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 🙏

Cloud WebSocket server for Mtop DevTools — bridges cloud agents to local connectors

Readme

@mtop-devtools/cloud-server

云端 WebSocket Server,用于中转云端 Agent 请求到本地连接器。

安装

npm install -g @mtop-devtools/cloud-server
# 或
pnpm add -g @mtop-devtools/cloud-server

使用

命令行方式

Server 默认以后台守护进程方式运行,启动后立即返回,并打印本地机器需要执行的连接命令。

mtop-devtools-cloud-server [command] [options]

子命令:

  • start - 后台启动 server(默认,不写也等价于 start
  • stop - 停止后台 server
  • restart - 重启后台 server
  • status - 查看运行状态及连接信息
  • logs - 打印 server 日志末尾

选项:

  • --foreground / -f - 前台运行(不守护化,适合 systemd / Docker / PM2)
  • --port <port> - 服务器端口(默认 8080)
  • --path <path> - WebSocket 路径(默认 /ws)
  • --token <token> - 鉴权密钥(未指定时自动生成)
  • --heartbeat <seconds> - 心跳超时时间(默认 90 秒)
  • --max-connections <n> - 最大连接数(默认 100)

示例:

# 后台启动(自动生成 token),打印连接命令后立即返回
mtop-devtools-cloud-server

# 查看状态与连接信息
mtop-devtools-cloud-server status

# 停止 / 重启
mtop-devtools-cloud-server stop
mtop-devtools-cloud-server restart

# 自定义端口和鉴权
mtop-devtools-cloud-server start --port 9000 --token your-secret-token

# 前台运行(交给外部进程管理器托管)
mtop-devtools-cloud-server --foreground

后台启动后会打印供本地机器使用的连接命令,例如:

[CloudServer] Started in background (pid 12345)
[CloudServer] Logs: ~/.mtop-devtools/cloud-server.log

  Connect from your local machine:
    npx @mtop-devtools/cloud-connector "ws://10.0.1.100:8080/ws?token=xxx"

运行时文件位于 ~/.mtop-devtools/

  • cloud-server.json - 连接配置(含 server URL、pid、端口等),cloud-client 自动读取
  • cloud-server.log - 后台进程日志(logs 子命令读取,或 tail -f 跟踪);超过 5MB 会在下次启动时滚动为 cloud-server.log.1

守护进程的启停、状态、日志滚动等生命周期逻辑由共享包 @mtop-devtools/daemon-core 提供(与 cloud-connector 复用同一套实现)。

关于 token:

  • 未指定 --token 时会自动生成。restart沿用当前 token,因此之前打印的连接命令重启后仍然有效。
  • stop 后再 start 属于全新启动,会重新生成 token;若希望连接命令长期固定,请显式传入 --token 或设置 MTOP_DEVTOOLS_TOKEN

环境变量:

  • MTOP_DEVTOOLS_TOKEN - 鉴权密钥(覆盖 --token 选项)
  • CLOUD_SERVER_HOST - 公网主机名(默认自动获取)

编程方式

import { CloudServer } from '@mtop-devtools/cloud-server';

const server = new CloudServer({
  port: 8080,
  path: '/ws',
  token: 'your-secret-token',
  heartbeatTimeout: 90,
  maxConnections: 100,
  maxMessageSize: 10 * 1024 * 1024,
});

await server.start();

// 获取统计信息
const stats = server.getStats();
console.log(stats);
// { connections: 2, agents: 1, connectors: 1, pendingRequests: 0 }

// 优雅关闭
await server.stop();

架构

云端 Agent
  ↓
@mtop-devtools/cloud-client
  ↓ (WebSocket)
@mtop-devtools/cloud-server (本进程)
  ↓ (WebSocket)
@mtop-devtools/cloud-connector (本地)
  ↓ (Unix Socket)
@mtop-devtools/native-host
  ↓
Chrome Extension / CDP

连接类型

Server 接受两种类型的连接:

  1. Agent 连接 - 发起请求的云端客户端
  2. Connector 连接 - 转发请求到 native-host 的本地连接器

Server 会自动识别连接类型,并将 Agent 的请求转发到可用的 Connector。

消息协议

请求格式(Agent → Server)

{
  "id": "unique-id",
  "action": "get_requests",
  "data": { "count": 5 },
  "version": "1.30.0"
}

响应格式(Server → Agent)

{
  "id": "unique-id",
  "success": true,
  "data": { ... },
  "versionWarning": "..."
}

心跳格式

{ "type": "ping", "timestamp": 1234567890 }
{ "type": "pong", "timestamp": 1234567890 }

鉴权

设置 token 后,所有连接必须携带正确的 token:

# Agent 连接
ws://server.com/ws?token=your-secret-token

# Connector 连接
ws://server.com/ws?token=your-secret-token

部署建议

交给外部进程管理器(systemd / Docker / PM2)托管时,请加 --foreground,让 server 在前台运行,由管理器负责守护与重启。

使用 systemd(Linux)

[Unit]
Description=Mtop DevTools Cloud Server
After=network.target

[Service]
Type=simple
User=your-user
ExecStart=/usr/bin/mtop-devtools-cloud-server --foreground --port 8080 --token your-token
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

使用 Docker

FROM node:20-alpine
RUN npm install -g @mtop-devtools/cloud-server
EXPOSE 8080
CMD ["mtop-devtools-cloud-server", "--foreground", "--token", "your-token"]

使用 PM2

pm2 start mtop-devtools-cloud-server --name mtop-cloud-server -- --foreground --port 8080 --token your-token

注意事项

  • 建议在生产环境使用 WSS(WebSocket Secure)加密传输
  • 使用反向代理(如 Nginx)处理 WSS 升级
  • 设置合理的 maxConnections 限制资源占用
  • 启用 token 鉴权保护服务安全
  • 在沙箱环境中启动时,会自动检测并使用平台分配的公网地址
  • 如果沙箱端口映射 API 不可用,会回退到使用本地 IP 地址
