Waku PPR?

[dai-shi]

According to https://sunilpai.dev/posts/ppr-for-everyone/ by @threepointone, it seems technically possible to implement PPR in Waku.

We could start experimenting it, but to finalize it, the followings are blocking:

• https://react.dev/reference/react-dom/static/prerender should describe about postponed
• unstable_postpone should become postpone, or at least noted it's ready for frameworks
• resumeToReadableStream should be provided from react-dom/server.edge

Meanwhile, I'll focus on #816 which has a different trade-off.

I was planning to test something similar by using an internal request from the edge server to the origin server and try to pipe the response back to the client. I didn't know about this ability for the client to switch origin servers with postpone.

I also noticed this quote in the article:

That said, you may want to do this dynamically in the app at runtime and store these bits in a cache, and maybe revalidate them occasionally

Related to #1212

I'm currently looking at the roadmap for one of the best frameworks

I think this has been unblocked with the release of React 19.2.

There's also prerender from react-server-dom-xxx/static facebook/react#34633. It looks like this is for PPR-ing RSC stream (and there's no resume yet?), so probably not a blocker for PPR-ing HTML stream.

I think this has been unblocked with the release of React 19.2.

I haven't checked closely yet, but are all three check box items covered?

Anyway, we should focus on v1 for now and let's work on this once it's settled.
