EduZone LMS (MERN)

Production-oriented LMS monorepo with:

• client/ (React + Vite + Redux Toolkit + Tailwind)
• server/ (Node.js + Express + MongoDB + JWT access/refresh auth)

Architecture

Backend (server/src)

• config/ database + env config
• controllers/ request handlers
• models/ mongoose schemas
• routes/ API route modules
• middlewares/ auth, validation, security, error handling
• utils/ token helpers, API response helpers, mailer, misc
• validators/ request validators

Frontend (client/src)

• components/ shared/admin/lms UI
• features/ Redux slices by domain
• hooks/ reusable hooks
• pages/ route-level views
• routes/ route guards + app routing
• services/ axios API client layer
• app/ Redux store

Key Implemented Upgrades

• Access + refresh JWT auth flow (/api/auth/login, /api/auth/refresh, /api/auth/logout)
• Role-based guards (admin, instructor, student)
• Request validation middleware + validators
• Security middleware:
  • in-memory rate limiting
  • request sanitization against Mongo operator injection keys
  • secure default headers
• Centralized success/error response utilities
• Public browse APIs for courses/blogs
• Course search/filter + pagination metadata
• Enrollment ownership checks + student progress update endpoint
• Analytics APIs with real data:
  • GET /api/analytics/admin
  • GET /api/analytics/instructor
  • GET /api/analytics/student
• Frontend axios interceptor with token refresh retry
• Dashboard pages wired to real analytics API data
• Student learning room wired to backend lessons + enrollment progress persistence
