Welcome to the JS & Backend Mega Project, a full-featured YouTube-style backend system built with Node.js, Express, and MongoDB.
This project goes beyond simple demos — it’s a production-grade implementation of a modern backend, designed to teach and showcase how real-world platforms are engineered.
It follows industry best practices, a modular architecture, and a scalable codebase, making it a perfect starting point for learning, personal projects, or even enterprise-level applications.
- JWT Authentication with refresh & access tokens.
- Secure Cookie Handling for persistent sessions.
- Role-based Authorization (e.g., Admin, User).
- Password Hashing & Salting with bcrypt.
- Rate Limiting & Security Headers to prevent common attacks.
- MongoDB Integration with Mongoose.
- Robust Schema Design for Users, Videos, Comments, Likes, Subscriptions, and Playlists.
- Aggregation Pipelines for analytics (views, trending videos, etc.).
- Clean & Modular Structure (controllers, routes, services, utils).
- MVC-inspired Pattern for clarity and maintainability.
- Reusable Middlewares for validation, authentication, and error handling.
- Multer-based File Uploads for videos & thumbnails.
- Cloud-ready Storage (easily configurable).
- File Validation (size, type, limits).
- Centralized Error Handling with custom error classes.
- Consistent API Response Wrapper for success & failure.
- Pagination, Filtering & Search support for videos & comments.
- ✅ User Registration, Login, Profile Management.
- 🎬 Video Upload, Edit, Delete, and Publish/Unpublish.
- 💬 Comment System with CRUD operations.
- 👍 Like/Unlike functionality for Videos & Comments.
- 🔔 Subscription System (subscribe/unsubscribe channels).
- 🎶 Playlist Management with Add/Remove videos.
- Environment Variables managed with dotenv.
- CORS Setup for cross-origin requests.
- Helmet.js for HTTP security headers.
- Scalable Folder Structure for enterprise growth.
- Deployment Ready for Render, Vercel, or AWS.
Most tutorials only scratch the surface with basic CRUD apps. This project aims to:
- Replicate real-world complexity of a platform like YouTube.
- Teach scalable architecture instead of spaghetti code.
- Provide a foundation you can extend into a production system.
- Help you master MongoDB aggregations, authentication flows, and middleware design in depth.
