Oh that's fun! In my demo video [1], I build a (minimal) HN clone so hopefully that answers your question in detail.

But the tldr is - you'll need a lot more than just templating for a production ready app. To name a few things - server, storage, migrations, logging, configs. IMO there's a huge benefit in having a batteries included toolkit that stays close to the stdlib - so you can totally keep your templates as is!
