This isn't academic. When I talk about file descriptor exhaustion, it's because I've debugged it in production. When I explain hidden class transitions, it's because I've seen them destroy application performance.
Blazing-fast Node.js framework with radix-tree router, middleware layer, WebSockets, and performance monitoring. Built without external dependencies.
Long-form, code-along book teaching Node.js by building a backend framework from zero dependencies. Includes exercises and benchmarks.
(Almost) Production-ready logger with rolling file support and tracing primitives. Minimal dependencies for high-performance logging.
Check how strong your passwords really are. Calculates entropy, shows crack times for online and offline attacks, generates secure random passwords, and spots weak patterns like keyboard walks or repeated characters.
Upload any image and convert it to ASCII art. Uses text characters to recreate your photos. Adjust character sets and sizing to get different styles and effects.
We'll be exploring the V8 engine to understand how it compiles, optimizes, and executes our code. We'll get into the weeds on Turbofan, hidden classes, de-opts, and all the stuff that actually controls your app's performance.
This chapter digs into Node.js Buffer allocation. Learn exactly when unsafe allocation is worth the performance gain. By the end, you'll have a crystal-clear mental model for making the right allocation choice every single time.
Senior devs are responsible for applications that don't just run, but survive in production. They master how a process handles OS signals, manages resources, and shuts down gracefully - the critical skills that prevent data loss and 3 AM alerts.
This chapter dives deep into how Node’s runtime, V8, libuv, and microtasks all go hand-in-hand together. You'll never have any questions regarding the event loop after reading this one!
