## What it is
An open-source Chinese-language book analyzing Node.js internals based on Node v6.0.0 source code, covering libuv, V8, the event loop, async IO, and core modules. It is hosted on GitHub and GitBook and aimed at developers with C/C++ background.

## Use cases
- understand how the Node.js event loop works internally
- learn how libuv implements async file IO
- study Node.js module loading internals
- deep dive into V8 and C++/JS bindings in Node.js
- learn how Node.js streams, buffers, and net sockets are implemented
- prepare for Node.js performance tuning and debugging

## When to choose
- you want a source-level explanation of Node.js internals rather than API docs
- you are comfortable reading C/C++ and want to study libuv and V8
- you want to understand async IO and the event loop design philosophy

## When to avoid
- you need documentation for modern Node.js versions (analysis is based on v6.0.0)
- you are a beginner looking for tutorials on building apps rather than internals
- you need an up-to-date maintained reference (content is largely historical)

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: developer-tools, tutorials, backend
- platform: cross-platform
- tags: nodejs-internals, source-code-analysis, libuv, v8, event-loop, book, gitbook, nodejs
