Cool to see more people digging into Rust + Emscripten.

Not sure why the guide is using nightly Rust, stable has worked pretty well on Emscripten for a while. If you need to pass custom linker flags(which emscripten sometimes requires) you can do it via rustflag directive in .cargo/config.

We've been using Rust + Emscripten for some cross-platfrom targets(web, win32, osx, android and linux) and been pleasantly surprised with how straightforward+stable it's been.

It's in a bit of a transition; we're planning on using LLVM's backed for wasm, and I believe that's landed in nightly[1]. Stable has support but through emscripten's LLVM patches. So maybe they wanted to try out the new stuff, or maybe they didn't know that it was on stable already.

Hi, author here. Thanks for the tip, I wasn't aware compiling with Emscripten would work on stable. That should simplify the process. I'll do some more research and update the guide.

Yeah, was a great article, kudos for that. To be clear I didn't mean it as a criticism just wanted to throw it out there so other people knew that it works on stable.
