Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Build status Dependency Status devDependency Status

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

  • [x] Log
    • [x] accessLog
    • [x] requestLog
  • [x] Router
  • [x] REST
    • [x] GET
    • [x] POST

  • [ ] HTTPS support

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
    • usersposts的关联表名称应该为posts_users
    • tagsposts的关联表名称应该为posts_tags
    • userstags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:

提交方式 | 路由 | 说明 --- | --- | --- POST | /roles | 新建一个角色 GET | /roles | 列出所有角色 GET | /roles/:id | 获取某个指定角色的信息 PATCH | /roles/:id | 更新某个指定角色的信息 DELETE | /roles/:id | 删除某个角色

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:

提交方式 | 路由 | 说明 ---|---|--- POST|/roles|新建一个角色 GET|/roles|列出所有角色 GET|/roles/:id|获取某个指定角色的信息 PATCH|/roles/:id|更新某个指定角色的信息 DELETE|/roles/:id|删除某个指定角色的信息 POST|/roles/:role_id/users|新增一个某个指定角色的用户 GET|/roles/:role_id/users|列出某个指定角色的所有用户 GET|/roles/:role_id/users/:user_id|列出某个指定角色的指定用户 PATCH|/roles/:role_id/users/:user_id|修改某个指定角色的指定用户 DELETE|/roles/:role_id/users/:user_id|删除某个指定角色的指定用户

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
