Formily is a schema-driven framework designed for building complex web forms by decoupling business logic and validation rules from the underlying user interface. It utilizes a declarative JSON schema to define form structures, allowing developers to manage data collection and field interactions independently of specific component libraries or frontend frameworks.
The system is built upon a reactive observable state engine that synchronizes form data, validation status, and field interactions in real time. By employing a recursive tree traversal and a centralized event bus, the engine manages granular updates across the form structure, ensuring high performance even in complex, nested layouts.
Beyond its core engine, the project provides a visual builder interface that enables the construction of sophisticated form layouts through drag-and-drop configuration. This approach allows for the standardization of data collection processes and the creation of reusable form definitions across large-scale applications.
