## About

This tool seeks to be a one-stop shop for building and working with rust-

generated WebAssembly that you would like to interop with JavaScript, in the

browser or with Node.js. `wasm-pack` helps you build rust-generated

WebAssembly packages that you could publish to the npm registry, or otherwise use

alongside any javascript packages in workflows that you already use, such as [webpack].
