git clone https://github.com/aws-samples/serverless-patterns/cd serverless-patterns/apigw-http-api-lambda-cdk

Deploy

cdk deploy

Testing

Run the following command to send an HTTP GET request to the HTTP APIs endpoint. Note that you must edit the {api_endpoint} placeholder with the URL of the deployed HTTP APIs endpoint. This is provided in the deployment outputs.
curl -H "Origin: https://www.example.com" "{api_endpoint}?path=parameter" --verbose
The output will show a JSON object created by the sample application.

1. In the source folder, from the command line enter:
npx cdk destroy --app 'ts-node .'
2. Confirm the removal and wait for the resource deletion to complete.
