Sri Lanka Railways GPS Data Generator

This Node.js application simulates GPS data for 10 trains operating on 3 routes in Sri Lanka. It generates and transmits GPS data at one-minute intervals to the sri-lanka-railways-location-api, enabling real-time location tracking.

Features

  • Simulate real-time GPS data for 10 trains across 3 major routes in Sri Lanka.
  • Transmit GPS data to the backend API at one-minute intervals.
  • Configurable transmission interval through environment variables.

Prerequisites

  • Node.js (v14 or higher)
  • npm (Node Package Manager)
  • MongoDB (for train data storage)

Installation

  1. Clone the repository:

    git clone https://github.com/your-username/sri-lanka-railways-gps-data-generator.git
    cd sri-lanka-railways-gps-data-generator

  2. Install dependencies:

    npm install

  3. Set up environment variables:

    BACKEND_API_URL=http://localhost:5000/api/v1
    INTERVAL_MS=60000  # Interval for GPS data transmission (in milliseconds)
    MONGO_URI=mongodb://localhost:27017/railways  # Connection string for MongoDB

  4. Start the application:

    npm start

Configuration

  • BACKEND_API_URL: The URL of the backend API where GPS data is transmitted.
  • INTERVAL_MS: The interval (in milliseconds) at which GPS data is generated and transmitted. Default is 60000 ms (1 minute).
  • MONGO_URI: The connection string for the MongoDB database that stores train data.
