AWS Lambda Powertools for TypeScript examples in CDK

This is a deployable CDK app that deploys AWS Lambda functions as part of a CloudFormation stack. These Lambda functions use the utilities made available as part of AWS Lambda Powertools for TypeScript to demonstrate their usage.

You will need to have a valid AWS Account in order to deploy these resources. These resources may incur costs to your AWS Account. The cost from some services are covered by the AWS Free Tier but not all of them. If you don't have an AWS Account follow these instructions to create one.

The example functions, located in the src folder, are invoked automatically, twice, when deployed using the CDK construct defined in src/example-function.ts. The first invocation demonstrates the effect on logs/metrics/annotations when the Lambda function has a cold start, and the latter without a cold start.

Deploying the stack

• Navigate to this location of the repo in your terminal (examples/cdk)
• npm ci
• npm run cdk deploy --all --profile <YOUR_AWS_PROFILE>

Note: Prior to deploying you may need to run cdk bootstrap aws://<YOU_AWS_ACCOUNT_ID>/<AWS_REGION> --profile <YOUR_AWS_PROFILE> if you have not already bootstrapped your account for CDK.
