# tinyconf

> Go config structs filled from a chain of drivers, every package owns its part of the config and gets its changes without restart

tinyconf fills Go config structs from a chain of drivers by struct tags: defaults, YAML, JSON, TOML, INI, properties, environment variables, flags, Consul, Vault and etcd. The next driver overrides the previous one. Packages parse and subscribe to their own parts of the config, reloads create new versions of the config. The module path is github.com/insei/tinyconf/v2.
