This is just some Rust + WASM thing I'm messing around with.
The entry point for the wasm is src/wasm.rs.
Build the npm package using wasm-pack.
To build a version that runs standalone and serve it with the basic python webserver:
wasm-pack build -t web
python -m http.server 8000
And open http://localhost:8000/?token=MAPBOX_TOKEN_HERE
