## What it is
A Chinese-language open-source tutorial by iKcamp for building real-world Node.js projects with the Koa2 web framework. It is organized as a step-by-step course with accompanying articles, videos, and per-lesson source code branches covering middleware, routing, templating, static assets, logging, and error handling.

## Use cases
- learn koa2 from scratch
- node.js backend tutorial for frontend developers
- how to write koa middleware
- koa2 routing with koa-router example
- serve static files and templates in koa
- handle errors and logging in a koa app
- understand async await in node.js web apps

## When to choose
- you are a frontend developer wanting to learn Node.js backend development
- you prefer structured lessons with articles, videos, and incremental code branches
- you want a Chinese-language Koa2 course based on a real production project

## When to avoid
- you need an up-to-date tutorial reflecting the latest Koa or Node.js ecosystem (last updated 2019)
- you want production-ready boilerplate rather than learning material
- you need English-language documentation
