> I don't think sync engines are "the future" although they have their uses

I think the same argument applies to RSC. For many use cases, it doesn't make sense. Many organizations and projects do not need SEO or server code specifically for their FE. If the organization has committed to an API service in order to support a range of clients then RSC/react server framework is "pure overhead."

As someone who has been building with React for a decade, RSC was the moment where I felt the complexity vastly outweighed the benefit. I'm in a position where I can argue that SPAs are dramatically simpler to implement compared to RSC/nextjs, which I think would be surprising to outsiders who bemoan SPAs as complex.

I find the "preload then rehydrate" data synchronization model simpler to understand and can turn even the slowest APIs into an app that feels instant: https://starfx.bower.sh/learn#data-strategy-preload-then-ref...

I'm not trying to get you or anyone to adopt RSC, I'm just trying to explain that if you're bought into the idea that a dedicated backend for your frontend is good (and there are plenty good reasons for people to come to this conclusion), there exists a way to structure the code of that backend that has interesting compositional properties.

I think that's a slightly different kind of message than "servers are unnecessary, peer-to-peer is the future". You can keep servers dumb, but some kinds of product features demand the servers to do the job. And then if you want to squeeze the most out of the server as it relates to your client app, RSC is one way to look at it.

I feel like the design space of making the server as dumb as possible is not sufficiently explored yet. I’m imagining PWAs that work offline by default, hosted on static hosting, talking to CORS-unlocked PKCE-authenticated APIs, storing their state as dumb files in APIs like dropbox, and doing all of the cross-client p2p syncing and merging client-side inside of a service worker.

It wouldn’t work for all categories of software, but so much productivity software ultimately reduces to a per-user file paradigm instead of a central database (outliners, notes, task managers, image editors, …) that I think a lot of complex web apps could be built this way. They wouldn’t work well on low end android phones, but then most of the products from those categories already don’t work well there, when half their logic is still on the server.

And yes, I know, Apple does not play nice with PWAs, but I still think there’s something there that I wish more people would explore.
