Data.parse() API

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

Smallest example: the smallest Data.parse API example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Data.parse() API.

From the example next to this theory: Data.parse() API — http.createServer handles each request with (req, res). Express sits on top of this..

Trap — only saying “Data.parse API” with no example. Fix that before you talk about advanced Node.js.

Viva — what is Data.parse() API? Then show the smallest Data.parse API example you can type. Then name the trap.

Exam tip

What is Data.parse() API? Show this: the smallest Data.parse API example you can type. Trap: only saying “Data.parse API” 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" }));

Data.parse() API — http.createServer handles each request with (req, res). Express sits on top of this.
