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

***

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

```ts icon="/icons/typescript.svg" title="server.ts"
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).
