I agree with
@Star-Dust, the documentation is fairly easy to follow. What can be done like Ive planned is just extend on the class that was provided to touch on all the aspects like crud functionality and the subscription functionality you mention, which is rather an interesting point.
Yes its cool that one does not really have to create any back-end using it because its a webserver also in its own right.
I will push more functions and also explain how it works using HttpUtils, but again, as you will note its just reproduction and testing that everything works with b4x, which so far with the first example has been a good go.
If you are in a hurry you can extend the class provided as I will be possibly pushing more posts on that thread based on available time on my side.
Happy coding.
