Welcome to your CDK TypeScript project

This is a blank project for CDK development with TypeScript.

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

Useful commands

• 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

How to Use the Lambda Function?

Before deploying the Lambda function, it's essential to understand how to invoke it:

1. Dry Run: To test the Lambda function without actually deleting any Log Groups, invoke it with the following event:

   { "cleanup": false }

   This will allow the function to identify unused Log Groups and log them without performing any deletions.

2. Actual Cleanup: Once you're confident with the dry run results and want to proceed with the actual cleanup, invoke the Lambda function with:

   { "cleanup": true }

   This will command the function to delete the identified unused CloudWatch Log Groups.

Invoke Lambda function from terminal

aws lambda invoke --function-name YourFunctionName --payload '{"cleanup": false}' outputfile.txt

To see the logs tail you can use the following aws cli command:

aws logs tail /aws/lambda/YourFunctionName --follow

Happy coding ;)
