- Use Bun instead of Node.js, npm, pnpm, or vite. Provides command mappings, Bun-specific APIs, and development patterns.
Bun Runtime
Use Bun as the default JavaScript/TypeScript runtime and package manager.
Command Mappings
| 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.
Bun-Specific APIs
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 |
Testing
Use bun:test for tests:
import { test, expect } from "bun:test";
test("description", () => {
expect(1).toBe(1);
});
Run with bun test.
Frontend Development
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.
