Node.js N-API for Rust

on YouTube ↗55m

" summary

Describes using Node.js N-API (the stable C ABI) to write native addons in Rust without tying them to V8, with bindgen and procedural macros generating safe Rust wrappers for raw N-API calls. Shows sharing memory between JS and Rust via ArrayBuffer/TypedArray, using rayon parallel iterators in Rust to compute sum-of-squares, reports a 17× speedup compared to JS, and gives examples that compile with node-gyp or in a Docker development container and run end-to-end.
