How is that 'hybrid'? We've been doing exactly that for literally 20 years. How do you think all the pages like "privacy" or "terms and conditions" or the countless other non-dynamic pages are done?
It's just a website. Doesn't need anything fancy to do it.
Honestly, makes me despair at how over-complicated people make really basic stuff.
Its hybrid because you use 2 separates tools/languages/systems to create parts. You use something like jekyl for static parts and something like node to create services that require dynamic stuff.
Yes, we did it for decades but within single framework such as ruby on rails. This is somewhat different although end result looks the same.
