Express web framework
Express is a fast, unopinionated, minimalist web framework for Node.js.
Here's a basic usage example:
const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => {
res.send('Hello World!')
})
app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
})
