Ask HN: What web apps use WASM today?

In 2021, I made my first WASM experiment, an editor for LODA. You can try it here: https://loda-lang.org/edit/?oeis=2487

Getting the Rust code to output wasm was easy. Getting the wasm run in a separate web worker was difficult.

The outputted wasm file is around 1mb. I'm not sure if the outputted wasm file can be compacted. This is the script I use for generating the wasm file. Any ideas? https://github.com/loda-lang/loda-rust/blob/develop/rust_pro...

I'm not sure what flags wasm-pack uses, but you can try using opt-level=s for smaller codegen. Also lto can help.

You can take a look at cargo-bloat. It's sometimes surprising what code takes up all the space.

"surprising what code takes up the space".

Lol, indeed, I will try out your excellent suggestions.

I read something a while back about AutoCAD using WASM.
