kakao v0.4.1

Kakao

An API-driven framework for building nodejs apps, using MVC conventions. It only will provide a structure, inspired on Ruby on Rails, that will allow you to organise better your projects, initialise your own or third party libraries, call in a easy way your models, helpers, etc.

Features

• MVC architecture project
• ES6 support
• Helpers support
• ORM, ODM or DB driver independent
• Well organized configuration files and routes

TODO

• Log
  • accessLog
  • requestLog
• Router
• REST
  • GET
  • POST
  • PUT
  • DELETE
• ORM
  • withRelated返回指定的columns - mask plugin
  • 自定义sql
  • schema/joi
  • 分页
  • 使用bookshelf-cascade-delete删除关联表数据，避免使用数据库外键
  • 根据models自动创建CRUD路由
  • insert/update时更新关联表数据
  • joi.description()不起作用
• Debug
• HTTPS support
• Cache
• Task
• Test
• Deploy
• Daemon
• Others
  • xx

Installation

First install node.js and mysql. Then:

1. Clone the project to local

$ git clone https://github.com/zhongzhi107/kakao

1. Install dependencies

$ yarn

1. Modify config file config/index.js

$ vi config/index.js

connection: {
  host: process.env.MYSQL_HOST || 'localhost',
  user: process.env.MYSQL_USER || 'root',
  password: process.env.MYSQL_PASSWORD || '',
  database: process.env.MYSQL_DATABASE || 'kakao',
  port: 3306,
  charset: 'utf8',
  timezone: 'UTC',
  // debug: true,
}

1. Migrate data

$ yarn run migrate:latest

1. Start the application

$ yarn start

By default the app tries to connect to port 3000. After starting the application you can check it at http://localhost:3000/roles

Convention

以下是默认约定，如果不想按着默认约定编码，可以在代码中使用指定参数的方式更改

• 数据库、表应该像变量名一样，全部采用小写，但单词之间以下划线分隔，而且表名始终是复数形式的
• 文件名应该全部小写，单词之间用下划线
• 关联表名称默认为用下划线连接的被关联的两个表名，且按2个表名称的字母排序先后顺序连接
  • users和posts的关联表名称应该为posts_users
  • tags和posts的关联表名称应该为posts_tags
  • users和tags的关联表名称应该为tags_users
• 关联表名中关联的字段默认为 被关联表名称的单数_id，如 user_id tag_id post_id
• ...

路由

kakao能根据model自动创建RESTful路由地址

创建一个最简单的CRUD路由

import Role from '../models/roles';
import ResourceRouter from '../utils/router';

export default ResourceRouter.define(Role.collection())

上面的代码会自动创建以下路由：

创建一个嵌套路由

import Role from '../models/role';
import ResourceRouter from '../utils/router';

const users = ResourceRouter.define({
  // 假设在role model中已经设定了role和user的关联关系
  collection: (ctx) => ctx.state.role.users(),
  name: 'users',
  setup(router) {
    router
      .use(async (ctx, next) => {
        ctx.state.role = await Role.findById(
          ctx.params.role_id,
          {require: true}
        );
        await next();
      })
      .crud();
  },
});

export default ResourceRouter.define({
  collection: Role.collection(),
  setup(router) {
    router.crud();
    // router.create().read().update().destroy();

    // 使用嵌套路由
    router.use('/roles/:role_id(\\d+)', users.routes());
  },
});

上面的代码会自动创建以下路由：

API支持的querystring

• 查询类
  • http://localhost/roles?where=id&where=>&where=10
  • http://localhost/roles??where[name]=sales
• 返回值类
  • 分页
    • http://localhost/roles?page=1&page_size=15
  • 自定义返回字段
    • http://localhost/roles?mask=custom
    • http://localhost/roles?mask=id,name
  • 返回关联模型数据
    • http://localhost/roles?withRelated=users
  • 排序
    • http://localhost/roles?sort=created_at&direction=DESC

Overview

Notes

• curl传递多个querystring参数时，& 前需要加 \，如 curl http://localhost/roles?sort=id\&direction=desc
• curl传递带[]参赛时，需要加上 --globoff 参数，如 curl --globoff http://localhost/roles?where[name]=sales
