Looks neat! Was this developed to solve some internal project? I'm always a little curious when I see open source projects with such fancy landing pages etc that don't mention really what parent org they're from.

What would you say the advantage of this is over Spring Data REST, which automagically configures rest API for repositories (JPA or nosql).

Spring data is obviously a large dependenacy to have on an existing non-spring project, so I can see why this might be useful there. I'm not sure if Spring Data REST is JSON:API compliant but I'm assuming it might not be.

Also, on a side note, side takes 9 seconds to load for me from fresh cache, just a note to dev in case they hadn't realized.
