AWS Bites

AWS Step Functions are all the rage right now! The visual editor is getting better and better and there are always new capabilities like the recently introduced intrinsic functions. In this episode we will try to answer the question “are Step Functions a Low-Code tool”? In the process, we will give our own definition of what Low-Code means, and we will describe the main characteristics of Step Functions and try to assess whether they match our definition or not. We will also discuss several practical use cases that can be addressed with Low-Code and Step Functions. In this episode, we mentioned the following resources: - Our previous episode dedicated to Step Functions and what can you do with them: https://awsbites.com/7-when-do-you-use-step-functions/ - FullStack Bulletin Newsletter - https://fullstackbulletin.com/ - Implementing the Saga pattern with Step Functions: https://theburningmonk.com/2017/07/applying-the-saga-pattern-with-aws-lambda-and-step-functions/ You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS: https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

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 In this episode we mentioned the following resources: GitHub PR with the final OAuth 2.0 device flow step: https://github.com/awsbites/weshare.click/pull/2 jwtinfo CLI tool: https://github.com/lmammino/jwtinfo enquirer package: https://npm.im/enquirer undici HTTP client package: https://npm.im/undici open package to open the browser at a specific URL: https://npm.im/open ora: animated spinner package: https://npm.im/ora conf package for persisting user settings: https://npm.im/conf You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS: https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

How can you build a WeTransfer or a Dropbox Transfer clone on AWS? This is our fifth live coding stream. In this episode, we continued adding some security to our application. Specifically, we implemented 75% of the OAuth 2 device flow on top of AWS Cognito to allow our file upload CLI application to get some credentials. In order to implement this flow, we need to store some secrets. We decided to use DynamoDB and spent a lot of time discussing our data design and how and why we used the famous and controversial DynamoDB single table design principle. All our code is available in this repository: https://github.com/awsbites/weshare.click In this episode we mentioned the following resources: OAuth 2 Device Auth flow RFC8628: https://www.rfc-editor.org/rfc/rfc8628 The DynamoDB book by Alex DeBrie: https://www.dynamodbbook.com/ LevelDB: https://github.com/google/leveldb OAuth 2 Authorization framework RFC6749: https://www.rfc-editor.org/rfc/rfc6749 You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS: https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

This is our second live coding stream. In this episode, we revisited our architecture and added a custom domain to our APIs, and created a new API endpoint that allows us to have download URLs that are much nicer (shorter and branded). We also added support for the Content-Disposition header to make sure that uploads can specify a file name and that downloads will retain the same file name (regardless of the file key in S3).

In this special episode we announce our next initiative: starting some YouTube coding live streams where we build something on AWS. Specifically we are going to build a file transfer service, just like WeTransfer or Dropbox Transfer! In this episode we announce why we decided to start this, the logistic and some of the details of the product we are going to build. We are really looking forward to pairing with you all live on this build! Make sure you are subscribed to our YouTube channel so you are notified when we go live on Wednesday 17 August!
