Viper is a configuration management library for Go applications that supports various configuration formats such as JSON, YAML, TOML, and HCL. It enables developers to manage application settings using files, environment variables, flags, remote systems, or default values. Viper simplifies the process of accessing and maintaining configuration data in a structured and consistent manner.

About Viper
Viper was created in 2014 to address the need for a comprehensive configuration management solution in Go applications. It emerged from the Go community's requirement for a flexible and robust library that could handle multiple configuration formats and sources efficiently. The library has since become a widely adopted tool for managing application settings in Go projects.
Viper's strengths include its support for multiple configuration formats, ability to handle environment variables, and integration with remote configuration systems. Its weaknesses are the potential for complexity in large projects and occasional performance overhead. Competitors include libraries such as Go-Config, Koanf, and Envconfig.
