The Rust and WebAssembly Book
The official Rust + WebAssembly book, walking you through building Conway's Game of Life in Rust compiled to WASM. It covers the full workflow: setup, wasm-bindgen, JS interop, debugging, profiling, and shrinking binary size. The rustwasm working group just archived the org in July 2025, so this is a historical artifact now.
The Game of Life tutorial is one of the better 'build something real' intros in the Rust ecosystem — you end up with actual working code, not just hello world. The profiling and code-size chapters are unusually practical and cover things most tutorials skip entirely. JS FFI section explains the boundary between Rust and JS clearly, including how wasm-bindgen handles the translation. The reference section on which crates work with WASM is a useful quick-check before you pull in a dependency.
The whole org was archived in July 2025 — the README says so upfront, and the blog post explains why. Whatever you read here may already be out of date with the current toolchain. The tutorial only covers wasm-pack + webpack workflow; no coverage of more modern bundler setups or the wasm component model, which is where the ecosystem is actually heading. Chapters outside the Game of Life tutorial (reference section especially) feel thin and were clearly never finished to the same depth. Travis CI config in a repo marked archived is a minor annoyance but signals how long parts of this sat untouched.
