Every Framework Just Got This AMAZING Next.js Feature

First!

I think that SWR is a pattern that is ok only for blog like content. It won't cut it in any UI where you actually need to keep things up to date (and I think that's most of UIs out there).

I'm confused :) it sounds like what you described is "AWS just got this Vercel feature" but the title is "Astro just got this Next.js feature"

ISR is not the same thing as "stale-while-revalidate" (SWR).
Vercel supports SWR since a while ago (search for 'Serverless Pre Rendering Vercel'). You don't have the same set of guarantees in SWR that you have with ISR. The difference on the surface may look marginal, but digging a little deeper, you can see ISR is better.

When you say full-stack web apps, do you mean full-stack JS web apps? Or is there a benefit to other tech stacks as well? Or maybe the analogy was a bit more on-the-nose than I was thinking and this is only for full-stack coffee script apps.

I love me some stale coffee
