Todo REST API with Node.js (No Framework)

This project is a simple Todo REST API built using Node.js core modules (http and url) without any external frameworks like Express. It demonstrates basic CRUD operations (Create, Read, Update, Delete) for managing todo items in memory.

Features

• List all todos
• Get a specific todo by ID
• Add a new todo
• Update an existing todo
• Delete a todo

API Endpoints

Get all todos

• GET /todos
• Response: Array of todo objects

• The server returns appropriate error messages for invalid requests.
