Express+Mockjs+nodemon 搭建 mock 服务

安装依赖

npm i express mockjs nodemon body-parser --save-dev

• Express：Node.js Web 应用程序框架
• Mock.js：模拟数据生成
• nodemon：监听变化，实现热更新
• body-parser：请求体解析

编写 server.js

const express = require('express')
const bodyParser = require('body-parser')

const app = express()

// 解析 application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))

// 解析 application/json
app.use(bodyParser.json())

app.all('*', function (req, res, next) {
  // 允许跨域
  res.header('Access-Control-Allow-Origin', '*')
  res.header('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS')
  next()
})

app.post('/test', (req, res) => {
  res.json({ hello: 'world' })
})

app.listen('3000', () => console.log('Server on 3000'))

编写 nodemon.js

const nodemon = require('nodemon')
const path = require('path')

const resolve = (file) => path.resolve(__dirname, file)

/**
 * script 重启的脚本
 * ext 检测的文件类型
 * watch 监听哪些文件
 * ignore 忽略哪些文件
 */
const server = resolve('server.js')
nodemon({
  script: server,
  ignore: [],
  watch: [
    resolve('modules/'),
    server
  ],
  ext: 'js json'
})

nodemon.on('start', function () {
  console.log('mockServer has started')
}).on('quit', function () {
  console.log('mockServer has quit')
  process.exit()
}).on('restart', function (files) {
  console.log('mockServer restarted due to: ', files)
})

添加启动命令

"scripts": {
  "mock-server": "node nodemon.js"
}

启动后访问http://localhost:3000/test测试。
