Idiomatic Go patterns for production microservices include the repository pattern, service layer with dependency injection, domain error handling, and functional options to ensure maintainability and scalability.

Domain error handling and middleware in Go are implemented by codifying standard patterns that separate error logic from transport concerns, enabling consistent error propagation and request processing across service layers.

The best way to write table-driven tests and fake implementations in Go is to follow idiomatic patterns that define test cases declaratively and use fake interface implementations for isolated, maintainable testing.

Configuration loading and graceful shutdown in Go applications are handled using established best practices that safely parse config sources and coordinate context cancellation to terminate services without data loss.

Functional options and worker pools in Go should be used when you need flexible constructor configuration and concurrent task processing, adhering to production-grade code standards for safe concurrent execution.

These Go code standards support reviewing and refactoring existing Go applications by applying modern best practices like the service layer pattern, domain errors, and middleware to improve code quality and structure.
