error-handling

To check wrapped errors in Go, use `errors.Is` to compare against sentinel values and `errors.As` to extract custom error types. These standard library functions provide effective error inspection for wrapped chains.

To wrap database errors with request context in a Go web service, apply error wrapping patterns to add contextual information to the original error. This technique makes debugging significantly easier by tracing the error's origin.

Yes, you can handle multiple errors and propagate them in Go by following established error handling best practices. This includes managing error propagation across function calls and addressing multi-error scenarios effectively.

Best practices for error handling in Go goroutines involve propagating errors safely back to the caller without causing deadlocks. This ensures concurrent operations fail gracefully and maintain application stability.
