Realtime Device Tracker Backend

This is the backend server for the Realtime Device Tracker application. It provides real-time tracking of devices using a Node.js server with WebSockets (socket.io) for real-time communication and Express for handling HTTP requests. The server integrates with a Leaflet-based frontend for rendering maps and displaying tracked devices.

Features

• Real-time device tracking using WebSockets (socket.io).
• Backend server with RESTful API endpoints for device data.
• Integration with Leaflet.js for map rendering and tracking devices on the frontend.
• Scalable backend architecture using Express.js and Node.js.

Technologies

• Node.js: Server-side JavaScript runtime.
• Express: Web framework for building the backend.
• Socket.io: For real-time, bidirectional communication between the client and server.
• Leaflet.js: JavaScript library for interactive maps (used in frontend).
• EJS: Embedded JavaScript templating engine (for serving views).

Prerequisites

Before running this project, make sure you have the following installed:

• Node.js (v14+ recommended)
• npm (Node Package Manager)
• Git

Installation

1. Clone the repository:

   git clone https://github.com/Explore13/Realtime-Device-Tracker-Backend.git
   cd Realtime-Device-Tracker-Backend

2. Install dependencies: Make sure you are in the project root directory and install the required dependencies using npm:

   npm install

3. Set up environment variables (Optional): Create a .env file in the project root to configure environment variables, such as port or database credentials (if applicable).

Running the Application

1. Start the server: To run the server on localhost, use the following command:

   npm start

2. Access the app: Open your browser and navigate to http://localhost:3000. The backend will start on port 3000 (or whichever port you set in the environment).

3. Real-time tracking: Open multiple browser windows to test real-time tracking of devices on the map.

WebSocket Events

The server communicates with clients via WebSocket (Socket.io) events.

• connection: When a new user connects to the server.
• send-location: Clients emit this event when they send their latitude and longitude data.
• receive-location: The server emits this event with the user’s ID and location details to all connected clients.
• disconnect: When a user disconnects from the server.
