fewAPI

基于 NodeJS 和 MongoDB | Base on NodeJS and MongoDB

1.目标 - Target

• Use a few code to build a api server base on mongodb databases;
• 用最少的代码，构建一个基于 mongodb 数据库的 API 服务；

• I have use the version below. And lower version you need have a try to test whether right or not.
• 我（作者）使用下面的版本进行的代码编写，更低的版本，需要你自己试一下。

• nodejs 12
• mongodb 3.4
• mongoose 5.9.6
• koa 2

2.快速开始 - Quick Start

npm install fewapi

or

yarn add fewapi

index.js

const few = require("fewapi");

// set your own config
// 设置你的配置
few.setConfig({
  // databases connection
  // 数据库连接
  mongo: "mongodb://localhost/test",
  // API response that you can custom your own resp struct, only include these three key words.
  // 接口返回格式，你可以自定义自己的结构，只能包含这三个字段
  response: {
    errno: "errno",
    errmsg: "errmsg",
    data: "data",
  },
  // entities each one are several api
  // 每个数据库实体可以包含多个 api
  entities: [
    {
      name: "user",
      api: "add,update,delete,list,detail,page",
      // fields is entirely mapping to mongoose schema
      // you can find docs here http://www.mongoosejs.net
      // 所有 fields 字段完全对应 mongoose 的 schema
      // 你可以去这里看文档 http://www.mongoosejs.net
      fields: {
        created_at: { type: Date },
        updated_at: { type: Date },
        name: { type: String, default: "", unique: true },
        gender: { type: String, default: "" },
        birthday: { type: Date, default: null },
        mate: { type: String, default: "" },
        children: [String],
      },
    }
  ]
})

// start a server serve at port 3000
// 启动 server 服务在 3000 端口
few.run(3000);

3.默认API - Default API

• You can choose generate one or more api in one model like this:
• 你可以选择生成一个或者多个 api，像下面这样：

...
entities: [
    {
      name: "user1",
      api: "add,list", // 这里不一样。difference here.
      fields: {
        name: { type: String, default: ""},
      },
    }, {
      name: "user2",
      api: "add,page,detail",
      fields: {
        name: { type: String, default: ""},
      },
    }, {
      name: "user3",
      api: "update",
      fields: {
        name: { type: String, default: ""},
      },
    }
  ]
...

• We well have api like this:
• 我们生成了下面的API：

POST /user1/add
GET  /user1/list
POST /user2/add
GET  /user2/page
GET  /user2/detail
POST /user3/update

4.API 列表 - API list

• You can find all API that fewAPI support here.
• 你能在下面找到所有 fewAPI 支持的生成 API。
