Learning CDK and Step Functions

I started with this highly useful but slightly outdated tutorial Create a Serverless Workflow.

I rewrote it in cdk.

Read my post on dev.to.

Now updated to CDK v2!

Useful commands

• npm install do this first
• npm run lint check your style
• npm test perform the jest unit tests
• npx cdk bootstrap the first time only to prep your environment
• npm run deploy deploy this stack to your default AWS account/region
• npx cdk diff compare deployed stack with current state
• npm run synth emits the synthesized CloudFormation template
• npx run destroy removes your stack

Lambda functionss via SAM

• npm run synth to create the template for SAM.
• sam local invoke <FN name from template.yaml> -e ./inputs/<JSON input> to run the function locally.
