KrakenJS environment configuration for repeatable development setups

Centralized Configuration Management

KrakenJS relies on a configuration-driven architecture using the config package to manage environment-specific settings. The framework supports default.json and environment-specific overrides such as development.json and production.json, but maintaining parity across diverse local development environments remains difficult when secrets or machine-specific paths are required.

Ensuring a repeatable development environment requires balancing committed configuration files with dynamic environment variables without introducing complex nesting that complicates debugging.

Configuration Constraints

• Integration of system environment variables into the JSON-based config hierarchy.
• Prevention of sensitive data leakage in committed configuration files.
• Consistency in service loading across different developer workstations.

What is the recommended pattern for integrating environment variables into KrakenJS configuration files to ensure repeatability across development environments? Which approach best prevents configuration drift when overriding default.json values using external environment variables?
