Cool post! I'm curious how big your wasm file ended up being?

For node, it would be interesting to compare performance, weight, and gotchas of the wasm approach vs. building a shared library with Rust and then pulling it in through node-gyp. Loading wasm is certainly a lot simpler, but multithreading support seems shaky and I imagine there may be some other drawbacks compared compiling into node directly, despite the added complexity.
