I'm trying to understand how this tutorial works, I noticed it doesn't make any network requests when run one of the examples, but then if I edit the code in an example it does make a request. Is this the magic of next.js and server-side components at work, and do you have a real edgedb running on the server side that is used to pre-render the page and also handle updates? I would love to hear more about how this setup works and even look at the code if it's available.
