• causeway

  2 825 9.9 Java

  Use Apache Causeway™ to rapidly develop domain-driven apps or modular monoliths in Java, on top of the Spring Boot platform. Write your business logic in entities, domain services or view models, and the framework dynamically generates a representation of that domain model as a webapp, GraphQL or RESTful API. For prototyping or production.

  

Project mention: Hypermedia as the Engine of Application State (HATEOAS) | news.ycombinator.com | 2023-08-01

Apache Causeway [1] generates a RESTful API that is HATEOAS compliant, and exists in parallel to the built-in viewer that is based on Wicket.

There are a few HATEOAS client projects out there, such as [2], that will generate a UI from such a (Restful) API. As far as I know it works quite well, but of course it's a bit rough on the edges.

One interesting observation is that the Wicket UI generated by Causeway does not itself use the RESTful API, but it uses the same meta model that is also used to generate the API.
