YouTube Clone Project

Introduction This project is a simplified clone of YouTube, developed as part of a Full Stack Development course. The aim is to implement core functionalities of YouTube, focusing on simplicity and scalability, with an emphasis on the learning process rather than building a production-ready system.

Background YouTube is a vast video sharing platform, enabling users to upload, view, rate, share, and comment on videos. Given YouTube's scale, even simple features can be complex to implement. This project primarily focuses on video uploading and viewing.

Features Sign in/out using Google accounts Video uploads for signed-in users Video transcoding to multiple formats (e.g., 360p, 720p) Viewing a list of uploaded videos Watching individual videos High Level Design The architecture incorporates various cloud services:

Video Storage: Using Google Cloud Storage for hosting videos. Video Upload Events: Utilizing Cloud Pub/Sub for managing video upload events. Video Processing Workers: Leveraging Cloud Run and ffmpeg for video transcoding. Video Metadata: Storing metadata in Firestore. Video API: Developing APIs via Firebase Functions. Web Client: Building the client interface with Next.js, hosted on Cloud Run. Authentication: Implementing user authentication through Firebase Auth. Detailed Design

  1. User Sign Up Integration with Firebase Auth for Google account sign-in. Creation of user documents in Firestore for additional user information. Server-side user document creation using Firebase Function triggers.

  2. Video Upload Restricting uploads to authenticated users. Generating signed URLs through Firebase Functions for secure uploads to Cloud Storage.

  3. Video Processing Using Cloud Pub/Sub as a message queue for handling video uploads and processing. Dynamic scaling of video processing workers based on workload. Handling limitations like maximum request timeouts and message redelivery in Cloud Run and Pub/Sub.
