VDOM hasn't been needed for a long while, if ever.

You can do a lot better just checking if the template that/s rendering to a spot in the DOM is the same or different from the previous template. If it's the same, just update the bindings from the template, if it's different re-render the whole thing.

That's simpler and faster, but the one thing it leaves out is stateful reordering of lists. So you can have a specific re-ordering code path, which is simpler than a full VDOM, but if you want to preserve state like moveBefore() does, even that reordering gets pretty complicated because you can only preserve state for one contiguous range of nodes that you don't actually move - instead you move all the other nodes around them. moveBefore() just eliminates all that extra complexity.

There's also a couple of standards issues open for native reordering of siblings, like reorderChildren(). That would eliminate the re-ordering code completely.

there's other reasons for the vdom though.

vdom is necessary in react to abstract the view from the platform so it can be represented by react-dom and react-native[-x] bridges.

That has very little bearing on the web platform. I personally don't care for meta-platforms that abstract away the web.

[theultdev]

It does have an impact on app development. I personally don't care for web-only libraries / frameworks.

[spankalee]

I mean that's fine, but when mixed into a conversation on web standards and APIs it leads to a place where you don't care about any web-specific evolution including most progress on the DOM. You end up only caring about a future of WASM + WebGPU, etc. This is exactly where some of the original React core team said they wanted to go - they just wanted a network connected framebuffer.

Again, fine, but I personally prefer a vibrant web platform that evolves to meet the needs of web developers.

[theultdev]

Don't get me wrong, I'm happy for the change. It will improve things overall, and more power to web-only implementations.

My only intent was to point out another function of the vdom being discussed.

For WASM+WebGPU, I doubt it will ever be up to the same accessibility and feel that react-native-web gives. Just look at Flutter.

I'm a web developer and the web api is bloated and ugly. React API is, or at least was, acceptable to work with.

You can still have a framework-specific render tree that maps to the DOM that tracks changes with signals instead of diffing. We’re just saying that there’s no requirement for diffing algorithms anymore to performantly and correctly reconcile state to the DOM. Keyed children was the last place it was needed.
