To build:

wasm-pack build --target web

This will perform (roughly) the following actions:

• cargo build --target wasm32-unknown-unknown (builds wasm)
• wasm-bindgen (adds wrapper JavaScript bindings around the previously built wasm)
• wasm-opt
• creates a JS package out of the code in the pkg directory

(see https://www.reddit.com/r/rust/comments/kd22u5/wasmpack_dissectionhow_to_work_with_wasmbindgen/)

The advantage is that wasm-pack ensures the wasm-bindgen crate and the command-line tool to generate the bindings are in sync version-wise.

To deploy/run:

Start a Python web server
