Introduction to native extensions
summary
Explains how to build Node native addons using binding.gyp and node-gyp, and how to use N-API or nan plus worker threads to move CPU-heavy work off the main event loop. Presents an experiment processing 30k items showing performance differences: ~16 req/s with naive workers, ~67 req/s using object instances, and ~274 req/s using buffer/shared memory, while noting the need for explicit binary builds, manual memory management, and careful integration to avoid blocking and unsafe access to JavaScript.
