Service Patterns

What problem does it solve?

This Skill addresses the common challenges in backend service development by providing patterns for clean architecture, robust error handling, and efficient data management, preventing common pitfalls like exceptions and N+1 queries.

Core Features & Use Cases

• Result Type Pattern: Ensures services never throw exceptions, returning a Result object for predictable success or failure states.
• Base Service Pattern: Provides a standardized structure for services, including logging and error handling utilities.
• Mapper Pattern: Facilitates the transformation of database entities into domain models.
• Transaction Management: Demonstrates safe handling of multi-step database operations.
• Batch Operations: Illustrates how to avoid N+1 query problems for performance.
• Use Case: Develop a user management service that handles creation, retrieval, updates, and deletions, ensuring all operations are type-safe and errors are gracefully managed.

Quick Start

Implement the BaseService pattern in your new service file to standardize error handling and logging.
