name: Build an HTTP server using Express and Bun
---
Express and other major Node.js HTTP libraries should work out of the box. Bun implements the [`node:http`](https://nodejs.org/api/http.html) and [`node:https`](https://nodejs.org/api/https.html) modules that these libraries rely on.

Refer to the [Runtime > Node.js APIs](https://bun.com/docs/runtime/nodejs-apis#node-http) page for more detailed compatibility information.
{% /callout %}
```sh
$ bun add express
```
---
To define a simple HTTP route and start a server with Express:
```ts#server.ts
import express from "express";
const app = express();
const port = 8080;
app.get("/", (req, res) => {
res.send("Hello World!");
});
app.listen(port, () => {
console.log(`Listening on port ${port}...`);
});
```
---
To start the server on `localhost`:
```sh
$ bun server.ts
```
