📡Creating our API

If we look at the ExpressJS page on NPM, we can find a simple example snippet to help us get started:

const express = require('express')
const app = express()

app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

If we copy this code and paste it into our index.ts file, we can run it using the following command:

bun src/index.ts

After running the command, visit http://localhost:3000 in your browser. You should see a blank page displaying the text "Hello World".
