[tyleo]

This is my approach. My website tyleo.com is just a bunch of CSS/HTML classic webpage stuff. If a page needs a small amount of JS I just bundle it ad-hoc. More complex pages get the full React/SPA treatment but it doesn’t mean the whole website needs to be that way.

As an aside, I reuse code by using React as the template engine for HTML. Each page essentially has a toggle whether to ship it in dynamic mode or static mode which includes the full JS bundles or nothing.
