How to use mock to simulate data problems in vite+vue3

1. Install mockjs and vite-plugin-mock

npm i mockjs vite-plugin-mock --save-dev

2. Configure

vite-plugin-mock usage in the vite.config.ts file

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { viteMockServe } from 'vite-plugin-mock'
 
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue(),
    viteMockServe({
      supportTs:false,
      logger: false,
      mockPath: "./mock/"
    })
  ]
})

## The meaning of the configuration content in #vite-plugin-mock

{
supportTs?: boolean; --是否读取ts文件模块，设置为true时不能读取js文件

logger?:boolean; --是否在控制台显示请求日志
mockPath?: string;  --设置模拟数据的存储文件夹，如果不是index.js需要写明完整路径
ignore?: RegExp | ((fileName: string) => boolean);--读取文件时忽略指定格式的文件
watchFiles?: boolean;--是否监视mockPath文件夹内文件的修改
localEnabled?: boolean;--设置是否启用本地 xxx.ts 文件，不要在生产环境中打开它.设置为 false 将禁用 mock 功能
ignoreFiles?: string[]; --读取文件时忽略的文件
configPath?: string;--设置模拟读取的数据条目。 当文件存在并且位于项目根目录中时，将首先读取并使用该文件。 配置文件返回一个数组
prodEnabled?: boolean;--设置打包是否启用 mock 功能
injectFile?: string;--如果生产环境开启了 mock 功能,即prodEnabled=true.则该代码会被注入到injectFile对应的文件的底部。默认为main.{ts,js}。这样做的好处是,可以动态控制生产环境是否开启 mock 且在没有开启的时候 mock.js 不会被打包。如果代码直接写在main.ts内，则不管有没有开启,最终的打包都会包含mock.js

injectCode?: string;--injectCode代码注入的文件,默认为项目根目录下src/main.{ts,js}

}

3. Create a mock folder in the root directory

New folder mock/index.js

export default [{
    type:'get',
    url:'/user/login',
    response: () => {
        return {isAuth:true}
    }
},{
    type:'get',
    url:'/user/menu',
    response: () => {
        return {menusList:[{
            id:'/sysManagent',
            title:'系统管理',
            subMenuList:[
                {
                    id:'/userList',
                    title:'用户管理',
                    path:'/user/manage'
                },
                {
                    id:'/roleList',
                    title:'角色管理',
                    path:'/user/role'
                },
                {
                    id:'/permissionList',
                    title:'权限管理',
                    path:'/user/permission'
                }
            ]
        },{
            id:'businessManagent',
            title:'业务管理',
            subMenuList:[
                {
                    id:'/businessList',
                    title:'业务逻辑'
                }
            ]
        }],statusCode:200}
    }
}]

in the file. 5. Others

If the mock folder is built in the src file directory, you need to modify the tsconfig.json file

"include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue","src/mock/**/*.ts"],
