wavyTV Backend

A Node.js-powered backend for a video streaming platform, providing essential features like user authentication, video uploads, playlists, comments, likes, and subscriptions. The project follows a structured approach with controllers handling logic, models managing data, middlewares ensuring smooth processing, and routes defining API endpoints.

The backend is deployed and available at: wavytv-backend.vercel.app
