Flowable-ui-modeler integration with springboot

Did anyone integrate modeler with springboot? I cannot find any reference to do that…

No, that’s not yet possible out of the box. You could take some inspiration from the rest app integration though, where the rest app endpoints can run embedded from within a Spring Boot application.

What use case are you looking for? What kind of integration are you looking for beyond simply running the webapp from the Spring Boot environment?
