CxConfig

CxConfig is an open-source configuration management system and file format designed to simplify the handling of application settings across multiple deployment environments. It provides a declarative, hierarchical model that can be used to describe configuration data for development, testing, staging, and production without duplicating values.

At its core, CxConfig uses a project-wide configuration manifest supplemented by environment-specific overrides. Configs can be composed from multiple files through an include mechanism, and keys may be interpolated from other values or from secret stores. The system supports validation against schemas, cross-file references, and configurable merge strategies to control how values are combined when multiple sources contribute to the final configuration.

Files in CxConfig adopt a language-agnostic syntax and are designed to be serializable to common formats such as JSON, YAML, or TOML. The framework emphasizes profile-based rendering, allowing a single manifest to produce different effective configurations by selecting the active environment or profile at load time. Secret handling can be integrated with vault backends or encrypted fields, reducing exposure of sensitive data.

Tooling and ecosystem: A command-line interface provides validation, merging, and conversion tasks. Language bindings exist for Python, Node.js, and Go, and runtime libraries enable applications to load configuration at startup with optional hot-reloading in long-running processes. CxConfig also offers integration points with container orchestration tools and continuous integration/continuous deployment pipelines to ensure consistent deployment of environment-specific settings.
