Not sure about this particular instance, but I can tell you about a project I’m working on in C++ that compiles down to wasm. I was working on some prototype code that would eventually run on an embedded device, so C++ was the obvious choice for that work. Getting it all running in a linux app using SDL was a good starting point, but then I needed to collaborate with some very non technical people. At that point using Emscripten to compile the code to run in the browser ended up being useful work. I can upload the resulting html, js, wasm file to a webserver and anyone with a link can take a look. Most of the debugging I do outside of the browser. But I was able to do some debugging using the web inspector. But you’re right. I’m not sure that the tooling is quite there yet for a more generic single page app. My code tends to destroy the browser if left open, and it’s hard to tell why (most likely something memory related that doesn’t translate well). I’m tempted to do more experimenting with cross compiling to wasm, but I’m not sure if my goal was production code on a browser I’d target anything but HTML5 CSS and JS+framework. That said, there’s something to be said to being able produce a webapp while having no direct need for HTML & CSS. In the article author was still using HTML and CSS, so mostly the Rust was to avoid JS. My use case allowed me to not have to know HTML to produce a page. There’s also lots of precedent with game devs using Unity or Haxe tool chains to cross compile to the browser.
