Newsletter martinmueller.dev 2022 week 20

In this weekly newsletter, I write a summary of posts that got my attention during the week. I center around topics AWS, DevOps, Architecture, AWS CDK, Data Engineering, Data Analytics and much more.

If you like my content follow me on my usual spots to hang around:

Improve DX by publishing an API SDK - a CDK Serverless example

https://www.rehanvdm.com/blog/improve-dx-publishing-an-api-sdk-cdk-serverless

Uii an API SDK is a nice idea. For me, that looks similar to OpenAPI / Swagger SDKs. It seems to be a smart combination of OpenAPI SDK and TypeScript. Plus with a sophisticated CI/CD flow like posting to slack you can make developers earlier aware of SDK changes. Interesting idea please read the full article!

Thanks a lot to the author Rehan van der Merwe

Getting started with testing DynamoDB code in Python

https://dev.to/aws-builders/getting-started-with-testing-dynamodb-code-in-python-dif

Interesting post about testing DynamoDB code in Python. You can use the python package moto to mock the AWS Service. That is super cool and how I used to when I am working with jest in TypeScript. Super cool that Python has something similar :). So I recommend reading the full article if you are interested in programming AWS CDK or AWS SDK with Python.

Thanks a lot to the author Maurice Borgmeier

How to work around CloudFormation circular dependencies

https://theburningmonk.com/2022/05/how-to-work-around-cloudformation-circular-dependencies/

Super interesting. CloudFormation circular dependencies are an often encountered problem when working with CloudFormation or with AWS CDK (which is basically CloudFormation). So this article is super useful for how to resolve those.

Thanks a lot to the Serverless Hero Yan Cui

Source Control your AWS CloudFormation templates with GitHub

https://dev.to/techielass/source-control-your-aws-cloudformation-templates-with-github-8im

This is a cool article about how to manage your CloudFormation template via GitHub Actions like linting and more. But yeah I would recommend not using CloudFormation directly and using AWS CDK :).

Thanks a lot to the author Sarah Lean

ESLint and Prettier

Open Source Projects

In this section, I list Open Source projects I find super interesting!

json-schema-to-typescript

https://www.npmjs.com/package/json-schema-to-typescript

Import TypeScript type from JSON. That was always a disadvantage when a client wanted me to use a JSON file as input for CDK properties. It is super cool that it seems you easily can infer the type.
