## What it is
wasm-pack is a command-line workflow tool for building Rust code into WebAssembly packages that interoperate with JavaScript. It scaffolds projects, builds npm-ready wasm packages, runs browser tests, and publishes to the npm registry.

## Use cases
- compile rust to webassembly for use in javascript
- publish a rust wasm package to npm
- scaffold a new rust wasm project from a template
- run browser tests for rust-generated wasm
- use rust code in a webpack or node.js project

## When to choose
- you write Rust and want to target the browser or Node.js via WebAssembly
- you want an npm-publishable package generated from a Rust crate
- you want a single tool covering scaffolding, building, testing, and publishing for Rust/Wasm

## When to avoid
- your project is pure JavaScript/TypeScript with no Rust component
- you need to compile other languages (C/C++/Go) to WebAssembly
- you want a general-purpose Rust build tool unrelated to wasm

## Facets
- artifact type: cli-tool
- maturity: active
- function: build-tool, cli, wasm, package-manager, testing
- domain: developer-tools, web-development, compilers, frontend
- platform: rust, cli, cross-platform, wasm, browser
- tags: rust-to-wasm, npm-publishing, webassembly, javascript-interop, project-scaffolding, nodejs
