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
