Logging Errors Effectively in Go Applications

Effective Go application error logging requires balancing details and performance. 1) Using standard log packages is simple but lacks context. 2) logrus provides structured logs and custom fields. 3) Zap combines performance and structured logs, but requires more settings. A complete error logging system should include error enrichment, log level, centralized logging, performance considerations, and error handling modes.

Interface Composition in Go: Building Complex Abstractions

Interface combinations build complex abstractions in Go programming by breaking down functions into small, focused interfaces. 1) Define Reader, Writer and Closer interfaces. 2) Create complex types such as File and NetworkStream by combining these interfaces. 3) Use ProcessData function to show how to handle these combined interfaces. This approach enhances code flexibility, testability, and reusability, but care should be taken to avoid excessive fragmentation and combinatorial complexity.
