## What it is
A Chinese-language troubleshooting handbook for Node.js applications covering online/offline failure diagnosis, load-testing issues, and performance tuning. It is a curated collection of case studies and best practices from the Aliyun Node.js performance platform team.

## Use cases
- diagnose why my node.js app is slow in production
- find and fix memory leaks in node.js
- analyze cpu profiling to improve node.js throughput
- understand garbage collection problems in node.js
- learn how to read core dumps from node.js crashes
- tune node.js app before load testing
- debug a blocked or hanging node.js process

## When to choose
- you run Node.js services in production and need practical debugging playbooks
- you want real-world case studies on memory leaks, GC issues, and CPU bottlenecks
- you prefer Chinese-language documentation for Node.js performance topics

## When to avoid
- you need up-to-date content covering modern Node.js versions and tooling (last updated 2019)
- you want an interactive tool rather than a written guide
- you need English-language documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: monitoring, tracing, benchmarking, developer-tools, documentation
- domain: developer-tools, performance, monitoring, tutorials, backend
- platform: cross-platform
- tags: nodejs, troubleshooting, performance-tuning, memory-leak, cpu-profiling, core-dump, garbage-collection, chinese-language, guide-book
