# Build an HTTP server using Elysia and Bun

[Elysia](https://elysiajs.com) is a Bun-first performance focused web framework that takes full advantage of Bun's HTTP, file system, and hot reloading APIs. Get started with `bun create`.

```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create elysia myapp
cd myapp
bun run dev
```

***

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

```ts server.ts icon="https://mintcdn.com/bun-1dd33a4e/JUhaF6Mf68z_zHyy/icons/typescript.svg?fit=max&auto=format&n=JUhaF6Mf68z_zHyy&q=85&s=7ac549adaea8d5487d8fbd58cc3ea35b" theme={"theme":{"light":"github-light","dark":"dracula"}}
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 full-featured server framework with Express-like syntax, type inference, middleware, file uploads, and plugins for JWT authentication, tRPC, and more. It's also is one of the [fastest Bun web frameworks](https://github.com/SaltyAom/bun-http-framework-benchmark).
