Use <code>#[napi(constructor)]</code> for constructors.</li>\n<li>Map Rust errors to JavaScript <code>Error</code> objects via <code>napi::Error</code>. Return <code>Result&lt;T&gt;</code> from all fallible functions.</li>\n<li>Use <code>napi::bindgen_prelude::*</code> for common type conversions. Use <code>Buffer</code> for binary data.</li>\n<li>Support both CommonJS and ESM output. Generate <code>.d.ts</code> type definitions automatically.</li>\n<li>Use <code>#[napi(ts_return_type = \"...\")]</code> for complex TypeScript types the macro can't infer.</li>\n<li>Build with <code>napi build --release</code>. Test from TypeScript/JavaScript using a JS test runner (e.g., Vitest or Jest).</li>\n<li>Async: use <code>#[napi]</code> on <code>async fn</code> for Promise-returning functions. Use <code>AsyncTask</code> for CPU-bound work.</li>\n<li>Keep Node.js wrappers thin — business logic in Rust, JS provides idiomatic API.</li>\n<li>Handle <code>BigInt</code>, <code>Date</code>, and other JS-specific types explicitly.</li>\n<li>Anti-patterns: no panics in napi functions, no blocking the event loop, no manual <code>JsValue</code> manipulation.</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":1268,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
