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 🙏

一个用来获取/发送斗鱼直播弹幕的工具,目前只实现了获取功能。

兼容 Node 与浏览器环境,Node 环境下会使用 ws 作为 WebSocket 客户端。

使用方式

const danmu = new Danmu({
  // 房间号
  roomId: 301049
  // 弹幕接口
  // wsApi: 'wss://danmuproxy.douyu.com:8503/',
  // 心跳包发送间隔(最多不能超过 45 秒)
  // keepAlive: 40000
})

// connect, disconnect, message, error, rawData, decodeError
danmu.on('message', (payload) => {
  console.log(payload.type)
})

danmu.connect()
danmu.disconnect()

事件

- connect, disconnect, error
  均为 WebSocket 的事件,携带的 event 参考 WebSocket 文档。

- message
  表示接收到新的消息,携带的数据形如 { type: string, xxx: any}
  (不包括解析异常的数据)

- rawData
  表示接收到的新消息的原始形式,携带的数据为 ArrayBuffer 类型
  (不包括解析异常的数据)

- decodeError
  表示解析时发生了异常,携带的数据为 ArrayBuffer 类型

已知问题

目前发现了几种不符合规范的消息:

total@A=15000/num@A=7726/task_id@A=40252/type@A=0/...

parkwavt@=https://apic.douyucdn.cn/upload/avatar/006...

问题分别是将连接符号"@="进行了转义,和未将消息体中的"/"进行转义。

不清楚斗鱼还会整出什么奇怪的格式,所以加入了decodeError事件进行检查。
