Express.js

Node.js

Technical Specification

Move /items routes into a separate router module and mount it under /api/items.

Input/Output Samples

Output:Handled by router

Optimal Logic Path

// items.routes.js
const express = require("express");
const router = express.Router();

router.get("/", (req, res) => res.json([]));
// other item routes...

module.exports = router;

// in app.js
const itemsRouter = require("./items.routes");
app.use("/api/items", itemsRouter);

Architectural Deep-Dive

Routers keep code modular and easier to maintain for large APIs.
