json-server-router

简约但强大的 mock server 构建命令行工具

开始

install json-server-router

$ npm install json-server-router -g

目前 mock 文件支持 .json .jsonc .js 三种格式。 假设有文件books.json内容如下:

// books.json
{
  "update": { "code": 200, "message": "succeed", "data": true },
  "retrieve": { "code": 200, "message": "succeed", "data": true },
  "create": { "code": 200, "message": "succeed", "data": true },
  "delete": { "code": 200, "message": "succeed", "data": true }
}

运行命令$ jsr books.json

将以books.json为数据源启动 mock server, 对应生成四个接口 /books/update /books/retrieve /books/create /books/delete,其中文件中每个键值成为一个接口。

运行$ curl http://localhost:3000/books/update

返回

{
  "code": 200,
  "message": "succeed",
  "data": true
}

命令参数

jsr <root> [options]

Examples:
jsr .
jsr mock
jsr books.json
jsr books.jsonc
jsr index.js


位置:
  root  Paths to mock files dir or file 支持 .json .jsonc .js 三种格式文件           [字符串]

选项:
  --config           Path to config file [string] [default:
                     jsr.config.js]
  --port, -p         Set port         [数字] [默认值: 3000]
  --host                 [字符串] [默认值: 本机IP]
  --watch, -w        Watch file(s)    [布尔] [默认值: true]
  --open, -o         open            [布尔] [默认值: false]
  --help, -h         显示帮助信息                    [布尔]
  --version, -v      显示版本号                      [布尔]

参数说明

  • config 设置配置文件默认配置文件的地址是当前目录的下的jsr.config.js
  • watch 监控文件变化自动重新加载

jsr.config.js simple

module.exports = {
  root: 'mock',
  port: 3000
}

路由规则

如果想构建复杂的路由结构该怎么办?json-server-router 提供一个便捷的方式创建复杂路由,你只需按照一定的规则构建出对应的目录结构就好。

假设我们的目标接口为 /aaa/bbb/ccc/update,那么我们只需构造出如下的目录结构

tips 当遇到名称为 index 的文件路径拼接的时候会忽略index,当遇见键值为 index路径拼接同样也会忽略index

  • name --> prefix/name // prefix 文件目录结构 name 对象key
- aaa
  - bbb
    + ccc.json   // 在ccc.json中添加 update
or

- aaa
  - bbb
    - ccc
      +index.json // 在index.json中添加update

运行$ jsr aaa就会得到目标接口;

路由生成规则示意

-mock
 + index.json    ------>   /xxx
 + book.json     ------>   /book/xxx
 - foo
   + index.json  ------>  /foo/xxx
   + bar.json    ------>  /foo/bar/xxx
  • 文件名为index.{js,json,jsonc} 生成路由时忽略 index
  • /xxx/aaa/index 路径指向 /xxx/aaa

路由生成工具命令

为了解决复杂路由需要构建复杂目录结构的问题,现提供$ jsr route <path> 工具命令以便按照路由规则生成对应目录结构.

$ jsr route /aaa/bbb/ccc/update
$ jsr ro /aaa/bbb/ccc/update # 简写

运行上述命令将自动生成目录结构mock/aaa/bbb/ccc.json

并且ccc.json自动生成如下内容

{
  "update": {
    "code": 0,
    "data": {},
    "msg": "msg"
  }
}

自定义路由

  • /aaa/bbb/name --> prefix/aaa/bbb/name // prefix 文件目录结构

当对象 key 以/ 即认为启动自定义路由,以解决创建多层目录的弊端,假设 index.json 内容如下那么将生成路由/update/more/book

// index.json
{
  "/update/more/book": {
    "code": 200,
    "message": "自定义路由",
    "data": true
  },
  "retrieve": { "code": 200, "message": "succeed", "data": true }
 
}

rewrite

在 jsr.config.js 中添加 routes 字段,注意每个 route 必须以 / 开头

// jsr.config.js
module.exports = {
  /**
   * /api/posts # → /posts
   * /api/posts/1  # → /posts/1
   * /posts/1/show # → /posts/1
   * /posts/javascript # → /posts?category=javascript
   * /articles?id=1 # → /posts/1
   */
  routes: {
    '/api/*': '/$1',
    '/:resource/:id/show': '/:resource/:id',
    '/posts/:category': '/posts?category=:category',
    '/articles\\?id=:id': '/posts/:id'
  }
}

功能介绍

json-server-router是对json-server的扩展所以要想更好的理解下面的内容最好要先了解json-server

Filter

Use . to access deep properties

GET /posts?title=json-server&author=typicode
GET /posts?id=1&id=2
GET /comments?author.name=typicode

Paginate

Use _page and optionally _limit to paginate returned data.

In the Link header you'll get first, prev, next and last links.

GET /posts?_page=7
GET /posts?_page=7&_limit=20

10 items are returned by default

Sort

Add _sort and _order (ascending order by default)

GET /posts?_sort=views&_order=asc
GET /posts/1/comments?_sort=votes&_order=asc

For multiple fields, use the following format:

GET /posts?_sort=user,views&_order=desc,asc

Slice

Add _start and _end or _limit (an X-Total-Count header is included in the response)

GET /posts?_start=20&_end=30
GET /posts/1/comments?_start=20&_end=30
GET /posts/1/comments?_start=20&_limit=10

Works exactly as Array.slice (i.e. _start is inclusive and _end exclusive)

Operators

Add _gte or _lte for getting a range

GET /posts?views_gte=10&views_lte=20

Add _ne to exclude a value

GET /posts?id_ne=1

Add _like to filter (RegExp supported)

GET /posts?title_like=server

Add q

GET /posts?q=internet

Relationships

To include children resources, add _embed

GET /posts?_embed=comments
GET /posts/1?_embed=comments

To include parent resource, add _expand

GET /comments?_expand=post
GET /comments/1?_expand=post

To get or create nested resources (by default one level, add custom routes for more)

GET  /posts/1/comments
POST /posts/1/comments

当使用json-server 我们可以通过构建路由/get/users?_page=7&_limit=10进行分页查询但是query的关键词必须是指定的, 在json-server-router中可以再jsr.config.js中自定义queryMap字段来修改关键词的名字,配置好了之后就可以通过/get/users?page=7&len=10进行分页查询

//jsr.config.js
{
  queryMap: [
    ['_page', 'page'],
    ['_limit', 'len']
  ]
}

POST PUT DELETE 目前全部跟 GET 一致

关于非GET请求你不需要定义mock filesjson-server-router对所有非GET请求进行统一处理不管其路由是什么一致通过 handler 函数处理

文件上传

jsr 支持文件上传功能只要添加 file 魔法注释即可"upload[file]",目前上传文件对应的name固定为file

{
  "upload[file]": { "code": 200, "message": "succeed", "data": true }
}

/xxxx/upload返回结果如下:

{
  "code": 200,
  "files": [
    {
      "destination": "public/temp",
      "encoding": "7bit",
      "fieldname": "file",
      "filename": "0668151cf3f749154c6b1942abe38ad6",
      "mimetype": "application/javascript",
      "originalname": "jsr.config.js",
      "path": "public/temp/0668151cf3f749154c6b1942abe38ad6",
      "size": 494
    }
  ]
}

推一手httpie:使用 httpie 如下命令即可完成上传文件的功能:

$ http -f xxxx/upload file@somefile.xx

生成随机数据

Using JS instead of a JSON file, you can create data programmatically.

// index.js
module.exports = () => {
  const data = { users: [] }
  // Create 1000 users
  for (let i = 0; i < 1000; i++) {
    data.users.push({ id: i, name: `user${i}` })
  }
  return data
}
$ jsr index.js

Tip use modules like Faker, Casual, Chance or JSON Schema Faker.

默认集成 mockjs

为了更好的支持生成随机数据的需求现在默认集成mockjs

举例说明:可以在 mock 文件中直接使用 mockjs 语法如下文例子所示

// mockjs 例子
module.exports = {
  // 属性 list 的值是一个数组,其中含有 1 到 10 个元素
  'list|10': [
    {
      // 属性 id 是一个自增数,起始值为 1,每次增 1
      'id|+1': 1,
      // 随机中文名
      name: '@cname',
      // 随机地址
      address: '@city(true)',
      web: '@url',
      guid: '@guid',
      // 生成 200x 200 的图片
      image: "@image('200x200')",
      constellation: '@constellation',
      // 三选一
      'oneOf|1': ['one', 'two', 'three'],
      // 生成满足正则条件的字符串
      regexp1: /[a-z][A-Z][0-9]/,
      regexp2: /\w\W\s\S\d\D/,
      regexp3: /\d{5,10}/
    }
  ]
}

战斗人员可以作为json-server中间件引用

可以参考cli/server.js

const jsonServer = require('json-server')
const server = jsonServer.create()
const middlewares = jsonServer.defaults() // { static: 'public' }
const JsonServerRouter = require('json-server-router')

/**
 * @prop {string} root mock文件根目录默认为 'mock'
 * @prop {number} port 端口号跟json-server 一致 默认为 3000
 * @prop {string} publicPath 生成默认首页的地址,跟json-server 配置一致 默认'public',如果修改路径的话那么json-server 对应的配置也要改
 * @prop {bool} open 是否用浏览器打开 默认 true
 */

const router = new JsonServerRouter({
  root: 'mock',
  port: 3000,
  publicPath: 'public'
})

server.use(middlewares)

server.use(router.routes())
server.use(router.rewrite())

server.listen(3000, () => {
  console.log('JSON Server is running')
})
