Completed a Production-Style Video Sharing Platform Backend API
Over the past few weeks, I've been building a backend system inspired by modern video-sharing platforms using Node.js, Express.js, MongoDB, and Cloudinary.
This project went far beyond CRUD operations and helped me understand how real backend systems are designed.
Features Implemented:
✅ JWT Authentication & Refresh Token Rotation
✅ Secure HTTP-Only Cookie Based Sessions
✅ Video Upload & Cloudinary Integration
✅ Comment System
✅ Like System (Videos, Comments, Tweets)
✅ Subscription System
✅ Playlist Management
✅ Watch History Tracking
✅ Creator Dashboard Analytics
✅ Pagination & Aggregation Pipelines
Key Things I Learned:
Authentication using Access & Refresh Tokens
Designing relationships in MongoDB
MongoDB Aggregation Pipelines ($lookup, $group, $project, $addFields)
Ownership-Based Authorization
Cloudinary Media Management
Cascade Cleanup Logic
Building consistent API response structures
Interesting Debugging Challenges:
Duplicate MongoDB index issues
Populate path errors
Refresh token validation flow
Route mismatches
Aggregation pipeline bugs
Watch history synchronization
Video deletion cleanup across collections
Documentation Created:
Complete API Documentation
Authentication Flow Documentation
️ Database Schema Documentation
What's Next?
Building the React frontend and converting this into a complete full-stack application.
