> I [..] could never get the performance or package size to a good place. Do you have any more details on that? I'm curious how close this got, and what were the main issues (on both size and speed).

I don't have specific info, but generally: - VDOMs in general have poor performance; they perform unnecessary computations in the diffing algorithm, and even well-designed ones perform extra DOM manipulations, compared to deliberately-written code. - The Rust WASM files would come out pretty large; a few hundred KB for a minimal app. This is better than some packages using React + common JS dependencies like Lodash and Moment, but with much room for improvement - DOM manipulation calls made in Rust via WASM(currently!) don't have any performance benefit over the native JS API

  It sounds like you made a Rust version of React. I think a Rust version of Svelte makes more sense in the long run.

    Accurate, and I agree.

    At one point I prototyped a wasm framework inspired by Solid[1]. The results were very promising—an implementation of js-framework-benchmark was 41KB (18KB gzipped), and perforrmance was close to vanillajs. The developer ergonomics were definitely lacking, though. Benchmark results (look for "cope")[2][3] I definitely think whatever happens over the next few years, VDOMs are on their way out.

    Sycamore looks interesting, though it needs some more ergonomic improvements before it becomes more widely usable. https://github.com/sycamore-rs/sycamore https://github.com/sycamore-rs/sycamore

      Hi, author of Sycamore here. What kind of ergonomic improvements are you thinking about? If this is something actionable, it would be great if you could open a new issue on our repo.
