Realtime Collaborative To-Do List App

This is a simple collaborative to-do list application built using Node.js, Express, and Socket.IO. Multiple users can add and remove to-do items in real-time.

Sockets work in the following way , emitting events to the clients from the server

Features

• Real-Time Updates: Changes made by one user (addition or deletion of a to-do item) are immediately reflected to all connected users.
• Add and Remove To-Do Items: Users can add new to-do items and remove existing ones by clicking on the "Remove" button next to each item.
• Responsive Design: The application is designed to work on different screen sizes, thanks to its responsive CSS.

Technologies Used

• Node.js: A JavaScript runtime used to execute server-side code.
• Express: A web framework for Node.js used to handle HTTP requests and serve static files.
• Socket.IO: A library that enables real-time, bidirectional and event-based communication between web clients and servers.
• HTML/CSS/JavaScript: Front-end technologies used to create the user interface and handle client-side interactions.
