Usually, I use the classic starter one.
Expressjs.com

const express = require('express')
const app = express()
const port = 3000

app.set('view engine', 'ejs')
app.use(express.urlencoded({extended: true}))
app.use('/', router)
app.listen(port, () => {
    console.log(`This is ${port}`)})

When you use the res.render('anyClassViewName') , Express will search for any .ejs file in your views directory and then render it.

Express.urlencoded is made to handle urlencoded payloads. You can use the { extended: true } option for dealing with any complex objects, arrays, and nested objects, or you can set it to 'false' for simpler data parsing.
