Dissecting wasm_build.sh - A deep-dive into every step of the wasm build process
(experimental / draft) Wasm API

Bare Metal WASM is a truly excellent article on writing absolutely tiny no-std wasm, and then loading and using it directly, without wasm-bindgen. All the steps and examples are very easy to follow along with, and the demo-project produces some pretty cool results. It cleared up a lot for me on how this stuff works under the hood.
wasm-pack is a more-opinionated wrapper around wasm-bindgen, that churns out entire npm packages.
