Build a Realtime Notification Feed for AWS S3

The tutorial provides a comprehensive guide on setting up notifications for AWS S3 events using Stream Feed in conjunction with various AWS services like CloudTrail, CloudWatch, and Lambda. It outlines the process of creating a timeline to display events such as uploads, downloads, and views of assets from an S3 bucket. Since AWS does not natively offer notifications for file viewing or downloading, the tutorial demonstrates how to create custom notifications and integrate them with Stream's Notification Feeds. The process involves configuring AWS services to monitor specific S3 events and using a Lambda function to post these events to an app that displays them in a notification feed. Additionally, it includes steps for setting up a Stream client on the frontend using React and Express, allowing users to view these notifications in real-time. The tutorial also touches on how to extend this setup to monitor events from other cloud storage services like Google Drive.
