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 and node:https modules that these libraries rely on.

<Note> Refer to the [Runtime > Node.js APIs](/runtime/nodejs-compat#node-http) page for more detailed compatibility information. </Note>

bun add express

To define a simple HTTP route and start a server with Express:

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:

bun server.ts
