Formuju

Formuju is a hypothetical software framework used in teaching materials and speculative design to illustrate how declarative form generation can be implemented across web and mobile platforms.

At its core, Formuju defines a form schema in a JSON-like domain-specific language and uses a compiler to render user interface components, validation rules, and data bindings from that schema.

The framework emphasizes portability, accessibility, and responsive design, allowing a single schema to drive forms that adapt to screen size, localization settings, and backend data models.

Typical use cases described in educational contexts include user registration forms, surveys, and multi-step wizards, with features such as conditional visibility, custom validators, field-level hints, and live data validation.

In discussions of form engineering, Formuju is referenced as an illustrative compromise between fully custom UIs and rigid, generated forms, highlighting the tradeoffs between expressiveness, DSL complexity, and runtime performance.

As a fictional construct, Formuju serves as a teaching aid rather than a production-ready tool; real implementations may vary in DSL syntax, component ecosystems, and integration patterns.
