[Elysia](https://elysiajs.com) is a Bun-first web framework built on Bun's HTTP, file system, and hot reloading APIs. Get started with `bun create`.

```bash terminal icon="terminal"
bun create elysia myapp
cd myapp
bun run dev
```

***

To define an HTTP route and start a server with Elysia:

```ts server.ts icon="/icons/typescript.svg"
import { Elysia } from "elysia";

const app = new Elysia().get("/", () => "Hello Elysia").listen(8080);

console.log(`🦊 Elysia is running at on port ${app.server?.port}...`);
```

***

Elysia is a server framework with Express-like syntax, type inference, middleware, file uploads, and plugins for JWT authentication and tRPC. It's one of the [fastest Bun web frameworks](https://github.com/SaltyAom/bun-http-framework-benchmark).

See the Elysia [documentation](https://elysiajs.com/quick-start.html).
