Implement Basic Express Server Setup with Configurable Port

Description

Task

Implement basic Express server setup that can listen on a configurable port and provides a basic server structure.

Acceptance Criteria

• Server can start on a configurable port
• Supports environment variable port configuration
• Provides a health check endpoint
• Implements proper error handling
• Supports module and direct script execution

Summary of Work

This pull request implements a robust and flexible Express server setup with the following key features:

Changes Made

• Created modular server configuration with createApp() and startServer() functions
• Implemented environment-based port configuration
• Added a basic health check endpoint
• Supported both direct script execution and module import
• Integrated dotenv for environment variable management

Implementation Details

• createApp(): Initializes Express application with a default health check route
• startServer():
  • Supports optional port specification
  • Falls back to environment PORT or default 3000
  • Provides Promise-based server startup
  • Implements error handling for server initialization

Configuration

• Uses .env for configuration
• Defaults to port 3000 if no port specified
• Logs server startup information
• Gracefully handles server startup errors

Testing Approach

• Modular functions allow for easy unit testing
• Health check endpoint provides basic server verification
• Error handling prevents silent failures during server startup

Acceptance Criteria Met

✓ Configurable port support
✓ Environment variable integration
✓ Basic server structure
✓ Error handling
✓ Logging mechanism
✓ Flexible import and execution methods

Changes Made

• Created modular server configuration functions
• Implemented environment-based port selection
• Added health check endpoint
• Integrated dotenv for environment variable management
• Added error handling for server startup

Tests

• Verify server starts on specified port
• Check health endpoint returns 200 status
• Validate environment variable port configuration
• Ensure error handling works correctly
