What Hacker News says
4 sourcesHi floodfx, we should chat at some point if you're on slack/discord/etc. I'm building something extremely similar and there's potential opportunity to share some code/learnings. Personally I feel this design paradigm is the real web 3.0.
My project is https://diffhtml.org/ and I have started experimenting with middleware to bridge to server and client workers: https://github.com/tbranyen/diffhtml/pull/251. For the server worker, it uses a WebSocket to ferry the VDOM diff patches, custom events, and property access/function calls. A big goal is to allow synchronous "main thread" access from workers, including on the server-side. This would allow you to write your UI code as if you were a client side app. It does this the same way as partytown using a SharedArrayBuffer and Atomics. You can see demo source code here: https://gist.github.com/

I've also toyed around with hot reloading components without the need for a pre-processor like Babel, and the results are hugely promising. Stateful live UI updates from saving a component file to seeing in the browser without all the fuss with complex build steps is liberating.
I'm probably a few months out from having a usable beta, but I'm going to follow your project closely. Thanks for sharing!
I suggested one such idea (a diffing version of innerHTML) years ago to Mozilla. Ironically, the React team was against it and it fizzled out. In more ironic twists of events, someone eventually wrote a JS implementation of it: https://github.com/tbranyen/diffhtml/tree/master/packages/di... and nowadays people are talking about HTML-based rendering engines again, making this idea somewhat relevant once more.
To be fair to standards bodies, they have done some work. Element.append now exists to make hyperscripts a bit more straightforward, and a lot of reactivity semantics can be implemented on top of Proxy.
