What is Viper used for?
Viper is used to manage configuration in Go applications. It allows developers to load settings from various sources such as JSON, YAML, TOML files, environment variables, command-line flags, and even remote configuration systems. Viper supports live reloading, so applications do not need to restart after changes. It centralises configuration management and simplifies switching between environments. That is why Go developers often use Viper for complex applications that require flexible and organised configuration handling.
