How minhsuy/e-learning_server works

This repository is the TypeScript/Express backend for an e-learning platform. Students and teachers use its API to discover and manage courses, enroll, study lessons, track progress, and take quizzes; the platform also supports orders, certificates, notifications, and real-time chat. Routes dispatch requests to controllers and services, with MongoDB models holding domain state. Socket.IO handles live messaging and call signaling. The README documents several capabilities whose detailed implementation was not sampled, so those branches are shown at subsystem level; edges are limited to documented or indexed relationships.

Main entry points: index.route.ts API route registry · order.service.ts Orders and coupons · pdfGenerator.ts Certificates · course.model.ts Course catalog
