Level 22: Generate Identifiers

• Assign a unique id to each new record (e.g., incrementing counter or crypto.randomUUID()).
• Return the id with both reads and creates so future levels can reference it.
• Keep in mind: You’re working with your own resource type, so adapt variable names accordingly (not itemsStorage).

Show Me: generate unique identifier

import { randomUUID } from 'node:crypto';
const newItem = { ...req.body, id: randomUUID() };
itemsStorage.push(newItem);
res.status(201).json(newItem);
