How would you design an error handling strategy for a large-scale Go application?

Designing an error handling strategy for a large-scale Go application involves several key principles. First, it's essential to centralize error handling in a middleware or framework component, ensuring consistency in error reporting and handling throughout the application. Second, error propagation should be implemented, allowing errors to flow up the call stack to the appropriate handling point. Third, error messages should be informative but not excessive to avoid clutter. Finally, avoiding the use of panic and recover for all errors is crucial, as these should be reserved for exceptional cases, not for normal error handling. A well-designed error handling strategy contributes to maintainable, reliable, and understandable code in large-scale Go applications.
