This is the source for the `flow-web` NPM package, which exposes Javascript/Typescript bindings to Flow library functions in Web Assembly (WASM). The gist is that we compile this Rust crate to WASM and then generate the corresponding JS/TS files using `wasm-bindgen`. We use `wasm-pack` to put everything together into an NPM package that works with Webpack, and publish that to Github packages.
