| description | Use Bun instead of Node.js, npm, pnpm, or vite. Provides command mappings, Bun-specific APIs, and development patterns. |
Use Bun as the default JavaScript/TypeScript runtime and package manager.
| Instead of | Use |
|---|---|
node file.ts | bun file.ts |
ts-node file.ts | bun file.ts |
npm install | bun install |
npm run script | bun run script |
jest / vitest | bun test |
webpack / esbuild | bun build |
Bun automatically loads .env files - don't use dotenv.
Prefer these over Node.js equivalents:
| API | Purpose | Don't use |
|---|---|---|
Bun.serve() | HTTP server with WebSocket, HTTPS, routes | express |
bun:sqlite | SQLite database | better-sqlite3 |
Bun.redis | Redis client | ioredis |
Bun.sql | Postgres client | pg, postgres.js |
Bun.file() | File operations | node:fs readFile/writeFile |
Bun.$\cmd`` | Shell commands | execa |
WebSocket | WebSocket client (built-in) | ws |
Use bun:test for tests:
import { test, expect } from "bun:test";
test("description", () => {
expect(1).toBe(1);
});
Run with bun test.
Use HTML imports with Bun.serve() instead of Vite. Supports React, CSS, Tailwind.
Server:
import index from "./index.html";
Bun.serve({
routes: {
"/": index,
"/api/users/:id": {
GET: (req) => Response.json({ id: req.params.id }),
},
},
development: { hmr: true, console: true },
});
HTML file:
<html>
<body>
<script type="module" src="./app.tsx"></script>
</body>
</html>
Bun's bundler transpiles .tsx, .jsx, .js automatically. CSS is bundled via <link> tags.
Run with bun --hot ./server.ts for HMR.
For detailed API docs, see node_modules/bun-types/docs/**.md.
Rust-inspired TypeScript patterns. Must use when reading or writing TypeScript/JavaScript files.
Creating and maintaining CLAUDE.md project memory files that provide non-obvious codebase context. Use when (1) creating a new CLAUDE.md for a project, (2) adding architectural patterns or design decisions to existing CLAUDE.md, (3) capturing project-specific conventions that aren't obvious from code inspection.
Configure Bun's built-in test runner with Jest-compatible APIs. Use when setting up testing infrastructure, writing unit/integration/snapshot tests, migrating from Jest, or configuring test coverage. 3-10x faster than Jest.
Generates comprehensive documentation explaining how a codebase works, including architecture, key components, data flow, and development guidelines. Use when user wants to understand unfamiliar code, create onboarding docs, document architecture, or explain how the system works.
