Curious, anyone know how this would compare performance wise for something like Reddit verses livewire/liveview. I know those would be more reactive, but I like the idea of static pages that are dynamic as well.

Incremental Static Site Regeneration is really compelling, I wonder what the gotchas are.

For instance, I have a project where the front page gets server-side-rendered for logged out users. We can't do client-side-rendering because we care about SEO. And we can't do static-generation at build time because the content of the front page regularly changes (it summarizes activities of other users).

But with incremental static site generation... even if we care about the community always having up-to-date data on that front page, we could presumably set the timeout to like five seconds. That's a heck of a savings compared to generating it on every request.

I haven't really kept up to date in this area so would love to hear some experts weigh in here: Do search engines (or really just Google) still penalize sites that are pure SPAs on that fact alone?

Or does it have more do do with properties generally associated with SPAs like large bundle sizes or slow time to first interaction?

I'm mainly wondering if you can build a SEO-friendly SPA marketing page today using techniques like dynamic imports and code splitting to lazy load just the scripts and content needed for the initial render instead of going all the way to static generation or server side rendering.

Maybe I'm missing something, but ultimately, isn't this just a re-invention of a site-wide cache?

Back in the day, in Django/Drupal/any CMS, for anonymous users, you'd just dump each page into memcached with a path URL.

Then when a new anonymous visitor comes, you load it right up from – extremely fast – memory. Maybe even faster than loading from the file system? Nginx can actually ask memcached directly, even bypassing the app server.

It feels like we've gone full circle.

I don't know what archetecture your website uses, but our site for example we just cache the view into redis for however long. It's built into a lot of webframeworks, but shouldn't be too crazy to implement by hand.

My take is that it implements the benefits you describe for simple sites that might have less infrastructure at their disposal. It seems like you still need a node runtime to rebuild the files when the cache needs to be regenerated, however.

You're not totally wrong, but think of it this way. You have native support in your application stack for this static 'caching' along with one-click edge distribution. Which means you can write extremely complex, interactive markup (it's just React) on top of this very simple distribution system. And you don't have to build a whole magic caching system or deal with web servers at all.

I've worked with similar systems to the one you've laid out -- tell me you've never had to jump into the cache to clear it because a client wasn't seeing their updates. Or a page was getting improperly cached. Even if it was simple and effective, it was often a pain.

These days, there are a number of services that will store your html and other static files on their edge CDN servers (cloudflare workers, vercel, netlify, among others) leading to your users downloading the files at remarkably fast speeds. You can reach a pretty amazing TTI while maintaining nigh infinite scalability.

I will say that while I personally use next.js, I stick entirely with server-side rendering. I find it to be a better all-around user-experience for my use-case with several distinct advantages. But I only serve ~150,000 users a month, who are all relatively close to my server and I don't have much static content. A modest ec2 instance handles it with ease.

But if I was building an application that targeted many regions and needed infinite scalability, or one that heavily utilized static data, I'd definitely consider pursuing the approach laid out above.

We've gone 'full circle', sure. Because React offered a way to write web applications in a much more consistent, interactive way than anything before it. But we spent a few years growing our bundle sizes out of control, and improperly structuring our applications which led to TTI growing and everything being slow and clunky. Companies that cared and had good engineering were able to navigate these problems, but your average developer couldn't. Now with a system like this, they can not only match the performance of classic applications, but in many cases exceed it.

It's interesting that the React Router team, which is building the competing Remix framework (similar to Next but based on React Router) is arguing that instead of supporting static page generation, they will just urge their users to use CDNs with aggressive caching rules.
