NodeBook explains what happens inside the runtime when your application handles I/O, schedules work, allocates memory, and serves traffic.
Understand poll/check/idle phases, threadpool queueing, and platform differences across epoll, kqueue, and IOCP.
Debug deoptimizations, hidden class transitions, and polymorphic inline cache misses with practical examples.
Implement binary protocols with backpressure-aware transforms, scatter/gather I/O, and external memory management.
Build thread-safe N-API modules, move work through uv_queue_work, and handle memory across JavaScript and C++ boundaries.
Propagate trace context with AsyncLocalStorage, control metrics cardinality, and analyze latency with flamegraphs.
Tune generational GC flags, track retainers in heap snapshots, handle external memory pressure and OOM mitigation.
This curriculum assumes you already write JavaScript regularly. It focuses on runtime behavior, operational tradeoffs, and the details that matter when Node.js runs in production.
Volume I EPUB, light PDF, dark PDF, slides, and cheatsheets are available through /get.
Work execution, data, security, production engineering, and platform architecture follow the networked APIs volume.
Switch between one-reader pricing and team licenses for up to 25 team members.
Volume I as EPUB, light/dark PDFs, slides, cheatsheets, and future updates.
All Labs plus the downloadable Volume I bundle in one purchase. Save $9.99 vs buying separately.
Seven long-form builds: recorder, binary store, stream workbench, resolver, watcher, task runtime, and protocol gateway.
Volume I files, slides, cheatsheets, and updates for a small engineering team.
Node Runtime Labs plus the downloadable Volume I bundle in one team license.
Seven long-form builds for onboarding, study groups, and internal training.
Just wanted to say thank you for keeping this resource free and accessible. Not everyone can afford expensive courses, and this really helps people like me who are trying to learn on a budget.
I've been looking for something that actually explains how Node works under the hood, not just how to use it. This is exactly what I needed. Appreciate you putting this together and sharing it with everyone.
Finally a resource that doesn't assume I already know everything. The explanations are clear and the examples actually make sense. Thanks for taking the time to write this up.
I've worked with Node.js since 2014, building real-time applications, backend services, and performance-sensitive systems that need clear operational behavior.
Many developers use Node.js every day, then get stuck when performance bottlenecks, memory growth, or scaling issues show up in production. My work in Rust and C++ changed how I read Node.js internals, and that systems perspective shapes this guide.
NodeBook comes from years of reading runtime behavior, debugging production issues, and documenting the details that usually stay scattered across source code, docs, talks, and incident notes.
I've always believed that knowledge should be accessible, which is why NodeBook is completely free to read online.
