Real-Time Tracker

A real-time location tracking application that allows users to track and share their live location with others on an interactive map. This app uses Socket.IO for real-time communication and Leaflet for rendering the map.

Features

• Real-time location tracking: Share your live location with others.
• Interactive map: View the locations of other users on a map using Leaflet.
• Socket.IO: Real-time communication between clients and server to broadcast location updates.
• Geolocation: Uses the browser's geolocation API to track and update your position on the map.

Installation

1. Clone the repository:

   git clone https://github.com/AdarshKumarSr/real-time-tracker.git
   cd real-time-tracker

2. Install dependencies: Make sure you have Node.js and npm installed. If not, download and install Node.js.

   Then, run the following command in the project directory to install the required dependencies:

   npm install

3. Start the server: After installing the dependencies, start the server with:

   npm start

   This will start the server on port 3000. You can access the app in your browser at http://localhost:3000.

Project Structure

• app.js: The main server file that sets up the Express server and handles Socket.IO connections.
• views/index.ejs: The EJS template that serves the HTML page with the map.
• public/js/script.js: The client-side JavaScript file responsible for handling geolocation, Socket.IO events, and updating the map.
• public/css/style.css: Custom CSS for styling the map and the page.

Technologies Used

• Node.js: JavaScript runtime used to run the server.
• Express: Web framework for Node.js.
• Socket.IO: Library for real-time communication between the server and client.
• Leaflet: JavaScript library for creating interactive maps.
• EJS: Templating engine for rendering dynamic HTML content.
• Geolocation API: Built-in browser API for getting the user's geographical location.

How It Works

1. When the page is loaded, the map is centered at [0, 0] (global coordinates).
2. The browser fetches the user's current location using the Geolocation API.
3. The user's location is sent to the server via Socket.IO, and the server broadcasts this data to all other connected clients.
4. The map is updated with a marker for each user, showing their current location.
5. If a user disconnects, their marker is removed from the map.

Future Improvements

• Add user authentication so that users can have unique IDs and track each other more easily.
• Persist location data in a database for tracking users over time.
• Add a notification system to notify users when others enter or leave their vicinity.
• Optimize the app for mobile devices for better performance and usability.
