WARNING! just for fun pet-project, not recommend for production use
conf simplify loading of application settings from different source.
It may be specialized service like consul or etcd or simple json file, cli flags and environment variables.
While you develop, debug or testing your application, you may need to redeclare some of the settings, like database connection parameters, or some domain logic options. conf let you organize application configuration process flexible.
Application config represented as a set of services configs provided or used by application. First you need
to instantiate conf.Provider then add some sources like json-file, environment variables of cli flags.
When sources added you should Load configs you need. conf.Provider will try to load services configs
from each source you've added concurrently. Then you may take service config calling ServiceConfig method.
You will get service config loaded from most prioritized source.
See usage example.
- each source has priority
- each source may provide configs for many services
conf includes components to load data from 3 source types:
- environment variables
- command line flags
- json files
instantiaite provider -> add sources -> load config data -> use config data
You may see detailed example
conf has only one third-party dependency
