title: JHipster without JDL
body: <p>I'm quite interested in exploring JHipster in depth since I like the idea of having a framework for generating a spring-microservice backend with modern react/angular. HOWEVER, I'm put off by the fact that JHipster uses its own language 'JDL' -- I don't want to be tied to the-JHipster ecosystem per se, I just want quality boilerplates to work from. What exactly is JDL? Can it be ignored/removed, or does using JHipster mean that you're sucked into learning yet more niche technologies that may or may not survive the test of time?</p>
