Automatic static optimization for hybrid applications

[allan2]

It would be great if Yew had something like Next.js's hybrid approach.

They use automatic static optimization. If a page has no blocking data, it's static-generated*. A page can also use SSR or client-side like regular React.

Advantages of hybrid approach:

• performant
• great SEO
• flexible (SSG, SSR, or client-side)

Use cases this would benefit:

• someone who just wants to make a blog using Rust -> full SSG
• someone who wants a blog but also wants to use some external fetched data on particular pages -> mostly SSG, some SSR
• someone who wants a website with landing page. but also an SPA after authentication. -> SSG for the public site, CSR for the authenticated part (although SSR could still be useful here)

I'm not saying we copy everything from them. For example, the filesystem-based router can be omitted.

I do think that the hybrid approach would really open doors for the ways that Yew can be used.

Thoughts?

* #1379 touched on SSG but I opened another issue because this discussion is broader.
