Express.js

Build Node.js web servers and REST APIs with Express — a minimal, unopinionated framework on top of Node's HTTP module.

Setup

npm install express

import express from "express"
const app = express()
const port = process.env.PORT || 3000

app.listen(port, () => console.log(`listening on ${port}`))

app is the application object: a function that is the request handler (usable in the Node HTTP server) plus the full routing/middleware API.
