Guthrie

A Decarative UI Runtime Engine powered by React.

• Declarative UI Composition
  Build complete user interfaces using structured configuration instead of imperative code. UI, logic, and behavior are defined in a unified declarative model.

• Runtime Expression Engine
  Evaluate dynamic expressions using extensible operators. Compose logic directly in your configuration without embedding JavaScript.

• Function & Event Orchestration
  Execute functions and attach events declaratively. Combine async logic, side effects, and UI updates without tightly coupling them to components.

• Fully Extensible Architecture
  Customize elements, operators, and functions to adapt Guthrie to your domain. The system is designed to be extended, not constrained.
