plaud-mcp: Instructions file for Claude Code

Default to using Bun instead of Node.js.

• Use bun <file> instead of node <file> or ts-node <file>
• Use bun test instead of jest or vitest
• Use bun build <file.html|file.ts|file.css> instead of webpack or esbuild
• Use bun install instead of npm install or yarn install or pnpm install
• Use bun run <script> instead of npm run <script> or yarn run <script> or pnpm run <script>
• Use bunx <package> <command> instead of npx <package> <command>
• Bun automatically loads .env, so don't use dotenv.

Git Rules

• Always create a new branch for each feature or bug fix.
• Always use descriptive commit messages.

APIs

• Bun.serve() supports WebSockets, HTTPS, and routes. Don't use express.
• bun:sqlite for SQLite. Don't use better-sqlite3.
• Bun.redis for Redis. Don't use ioredis.
• Bun.sql for Postgres. Don't use pg or postgres.js.
• WebSocket is built-in. Don't use ws.
• Prefer Bun.file over node:fs's readFile/writeFile
• Bun.$ls instead of execa.

Testing

Use bun test to run tests.

import { test, expect } from "bun:test";

test("hello world", () => {
  expect(1).toBe(1);
});

Frontend

Use HTML imports with Bun.serve(). Don't use vite. HTML imports fully support React, CSS, Tailwind.

Server:

import index from "./index.html"

Bun.serve({
  routes: {
    "/": index,
    "/api/users/:id": {
      GET: (req) => {
        return new Response(JSON.stringify({ id: req.params.id }));
      },
    },
  },
  // optional websocket support
  websocket: {
    open: (ws) => {
      ws.send("Hello, world!");
    },
    message: (ws, message) => {
      ws.send(message);
    },
    close: (ws) => {
      // handle close
    }
  },
  development: {
    hmr: true,
    console: true,
  }
})

HTML files can import .tsx, .jsx or .js files directly and Bun's bundler will transpile & bundle automatically. <link> tags can point to stylesheets and Bun's CSS bundler will bundle.
