Reactpy is a Python web component framework and server-side UI library used to build interactive web interfaces. It allows for the creation of structured web layouts and visual logic within Python, removing the requirement to write client-side JavaScript.
The framework utilizes a component-based model with reactive state management, where the user interface automatically updates in response to changes in the underlying Python state. It employs a virtual-DOM diffing process and WebSocket-based syncing to push real-time updates from the server to the browser.
The system functions as an integration layer that attaches reactive interfaces to existing Python backend servers and web frameworks. This enables the composition of reusable components that manage their own behavior and state through a declarative hierarchy.
