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 🙏

requestable

在普通的emitter上包装一层,以支持类似http的请求响应模式

实际工作中经常会用到单向触发的api 也就是一个收 一个发

  • tcp 的 on('data') 和 write
  • udp 的 on('data') 和 write
  • mqtt 的 subscribe 和 publish
  • iframe
    • window.parent.postMessage
    • window.addEventListener('message',onMessage) 有时我们想要等待一个请求产生的结果,就是发之后等待收, 只需要使用 Requestable 包裹一下客户端,Responsive 包装一下服务端,即可使用请求响应的模式。

使用

import { type Message, Requestable, Responsive } from '../lib';

// 模拟emitter(这个emitter可以是多种多样)
const emitter = {
  callbacks: [] as any[],
  on(topic: string, callback: any) {
    this.callbacks.push(callback);
  },
  off(callback: any) {
    this.callbacks = this.callbacks.filter((c) => c === callback);
  },
  emit(topic: string, message: Message) {
    this.callbacks.forEach((callback) => {
      callback(message);
    });
  },
};
async function bootstrap() {
  const responsive = new Responsive({ emitter: emitter });
  responsive.addRoute('hello', (data) => {
    console.log(`hello data`, data);
    return data;
  });
  responsive.start();
  const requestable = new Requestable({
    emitter: emitter,
  });
  requestable.start();
  const result = await requestable.request({
    url: 'hello',
    payload: {
      1: 123,
    },
  });
  console.log(`result`, result);
  const response = await requestable.request({
    url: 'hhhh',
    payload: {},
  });
  console.log(`response`, response);
}
bootstrap();

server -> like express

route -> wildcard support

// 或者 like trpc server 即 client(类型提醒,直接执行方法)
