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 🙏

vscode-mcp-ipc

IPC communication layer between MCP Server and VSCode extension.

功能

  • 定义 MCP Server 和 VSCode 扩展之间的事件和数据结构
  • 提供 Unix Socket 通信的封装
  • 支持类型安全的事件调度

使用方法

创建 Dispatcher

import { createDispatcher } from '@vscode-mcp/vscode-mcp-ipc';

const dispatcher = createDispatcher('/path/to/workspace');

发送事件

// 获取诊断信息
const diagnostics = await dispatcher.dispatch('getDiagnostics', {
  uri: 'file:///path/to/file.ts',
});

// 获取定义
const definitions = await dispatcher.dispatch('getDefinition', {
  uri: 'file:///path/to/file.ts',
  line: 10,
  character: 5,
});

// 健康检查
const health = await dispatcher.dispatch('health', {});

// 请求用户输入
const input = await dispatcher.dispatch('requestInput', {
  prompt: 'Please enter your API key:',
  placeholder: 'Enter API key here...',
  title: 'API Configuration',
  password: true,
  validateInput: true,
});

// 执行 VSCode 命令
const result = await dispatcher.dispatch('executeCommand', {
  command: 'editor.action.formatDocument',
});

// 执行带参数的 VSCode 命令
const openResult = await dispatcher.dispatch('executeCommand', {
  command: 'vscode.open',
  args: ['file:///path/to/file.ts'],
});

测试连接

const isConnected = await dispatcher.testConnection();
if (isConnected) {
  console.log('Connected to VSCode extension');
} else {
  console.log('Failed to connect');
}

支持的事件

查看 src/events/index.ts 中的 EventMap 接口来了解所有可用的事件类型和参数。

每个事件都有对应的输入和输出类型定义,确保类型安全的通信。

Socket 路径生成

Socket 路径基于工作区路径的 MD5 哈希生成:

function generateSocketPath(workspacePath: string): string {
  const hash = crypto.createHash('md5').update(workspacePath).digest('hex').slice(0, 8);
  return process.platform === 'win32'
    ? `\\\\.\\pipe\\vscode-mcp-${hash}`
    : path.join(os.tmpdir(), `vscode-mcp-${hash}.sock`);
}
