This is a special episode recorded live during a live coding session on YouTube (2022-09-28). The audio-only experience might not be the best one, so if you are curious to see the video and enjoy our diagrams and screen sharing, please check this episode on YouTube: https://youtu.be/b-FoqIcOcPw.

How can you build a WeTransfer or a Dropbox Transfer clone on AWS? This is our sixth (and last!) live coding stream. In this episode, we completed the authentication layer for our file transfer application. Specifically, we completed the OAuth 2 device flow on top of AWS Cognito and updated the weshare CLI application to support this new authentication flow. We also added an authorization layer in front of our file upload API.

All our code is available in this repository: https://github.com/awsbites/weshare.click
