Loading environment variables in Go involves parsing settings like Port, Host, and MongoURI with sensible defaults. This skill handles environment-driven config loading at app startup, validating inputs before wiring dependencies in main.go.

Structured logging in Go microservices is best set up using the slog package. This skill initializes a JSON or text slog logger based on the JSON_LOGS environment variable and provides request logging middleware for production observability.

Yes, you can use slog for JSON logging in standalone Go applications. The skill configures slog to output structured JSON logs when the JSON_LOGS environment variable is enabled, otherwise defaulting to standard text format logging.

Wiring dependencies in main.go for a Go service requires loading environment config like MongoURI and MongoName first. This skill provides patterns to connect MongoDB dependencies, initialize logging, and handle startup errors before serving requests.

Yes, this environment-based config and logging approach works for both microservices and standalone servers. It applies universally to app startup, config validation, logging setup, and dependency wiring across different types of Go services.
