Building a Countdown Timer with Socket.io

This article is a technical tutorial demonstrating how to build a real-time countdown timer application using Node.js and the Socket.io library. It covers setting up the server-side logic to decrement and broadcast a timer value, handling client-side events like reset, and updating the DOM in real-time. The post is part of a series and discusses deployment considerations and potential issues like latency with xhr-polling.
