Questions tagged [viper-go]

This tag is for questions related to the Go Viper package for reading configuration data from files and other sources.

Viper is a configuration package for Go. It supports reading configuration data from many formats (JSON, TOML, YAML, HCL, or Java properties) and other sources, like environment variables and command line flags, setting defaults and overriding them.
