A Go library that populates struct fields from environment variables using struct tags. It supports required fields, defaults, prefixes, nested structs, and lookup mutations such as secret resolution.
Use cases
- parse environment variables into a Go config struct
- load app configuration from env vars with defaults
- require certain environment variables at startup
- populate nested config structs with env prefixes
- resolve secrets from a lookup function during config loading
When to choose
- you want declarative, struct-tag-based env config in Go
- you need defaults, required fields, or prefixes for shared config
- you want a small, focused, well-maintained library
When to avoid
- your configuration comes from files or remote sources rather than env vars
- you need complex validation beyond simple required/default handling
