📦 Install

mkdir express-with-bun
cd express-with-bun
bun init

bun install "@types/express" "express"

Note: bun will install the dependencies in the package.json file just like npm or yarn

This sets up all the requirements

📝 Code

in index.ts add the following code

import express, { Express, Request, Response } from 'express';

const app: Express = express();
const port = 30001;

app.get('/', (req: Request, res: Response) => {
    res.send('Hello world!');
});

app.listen(port, () => {
    console.log(`⚡️[server]: Server is running at http://localhost:${port}`);
});

bun run index.ts

📝 Output
