golang-error-handling

To implement robust error handling in Golang, wrap errors with context and apply a single handling rule. This approach ensures code reliability by using custom error types and structured logging for effective debugging.

Creating and wrapping custom error types in Go involves defining structured data for specific errors and using sentinel errors. This provides clear context for debugging and maintains idiomatic robust code practices.

Structured logging with slog works by integrating error context into your logs, allowing you to track and debug errors effectively. It captures key-value pairs during error wrapping to provide deep visibility into application failures.

You should use panic and recover in Go for truly unrecoverable states rather than routine error handling. This mechanism prevents application crashes by catching panics, ensuring robust code execution when fatal errors occur.

Yes, this error handling approach supports large-scale Go applications by enforcing the single handling rule and structured logging. It maintains code maintainability and reliability across complex systems using custom error types.
