response.write() in Node.js

response.write() (in node js) is a Node.js topic. In plain words you use it for a short response.write in node js example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest response.write in node js example you can type. Type it, run it, and say what you see. If you can do that from memory, you know response.write() (in node js).

From the example next to this theory: response.write() in Node.js — http.createServer handles each request with (req, res). Express sits on top of this..

Trap — only saying “response.write in node js” with no example. Fix that before you talk about advanced Node.js.

Viva: what is response.write() (in node js)? Then show the smallest response.write in node js example you can type. Then name the trap.

Exam tip

What is response.write() (in node js)? Show this: the smallest response.write in node js example you can type. Trap: only saying “response.write in node js” with no example.

Example

const http = require("http");

const server = http.createServer((req, res) => {
  res.writeHead(200, { "Content-Type": "application/json" });
  res.end(JSON.stringify({ ok: true, path: req.url }));
});

// server.listen(3000);
console.log("handler ready for", "/api/health");
console.log(JSON.stringify({ ok: true, path: "/api/health" }));
