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 🙏

更改

  1. 解决在使用以后 route 挂载不上的问题(原因:没有引用controller文件注解不会触发
  2. Controller 添加prefix
  3. 添加参数校验方法paramsRequired

安装

# yarn
yarn add koa-router-decorators-plus

# npm
npm i koa-router-decorators-plus

使用方法

Controller 的使用

import { Controller, get, paramsRequired } from 'koa-router-decorators-plus'
import * as Koa from 'koa'
@Controller('/test')
export default class startApi {
  // 括号中如果不传入参数  则自动拼接url 即:/test/getIndex
  @get()
  async getIndex(ctx: Koa.Context, next: Function) {
    ctx.body = {
      a: 66666,
    }
  }

  @paramsRequired(['username', 'password'])
  @get('/login')
  async getString(ctx: Koa.Context, next: Function) {
    // 使用paramsRequired后会自动扫描ctx.request.query或则ctx.request.body上是否存在相关参数
    // 没有则返回400, 有则进入当前handler
    const { username, password } = ctx.request.query
    ctx.body = {
      username,
      password,
    }
  }

  @paramsRequired({
    body: ['username', 'password'],
    query: ['id'],
  })
  @post('/update')
  async update(ctx: Koa.Context, next: Function) {
    // 按配置读取body以及query上的参数
    const { username, password } = ctx.request.body
    ctx.body = {
      username,
      password,
    }
  }
}

路由注册

import Koa from 'koa'
import loadController from 'koa-router-decorators-plus'
import KoaRouter from 'koa-router'
const app = new Koa()
// 第二个参数为存放contorller的文件夹
loadController(router, resolve(__dirname, './controllers'))
const router = new KoaRouter()
app.use(router.routes())
app.use(router.allowedMethods())
