Welcome to the community.
There are some examples … just search for “fetch” or “JSON” on the forum. In general Hype provides a container for your JS code … meaning you will need to manage data distribution or even data binding yourself. But it is possible but requires a little code knowledge. The good thing is that the knowledge isn’t that Hype specific so what you learn applies to the general web, too.
I wrote some code that binds “dataset” keys to class names called Hype DataFill but that might be to advanced to start?! Either way… happy Hyping!
