wasm-pack is a tool for assembling and packaging Rust crates that target WebAssembly. These packages can be published to the npm Registry and used alongside other packages. This means you can use them side-by-side with JS and other packages, and in many kind of applications, be it a Node.js server side app, a client-side application bundled by Webpack, or any other sort of application that uses npm dependencies.

We’re recording a show with Lin Clark today and will definitely ask her all about the progress Mozilla folks have been making on merging the JavaScript and Rust worlds via WebAssembly. Exciting times!
