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 🙏

Samoyed

为 koa-router 提供装饰器。方便koa用户使用注解的方式定义路由

npm version NPM downloads

适用人群

  • Koa 用户
  • Typescript用户
  • 使用之前请先阅读注意事项

安装

npm install --save isamoyed

使用

非前缀模式(后期考虑干掉)

import Koa from 'koa';

import { scan } from '../build/cmjs';
import path from 'path';
const app = new Koa();
// 初始化
const ControllerDir = path.resolve(__dirname, './controller');

await scan(app,controllerDir);

前缀模式

import Koa from 'koa';

import Samoyed from '../src';
import path from 'path';
const app = new Koa();
// 初始化
const ControllerDir = path.resolve(__dirname, './controller');
const sam = new Samoyed(app, ControllerDir, '/api');

sam.scan().then(() => {
  app.listen(3000);
});

装饰器使用示例

import { Controller, Ctx, Get, Ip, Post, Req } from '../../build';
import { Context, Request } from 'koa';

@Controller('/goods')
export default class GoodsController {
  @Post('/add')
  addAction(@Ctx() ctx: Context, @Ip() ip: string) {
    return { code: 0, success: true };
  }
  @Get('/list')
  listAction(@Req() req: Request) {
    return { success: false };
  }
}

API

  • scan(app,ControllerDir):全局扫描控制器进行路由注册
    • app: Koa 实例
    • ControllerDir: 控制器文件所在目录,目前只支持单层目录
  • Controller(path:string): 定义控制器的基础路由路径
  • 支持 GET POST PUT DELETE 方法,可使用装饰器 @GET @POST @PUT @DELETE
  • 支持通过注解Ctx Request Req Response Res Query Body Param Headers Session File Files Ip 获取对应的属性

注意事项

  • controllerDir 目前只支持单层目录,暂时不支持目录嵌套。
  • 示例中的Action 方法目前只支持返回json结构,暂时不支持重定向等操作。
