   • Use route parameters and query strings properly
   • Apply middleware for authentication, validation, or logging

2. Handling Requests & Responses

   • Parse incoming request body, headers, and query parameters
   • Validate and sanitize input to prevent security issues
   • Send structured responses (JSON or XML) with appropriate status codes
   • Handle errors gracefully and return meaningful messages

3. Database Connectivity

   • Use database clients or ORM to connect to your database
   • Perform CRUD operations efficiently
   • Ensure connection pooling and proper error handling
   • Close or release connections when not needed

4. Backend Best Practices
