A scalable and secure RESTful backend service for an EdTech platform, built using Node.js, Express, and MongoDB. This API is responsible for authentication, course management, file handling, and system-level integrations, and is designed to be consumed by any frontend or client application.
Provide a robust backend foundation for an online education platform
Implement secure authentication and authorization
Enable structured course and user management
Design the system to be easily extensible for future business features such as subscriptions, payments, and notifications
Authentication & Authorization
User registration and login
JWT-based secure authentication
Password hashing using bcrypt
Cookie-based session handling
User Management
Role-based access control (Admin / User)
Secure profile handling
Course Management
Create, update, delete, and fetch courses
MongoDB schema-based data validation
File Upload & Storage
File handling using Multer
Cloud storage integration with Cloudinary
Email Integration
Email services using Nodemailer
Designed for verification, alerts, and system notifications
API Health & Monitoring
Health-check endpoint for service validation
Backend Framework: Express.js (Node.js)
Database: MongoDB with Mongoose ODM
Authentication: JSON Web Tokens (JWT)
Security: bcryptjs, HTTP-only cookies
File Uploads: Multer + Cloudinary
Email Service: Nodemailer
Environment Management: dotenv
Development Tooling: Nodemon

Create a .env file in the root directory:
PORT=5000 MONGO_URL=mongodb://127.0.0.1:27017/edtech SECRET=your_jwt_secret
CLOUD_NAME=your_cloudinary_name CLOUD_API=your_cloudinary_api_key CLOUD_SECRET=your_cloudinary_api_secret
Install Dependencies npm install
Run the Server npm run start
Server will run at:
GET /ping
Response:
pONg
User registers → password hashed and stored securely
User logs in → JWT issued
JWT stored in HTTP-only cookie
Protected routes validate JWT via middleware
Modular, layered backend design
Clear separation of routes, controllers, and models
Stateless authentication using JWT
Third-party services abstracted via configuration layers
Designed for horizontal scaling and future microservices adoption
The following features are planned to evolve this backend into a full-scale production system:
Replace basic Nodemailer setup with:
Email templates (HTML-based)
Queue-based email delivery (e.g., background jobs)
Retry and failure handling
Transactional email support (welcome, invoices, reminders)
Integration with payment gateways (e.g., Stripe / Razorpay)
Subscription plans (Monthly / Yearly)
Course-level and platform-level subscriptions
Secure webhook handling for payment status updates
Invoice and transaction history storage
Admin-only dashboard endpoints
User engagement analytics
Course performance metrics
Revenue tracking APIs
Refresh token implementation
Rate limiting and brute-force protection
Role-based permission matrix
Audit logs for sensitive operations
Unit tests for controllers and services
Integration tests for APIs
API documentation using OpenAPI / Swagger
Centralized error handling and logging
API versioning
Caching layer (Redis)
Background job processing (emails, reports)
Deployment-ready configuration (Docker, CI/CD)
This backend is designed to:
Serve as the core API for an EdTech product
Support web and mobile clients
Scale with business and user growth
Act as a strong backend portfolio project
