'How do I get input from the DOM and then send a response back in node.js

Basically I'm trying to have the user be able to input something into a form, for it to be sent back to the server so I can then process it and then send back a response that updates the DOM to show the result. I've tried figuring out jQuery and cheerio but I'm just confused and not sure exactly how I can do what I want

i think you must make HTTP Request POST to finish it, i have an article that can guide you, and i hope it helps

Just to get you started:

let data = Object.fromEntries(new FormData(document.querySelector("form")))
fetch(url, {
  body: JSON.stringify(data)
}).then(r => r.json().then(responseData => {
  document.querySelector("p").innerText = responseData.message
}))

Then you have to work out the backend code and adjust what I posted here to suit your needs.
