Getting Started

📦 Install rd-mock

yarn add rd-mock --dev # or：npm install rd-mock --dev

🔨 Usage example

• create schema && start server

const { rdMock } = require('rd-mock')

// use `mockjs` schema to create mock data
// field 'id' is required in any schema
const schema = {
  'a|5': [
    {
      'id|+1': 1,
      'money|1-400': 1,
      name: '@cname',
      address: `@city(true)`,
      email: `@email`,
    },
  ],
}

// start mock server
rdMock(schema, {
  port: 3000,
  delay: 0,
  responseInterceptors: [
    async (ctx, next) => {
      if (ctx.request.method === 'GET' && ctx.request.url === 'a') {
        const { data } = ctx.body
        // custom response result
        ctx.body.data = {
          count: 400,
          list: data,
        }
      }
      await next()
    },
  ],
  requestInterceptors: [
    async (ctx, next) => {
      // custom request params
      const query = ctx.query
      if (query['page']) {
        query['_page'] = query['page']
        delete query['page']
      }
      if (query['pageSize']) {
        query['_limit'] = query['pageSize']
        delete query['pageSize']
      }
      await next()
    },
  ],
})

• use simple router

const url = 'http://localhost:3000/a'
const headers = {
  'Content-Type': 'application/json;charset=utf-8',
}
fetch(`${url}`, {
  //get data
  method: 'GET',
})
  .then((res) => res.json())
  .then((response) => {
    console.log('all data', response)
    return fetch(`${url}`, {
      //create data
      method: 'POST',
      body: JSON.stringify({ id: 6, name: 'create data' }),
      headers,
    })
  })
  .then(() => {
    return fetch(`${url}`, {
      // update data
      method: 'PUT',
      body: JSON.stringify({ id: 5, name: 'update date' }),
      headers,
    })
  })
  .then(() => {
    return fetch(`${url}`, {
      // delete data
      method: 'DELETE',
      body: JSON.stringify({ id: 1 }),
      headers,
    })
  })

• check the db.json

{
  "a": [
    {
      "id": 2,
      "money": 316,
      "name": "阎敏",
      "address": "辽宁省 丹东市",
      "email": "[e-mail]"
    },
    {
      "id": 3,
      "money": 391,
      "name": "史军",
      "address": "青海省 海东市",
      "email": "[e-mail]"
    },
    {
      "id": 4,
      "money": 326,
      "name": "邱敏",
      "address": "上海 上海市",
      "email": "[e-mail]"
    },
    {
      "id": 5,
      "money": 81,
      "name": "update date",
      "address": "西藏自治区 山南地区",
      "email": "[e-mail]"
    },
    {
      "id": 6,
      "name": "create data"
    }
  ]
}

Schema

Router Rule

Singular routes

GET    /profile # get data
POST   /profile # create data
PUT    /profile # update data by id
DELETE  /profile # remove data by id

Filter

• use '_num' to parse string '20'

GET /posts?name=xxx&id=1
GET /posts?number_num=20

Paginate

• Use _page and _limit to paginate data.

GET /posts?_page=2

GET /posts?_page=3&_limit=5

• default _page = 1 , default _limit =10

Sort

• Add _sort and _order

GET /posts?_sort=id&_order=asc
GET /posts?_order=desc

• default _sort = id ; default _order=asc

Slice

• Add _start and _end

GET /posts?_start=20&_end=30

• default _start = -1 ; default _end =-1
• Works exactly as Array.slice

Operators

• Add _gte or _lte for getting a range

GET /posts?views_gte=10
GET /posts?views_gte=5&view_lte=20&id_lte=10

• Add _ne to exclude a value

GET /posts?id_ne=1

• Add _like to filter

GET /posts?title_like=xxx

• Works exactly as String.includes

Warning

• Same field Only one operator will be matched

// wrong
 get('/user?id_ne=1&id_ne=2&id_ne=3'))
// only  id_ne =3   will work

// right
get('/user?id_ne=8&id_gte=5')

• the _limit=10 is default when you used operator pipe

// schema
'user|20': [
    {
      'id|+1': 1,
    },
  ],

// test
 expect((await axios.get('/user?id_gte=0')).data.data.length).toBe(10)


// but you can set the _limit to change the defalut _limit

// test
 expect((await axios.get('/user?id_gte=0&_limit=20')).data.data.length).toBe(20)

Result

• only GET request will fetch the Data, and the rest of the requests have only a status code and status msg

export const SUCCESS = {
  rtn: 0,
  msg: '成功',
  data: null,
}

/* 参数错误：10001-19999 */
export const PARAM_IS_INVALID = {
  rtn: 10001,
  msg: '参数无效',
  data: 'any',
}
export const PARAM_IS_BLANK = {
  code: 10002,
  msg: '参数为空',
  data: 'any',
}

/* 系统错误：40001-49999 */
export const SYSTEM_INNER_ERROR = {
  rtn: 40001,
  msg: '系统繁忙，请稍后重试',
  data: 'any',
}
/* 数据错误：50001-599999 */
export const RESULE_DATA_NONE = {
  rtn: 50001,
  msg: '数据未找到',
  data: 'any',
}
export const DATA_IS_WRONG = {
  rtn: 50002,
  msg: '数据有误',
  data: 'any',
}
export const DATA_ALREADY_EXISTED = {
  rtn: 50003,
  msg: '数据已存在',
  data: 'any',
}
/* 接口错误：60001-69999 */
export const INTERFACE_ADDRESS_INVALID = {
  rtn: 60004,
  msg: '接口地址无效',
  data: 'any',
}

Router Pipe
