It operates as a model-based frontend generator where the server controls the layout and behavior of the user interface through structured data schemas, enabling a low-code approach to web development. The project allows for the definition of visual hierarchies and component properties on the backend, using a JSON-based protocol to communicate UI structure between the server and client. It utilizes schema-driven generation to automate the creation of interfaces, including the automatic construction of input fields and validation logic by mapping data models directly to UI components. The framework covers a broad range of interface capabilities, including declarative layout organization, page navigation management, and data visualization via interactive tables and structured data rendering. It also provides a system for UI state and feedback, rich media embedding, and a mechanism for implementing custom UI components. ## Tags ### Software Engineering & Architecture - [Schema-Driven Generators](https://awesome-repositories.com/f/software-engineering-architecture/schema-driven-generators.md) — Generates complete frontend interfaces by interpreting structured data models sent from the server. - [Automatic Form Generation](https://awesome-repositories.com/f/software-engineering-architecture/schema-based-state-validation/form-validation-schemas/automatic-form-generation.md) — Automatically constructs input fields and validation logic by mapping Pydantic data models directly to UI components. - [Server-Driven Navigation](https://awesome-repositories.com/f/software-engineering-architecture/event-driven-architectures/server-driven-navigation.md) — Implements a routing system for moving between views through server-driven event triggers.
