dualkit

dualkit is a software toolkit designed to simplify the development of applications that operate in two distinct modes. It provides a runtime layer and a set of abstractions that allow a single codebase to support, switch between, and synchronize two configurations, data schemas, and user interfaces. The goal is to reduce code duplication while preserving mode isolation.

Architecture and concepts: The core consists of a mode manager, a data layer with mode-scoped storage, and a UI adapter layer. Modes are declared via manifest files that specify identifiers, permissions, and entry points. The runtime enforces mode boundaries, routes API calls to mode-specific handlers, and can synchronize shared state when appropriate. The design emphasizes modularity, allowing developers to add or modify modes without altering unrelated parts of the application.

Usage and workflow: dualkit can be integrated into various languages through adapters or plugins. Typical workflows include defining two modes such as consumer and admin, implementing mode-specific views and logic, and enabling programmatic or user-initiated switching. It supports testing with mode-specific fixtures and can be paired with feature-flag systems for controlled rollouts. The toolkit aims for clear separation of concerns and predictable mode transitions.

Development status and reception: dualkit is used in projects that require dual-mode behavior, such as administrative interfaces or demo environments. It emphasizes extensibility and consistency across modes, while acknowledging that adding dual-mode capabilities can introduce architectural complexity. Contributors generally focus on providing stable mode interfaces and robust isolation between modes.
