    What is ItsyUI?

    ItsyUI is a,

    • State Management library, it is simple and scalable.
    • Opinionated framework of sorts.
    • Set of rich UI components specifically designed for metadata driven UI.
    • Packged with readymade features targeting web, ios, android and pwa apps.

    Future-Proof Architecture

    ItsyUI has generally 3 high-level layers,

    1. Shell Widgets - Written in pure ReactJS + Finite State Machines (FSM with xstate), and defines the behavior of a widget.
    2. UI Widgets - The UI layer forms the way a widget is rendered on screen and only deals with UI and Styling of the widget.
    3. Framework Bindings - Configuration based bindings that allow to define UI flows and its behavior as simple JSON configuration. This allows for reusable configurations, for ex: Invoking a REST API on FORM SUBMIT event.
