error-handling

The best way to handle recoverable errors is by applying the Either or Result pattern to explicitly model domain versus system errors, promoting safe failure handling and consistent error typing across all application layers.

To classify domain versus system errors during a code review, use a decision framework that categorizes errors based on recoverability, ensuring consistent error typing and explicit recovery paths across the application architecture.

Yes, you can use the Result pattern across languages like Go, Rust, Scala, Java, TypeScript, JavaScript, and Python, applying cross-language best practices to ensure consistent error typing and safe failure handling.

To refactor existing code for explicit error handling, replace broad exception throwing with recoverable error patterns using Either or Result types, clearly classifying domain and system errors to improve code reliability.

You should avoid using the Either or Result pattern for unrecoverable system failures where immediate termination is required, as this pattern is specifically designed to promote recoverable errors and explicit domain error classification.
