Service: config

The config service provides a unified interface for managing application configuration. It handles retrieving and setting configuration values, persistent storage, and feature flags.

Interfaces

type Config

Config defines the contract for the configuration service.

type Config interface {
    // Get retrieves a configuration value by key and stores it in the 'out' variable.
    Get(key string, out any) error

    // Set stores a configuration value by key.
    Set(key string, v any) error
}

Standard Implementation

While Config is an interface, the standard implementation typically provides the following functionality:

• Persistent Storage: Saves configuration to disk (e.g., config.json).
• Feature Flags: Checking if specific application features are enabled.
• Defaults: Providing default values for configuration settings.

Common Methods

Although not part of the minimal Config interface, implementations often provide:

• Save() error: Explicitly saves the current configuration to disk.
• IsFeatureEnabled(feature string) bool: Checks if a feature flag is active.
