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 🙏

安装

  1. 编译项目:

    deno bundle src/sb-server.ts -o bin/sb-server.js
    deno bundle src/sb-client.ts -o bin/sb-client.js
  2. 安装到 ~/.ssh-bridge/:

    mkdir -p ~/.ssh-bridge/
    cp bin/sb-server.js bin/sb-client.js ~/.ssh-bridge/
  3. 安装 systemd 服务:

    mkdir -p ~/.config/systemd/user/
    cp systemd-user/sb-server.service ~/.config/systemd/user/
    systemctl --user daemon-reload
    systemctl --user enable --now sb-server

协议

协议使用带通道头的逐行 JSON 消息:

channel: { "json": "data" }
  • channel: 通道名称 (不允许包含冒号)
  • { "json": "data" }: JSON 数据

服务端 (sb-server)

  • 在 UNIX socket $XDG_RUNTIME_DIR/ssh-bridge/server 上监听
  • 将收到的所有消息广播到所有连接的客户端
  • 作为 systemd 用户服务运行

客户端 (sb-client)

命令行选项

  • --pub <channel>: 指定要发布的通道 (默认: "default", 可多次使用)
  • --sub <channel>: 指定要订阅的通道 (默认: 全部, 可多次使用)

使用方法

# 订阅所有通道并发布到默认通道
sb-client

# 订阅特定通道
sb-client --sub AAA --sub BBB

# 发布到特定通道
sb-client --pub mychannel

示例

终端 1:

sb-client --sub log

终端 2:

sb-client --pub log
log: {"message": "hello"}
