <script lang='ts'> import { useRoute } from "vue-router"; //引入路由组件 import { onMounted, ref } from "vue"; import axios from "axios"; export default { setup() { const list = ref(""); onMounted(() => { axios.get("/api/getUserInfo").then((res) => { console.log(res); let lis = res.data.list; console.log(lis); console.log(list.value = lis); }); }); return { list, }; }, }; </script> <style scoped> </style>
效果如下:

Vue.js improves user experience through multiple functions: 1. Responsive system realizes real-time data feedback; 2. Component development improves code reusability; 3. VueRouter provides smooth navigation; 4. Dynamic data binding and transition animation enhance interaction effect; 5. Error processing mechanism ensures user feedback; 6. Performance optimization and best practices improve application performance.

Vue.js' role in web development is to act as a progressive JavaScript framework that simplifies the development process and improves efficiency. 1) It enables developers to focus on business logic through responsive data binding and component development. 2) The working principle of Vue.js relies on responsive systems and virtual DOM to optimize performance. 3) In actual projects, it is common practice to use Vuex to manage global state and optimize data responsiveness.

Vue.js is a progressive JavaScript framework released by You Yuxi in 2014 to build a user interface. Its core advantages include: 1. Responsive data binding, automatic update view of data changes; 2. Component development, the UI can be split into independent and reusable components.

Netflix uses React as its front-end framework. 1) React's componentized development model and strong ecosystem are the main reasons why Netflix chose it. 2) Through componentization, Netflix splits complex interfaces into manageable chunks such as video players, recommendation lists and user comments. 3) React's virtual DOM and component life cycle optimizes rendering efficiency and user interaction management.

Netflix's choice in front-end technology mainly focuses on three aspects: performance optimization, scalability and user experience. 1. Performance optimization: Netflix chose React as the main framework and developed tools such as SpeedCurve and Boomerang to monitor and optimize the user experience. 2. Scalability: They adopt a micro front-end architecture, splitting applications into independent modules, improving development efficiency and system scalability. 3. User experience: Netflix uses the Material-UI component library to continuously optimize the interface through A/B testing and user feedback to ensure consistency and aesthetics.

Netflix mainly considers performance, scalability, development efficiency, ecosystem, technical debt and maintenance costs in framework selection. 1. Performance and scalability: Java and SpringBoot are selected to efficiently process massive data and high concurrent requests. 2. Development efficiency and ecosystem: Use React to improve front-end development efficiency and utilize its rich ecosystem. 3. Technical debt and maintenance costs: Choose Node.js to build microservices to reduce maintenance costs and technical debt.

Netflix mainly uses React as the front-end framework, supplemented by Vue for specific functions. 1) React's componentization and virtual DOM improve the performance and development efficiency of Netflix applications. 2) Vue is used in Netflix's internal tools and small projects, and its flexibility and ease of use are key.
