what is node-lessons fr?

This repository is a Chinese-language Node.js tutorial series titled "Node.js: Guaranteed to Teach You" by alsotang. It is a practical, hands-on course for beginners learning Node.js, the JavaScript runtime that lets you run JavaScript code on a server rather than just in a browser. The course is organized into 18 numbered lessons, each focused on a specific topic. It starts with setting up a development environment, then walks through building a simple web application, using external packages, writing a basic web scraper, handling concurrent operations, writing automated tests, deploying to a hosting platform, working with databases (MongoDB and Mongoose), managing cookies and sessions, and using Promises instead of callback functions. The README notes the course was written in 2015 and some best practices have evolved since then, but the content is still usable because JavaScript maintains backward compatibility. The author wrote it after years of answering questions from Node.js beginners in the CNode community, observing that most people struggled not from a lack of understanding but from a lack of hands-on practice. The course is designed to be progressive, with each lesson building on the last. This would be useful for Chinese-speaking developers who are new to Node.js and want a structured, practical path through the fundamentals rather than a purely theoretical book.
