Storing Images in S3 from Node Server

Learn how to store your web app's files in an s3 bucket. Upload, Download, Update, and Delete images from the s3 bucket.

Uploading an image goes through the express server allowing us to modify the image before it's stored in the s3 bucket. Downloading the image happens directly from the s3 bucket to put less strain on the server and make it easier to integrate our bucket with a CDN in the future.
