Using WebAssembly to turn Rust crates into fast TypeScript libraries

Why fast?<p>In our experience, the cost of boundary-crossing between wasm and js make it slower than js implementation for everything dom-related.

Nice post! We&#x27;re compiling Rust to Wasm for a numerical optimizer and got an order of magnitude speedup compared to our previous TypeScript implementation. It was tricky to get all the build pieces working together though.<p>Our team just uses wasm-bindgen though, and not wasm-pack; curious how much additional value you get from the latter? I could be mistaken but my impression is that wasm-pack uses Webpack; we&#x27;ve generally been trying to use esbuild instead (to make build times faster) but I haven&#x27;t used wasm-pack beyond running the tutorial so maybe I don&#x27;t know what I&#x27;m missing.

Nice writeup! A small improvement: There is `#[serde(rename_all = &quot;camelCase&quot;)]` to avoid typing all properties twice.

I have a need to create 1 library that can be reused in JVM, NodeJS&#x2F;TS, Python, Go.<p>I remember reading something about doing something similar to this but it creates libraries for multiple languages. Have you done something similar before or do you have an idea where to look?

That&#x27;s really cool! Just saved to home screen for when I need to compile something to wasm
