api-mock-plugin

This is a api mock plugin for webpack-dev-server, it will use application's node servers to mock api. you can use json files or mockjs to generate mock data

这是一个用于webpack-dev-server的接口mock插件，插件利用devServer的before参数来共享页面应用的服务器。你可以用json文件和mockjs包来生成mock数据

Installation

npm

$ npm install @wxhccc/api-mock-plugin -D

Usage

config in webpack

/*
* pure plugin without 'path-to-regexp'
* 不包含'path-to-regexp'模块的简洁包，需要自己安装
*/
const apiMock = require('@wxhccc/api-mock-plugin')
/* or
 * complete plugin within 'path-to-regexp'
 * 包含'path-to-regexp'模块的完整包
 */
// const apiMock = require('@wxhccc/api-mock-plugin/index.complete')

/*
 * in vue.config.js(vue-cli3) 
 */
module.exports = {
  devServer: {
    before: apiMock(path.join(__dirname, 'apiMock/'))
  }
}

API

apiMock(mockDir, options)

parameters:

• mockDir {String} The base dir of mock files, required. 存放mock数据的目录，必需参数，确实时会报错

• options {Object} The options.

• options.index {String} the entry file in mockDir, default 'index.js'. see index-content

  入口文件，默认为mockDir目录下的index.js。文件具体内容格式见index-content

• options.routes {String/String Array} the base route(s) of api request, default '/api-mock'. see express

  基础路由字符串或路由字符串数组，参阅express

• options.minDelay {Number} the min delay millisecond before response, default 0 接口响应前的最低延时，默认为0

• options.maxDelay {Number} the max delay millisecond before response, default 1000.

  接口响应前的最高延时，默认为1000，设置为0时无主动延时

  the actual delay will between minDelay an maxDelay

  实际延迟时间介于minDelay和maxDelay之间

• options.suffix {String} the suffix of api files, default 'json'

  接口文件的后缀，默认为'json'

• options.readFiles {Array} the url-filePath config. see readFiles

  请求路径和静态文件的映射数组

• options.appHanlder {Function(app)} the custom handler for app.

  自定义的app处理逻辑

  app is express application

returns: function (给devServer的before的处理函数)

readFiles

readFiles is an array of get request and static mock file. for example:

readFiles: ['/config.js', ['/apiconfig.js', 'api/config.js']]

/*
`[domain]/config.js` will read mockDir + '/config.js' file an return.

`[domain]/apiconfig.js` will read mockDir + '/api/config.js' file an return
*/

index-content

The entry file(default index.js) should export an object or a function through 'cjs' format, recommend object.

入口文件需要导出一个对象或函数，推荐导出对象形式，函数形式需要你自己处理request请求

Example:

'use strict'
/* object
 * object keys will use `path-to-regexp` to match request path(not originUrl, path not include base path)
 * 对象的键值字符串会用`path-to-regexp`去匹配请求地址的path部分（path不包含基础路径，比如不包含'/api-mock',具体见express文档）
 */
module.exports = {
  /* value is plain object */
  /* 值可以是简单json对象 */
  '/aaa': { a: 1 },
  /* value is function */
  /* 值可以是一个函数，参数是请求对象和路径参数对象 */
  '/bbb/:id': (req, params) => {
    /* req.body has parsed by `body-parser`, so you can get json/urlencode params
     * params is `{ id: 1 }` is request url is '/api-mock/bbb/1'
     */
    /* req.body 已经经过`body-parser`解析, 可以获取到通过json格式或urlencode格式发送的数据 */
    return params
  },
  /* value is special object contains $[method] keys. request will auto match method。used for restful apis */
  /* 值也可以是一个包含$[method]这种特殊key的对象。对象的键名会自动匹配请求方式。对应请求方式的值可以是对象和函数。这种方式适合restful风格的接口 */
  '/ccc/:id': {
    '$GET': (req, params) => (params),
    '$POST': { result: true }
  }
}

// or function
module.exports = function (method, path, req) {
  const { path, method } = req
  if (path === 'xxx') {
    return { data: 1 }
  }
}
