Node.js Backend Roadmap

I am the author and maintainer of a highly-starred open-source Node.js roadmap. It provides a comprehensive, step-by-step guide to mastering backend development—from web fundamentals and TypeScript, to building robust RESTful APIs with Express.

The roadmap features structured weekly modules, curated bilingual resources (Arabic & English), practical assignments, and quizzes covering database architecture (SQL & NoSQL), secure authentication (JWT & OAuth2), and test-driven development.
