Rust Native Module with Node-API
summary
Shows building a native Node module with Node-API and Rust (examples using neon / napi bindings), compiling a Fibonacci function into a native add-on and comparing runtimes: pure JavaScript 22 seconds versus the native module ~6.4 seconds, roughly a quarter of the time. Describes using prebuild tooling to avoid recompiles across Node versions, cautions about bridge overhead (minimize crossings and data copies), and recommends keeping most logic in JS unless heavy compute justifies native code.
