Setup & Installation

Prerequisites

• Node.js 14.x or later
• npm 6.x or later
• MongoDB (local or cloud instance)

Quick Start

1. Create a new project using npx:

   npx bootnode my-backend

   This will:

   • Create a new directory called my-backend
   • Set up all necessary files and folders
   • Install all required dependencies

2. Navigate to your project directory:

   cd my-backend

3. Configure your environment variables:

   cp .env.example .env
   # Edit .env with your MongoDB connection string and other settings

4. Start the development server:

   npm run dev

   The server will start on http://localhost:5000 by default.

5. Access the API documentation at http://localhost:5000/api-docs

Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | PORT | Server port | 5000 | | MONGODB_URI | MongoDB connection string | mongodb://localhost:27017/bootnode | | NODE_ENV | Application environment | development | | RATE_LIMIT_WINDOW_MS | Rate limiting window in ms | 15 * 60 * 1000 (15 minutes) | | RATE_LIMIT_MAX | Max requests per window | 100 |

Error Handling

The API returns consistent error responses with appropriate HTTP status codes:

• 400 Bad Request - Invalid input data
• 404 Not Found - Resource not found
• 409 Conflict - Duplicate resource (e.g., email already exists)
• 429 Too Many Requests - Rate limit exceeded
• 500 Internal Server Error - Server error

Example error response:

{
  "success": false,
  "message": "Validation error",
  "errors": ["Email is required", "Name must be at least 3 characters"]
}

Rate Limiting

The API implements rate limiting to prevent abuse:

• 100 requests per 15 minutes per IP address
• Headers included in responses:
  • X-RateLimit-Limit: Maximum requests allowed
  • X-RateLimit-Remaining: Remaining requests in window
  • X-RateLimit-Reset: Timestamp when window resets

API Documentation

Interactive API documentation is available at /api-docs when the server is running. This provides:

• Full endpoint documentation
• Request/response schemas
• The ability to test endpoints directly from the browser

To access the API documentation:

1. Start the server
2. Open http://localhost:5000/api-docs in your browser
