Supler: complex web forms, not so complex
summary
Supler provides a Scala DSL that serializes form definitions to JSON and a Javascript renderer that builds HTML, runs common checks in the browser and posts full state back for backend validation and actions. Demo creates nested subforms, dependent selects, custom validators, templated field layouts and add/delete actions, wires simple REST endpoints and shows persistence logging — the live prototype works end to end and the project is on GitHub under Apache 2.
