You Don't Know Node.js
summary
Dives into concrete Node.js mechanics with runnable examples: readFileSync vs readFile shows blocking behavior, streams process an 8MB infographic so streaming endpoint returns far faster, and buffers hit limits around gigabyte-sized files. Demonstrates process/global APIs, event emitters for composable callbacks, scaling with PM2 vertical scaling and cluster/master-worker, handling async errors with process uncaughtException and domain, and building C++ addons via node-gyp configure and build to expose native methods.
