Quick Intro to Typescript and CDK

I made this repo to learn how to use AWS CDK

What Problems Does CDK Solve?

Why Not Just Use AWS SAM?

This was actually my first question. The primary answer is CDK doesn't live in a vacuum.

Setting Up Linters For Code Quality

I use a modified functional typescript linter with strict code complexity. Copy and paste the eslint configs from here into your project and use the following shortcut:

npm i -D eslint @typescript-eslint/eslint-plugin @typescript-eslint/parser eslint-plugin-functional

Useful commands(copied from the initial template)

The cdk.json file tells the CDK Toolkit how to execute your app.

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth emits the synthesized CloudFormation template

Notes on DynamoDB tables

• I tried renaming a database, and it didn't look like it transferred data
