A thread-safe, generic in-memory cache with TTL support, periodic cleanup, and concurrent map access. It is self-contained (uses only stdlib), making it easily extractable into any Go project that needs a simple cache.

A memoized ID normalizer that handles Traefik provider suffixes and auth cascades. It is a standalone utility with no internal dependencies, demonstrating a clean caching pattern for string transformation.

A JSON decoder that can parse both arrays and maps into the same target type, useful for APIs that return inconsistent formats. It is a generic helper that can be reused in any Go project dealing with irregular JSON.

A singleton HTTP client pool with configurable timeouts, connection limits, and keep-alives. It abstracts the net/http client configuration, making it reusable for any project that needs optimized HTTP connections.

A set of standardized error types and response helpers for a REST API. It defines HTTP status codes and error structures that can be extracted and used in any Go web service to ensure consistent error responses.

A registry of type-specific middleware processors that normalize Traefik middleware configuration values (e.g., converting float64 to int, string to bool). Demonstrates a clean strategy pattern for handling polymorphic types, reusable for any config normalization task.
