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 🙏

SSEClient

SSEClient 是一个用于处理服务器发送事件(Server-Sent Events,SSE)的 TypeScript 库。

特点

  • 支持服务器发送事件(SSE)的客户端实现。
  • 提供了详细的错误处理和状态码管理。
  • 支持自定义请求头、请求方法和事件监听。
  • 错误回调中包含错误代码,方便问题定位。

安装

pnpm install sseclient

使用方法

基本使用

import { SSEClient } from 'sseclient'

const client = new SSEClient('https://yourserver.com/sse', {
  headers: {
    CacheControl: 'no-cache',
    Connection: 'keep-alive',
    ContentType: 'application/json',
    Language: 'zh'
  },
  method: 'POST'
})

client.on('open', () => {
  console.log('SSE connection opened')
})

client.on('message', (data) => {
  console.log('Received message:', data)
})

client.on('error', (error) => {
  console.error(`SSE error: ${error.message}, Code: ${error.code}`)
})

client.on('close', () => {
  console.log('SSE connection closed')
})

client.send({ key: 'value' }) // 发送消息

错误代码

错误回调中的 code 属性是一个枚举值,表示不同的错误类型:

| 错误代码 | 描述 | | -------- | ------------------------------------ | | 4001 | 浏览器不支持 SSE | | 4002 | SSE执行错误 | | 4003 | SSE 连接错误 | | 4004 | 未知错误 | | 4005 | 该账号涉及敏感信息较多,已停用24小时 |

事件

  • open: 当SSE连接打开时触发。
  • message: 当接收到消息时触发。
  • error: 当发生错误时触发,错误对象包含 codemessage 属性。
  • close: 当SSE连接关闭时触发。
