Express example

I remember seeing an Express example that does app.listen(3000 but I can’t find it anywhere now. Is there such thing? Where can I find it?

The closest thing I’ve found so far is from


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

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(3000, () => console.log('Example app listening on port 3000!'))

But if I copy it to my notebook, How can I get an URL like

BTW, both the Express end point helper implemented, or the usage example is not working now.

Oh, yeah, the Express example is working now.

As for the Express end point samples, I’ve completely forgot how to verify if they’re working or not now, but, anyway…
