Configmanager

Configmanager is a software component or library designed to facilitate the management of application configuration settings. It provides a standardized way for applications to load, store, access, and update configuration parameters, which are typically used to control application behavior without requiring code modification. Configmanager typically supports various configuration sources, such as files (e.g., JSON, YAML, INI), environment variables, or command-line arguments.

The primary purpose of configmanager is to abstract the complexity of configuration handling from the application's core logic. Developers can define configuration keys and their expected data types, and configmanager takes care of retrieving these values from the configured sources. This separation of concerns makes applications more flexible, maintainable, and easier to deploy in different environments.

Common features of configmanager include the ability to define default values for configuration settings, validate configuration data to ensure correctness, and reload configurations dynamically without restarting the application. Many configmanager implementations also offer mechanisms for hierarchical configuration, allowing settings to be overridden at different levels, such as application-wide defaults being superseded by environment-specific settings. This pattern is particularly useful in development, staging, and production environments where certain parameters need to differ. The use of configmanager promotes best practices in software development by separating configuration from code.
