# Note: We'd normally prefer to use something like `wasm-pack` as a "production-ready" packager.
# However, when `wasm-pack` runs, it uses `wasm-bindgen` (which ultimately uses webpack 4.X) to
# build the Javascript bindings and thus still suffers from webpack/webpack#7918. Because we use
# the webpack CLI directly here, we benefit from changes in 5.X (specifically,
# the `asyncWebAssembly` experiment).
