color me shocked: this is really a rust web framework (compiles to wasm). i was expecting a backend framework that supported react development on the frontend in some non-trivial way. wow. very cool. but i thought wasm couldn't manipulate the dom? is that not the case anymore?

Wasm can't directly, but it can call into JavaScript, which can. That's what this does. DOM support for wasm really means native DOM support, which removes that layer of indirection, and therefore will make it faster.

  i was going to ask if DOM support is on the road map and this comment https://news.ycombinator.com/item?id=13614886 https://news.ycombinator.com/item?id=13614886 claims it is but it's no longer in the high level goals in the spec link is dead... so do you know if it is?

    I don't know where it is on the current roadmap, but there's some activity here: https://github.com/WebAssembly/host-bindings/ https://github.com/WebAssembly/host-bindings/

      weird i tried to post a thumbs up and hn deletes it. is it because it's a single rune? no it doesn't appear in this reply either.

        Aside from the fact that a single thumbs up doesn’t qualify as a comment by HN standards, select Unicode characters are whitelisted but the rest are sanitized.

    Things have been changing, people thought that the DOM stuff would need the GC stuff, but the new "host bindings" proposal my sibling linked to would give DOM stuff without the GC stuff. Everyone I talk to suggests that it will be sometime next year.

It can through a thin bridge. See https://github.com/koute/stdweb https://github.com/koute/stdweb

  so how mature is this tech? is this really feasible? writing browser client code in rust?

      stewed -> stdweb Thanks, autocorrect.

        Yesterday, I learned that the correct term for that is “autoincorrect” thanks to HN.

    If you can write frontend code in typescript or elm, why not rust indeed?

      Those transpile to JS though, not Web Assembly, don't they?

        Javascript and Web Assembly are expected to run on the same engine, if I'm not mistaken.

WASM is just something that can run compiled code in the browser. You can communicate with the Javascript environment. You cannot access the JS libraries directly, but you can with thin bridges. Using such bridges, you can create anything you can with Javascript in any language that compiles to webassembly.
