Real-Time Location Tracker

Overview

The Real-Time Location Tracker is a full-stack web application designed to track and display users’ live locations on an interactive map in real time. The application continuously monitors a user’s geographical position using the HTML5 Geolocation API and instantly shares updated coordinates with all connected users through WebSocket communication powered by Socket.IO. Unlike traditional applications that rely on repeated HTTP requests, this project uses persistent WebSocket connections to deliver seamless and low-latency updates without requiring page refreshes.

The project is developed using Node.js, Express.js, Socket.IO, Leaflet.js, and OpenStreetMap. It demonstrates the practical implementation of real-time communication, event-driven programming, and browser-based geolocation services.
