Create an Amazon API Gateway Websocket API that invokes an AWS Lambda function
This pattern deploys an Amazon API Gateway WebSocket API with a $connect route, a $disconnect route and a custom route.
The $connect route invokes an AWS Lambda function to record the WebSocket's connection ID to a DynamoDB table.
The custom route is integrated with an AWS Lambda function written in Node.js which returns back the contents of the "data" node of a JSON object within the request's body. The $disconnect route invokes a Lambda function to remove the connection ID from the DynamoDB table when the WebSocket connection is closed.

Cleanup
1. Delete the stack:
sam delete --stack-name STACK_NAME.2. Confirm the stack has been deleted:
