WebSockets in CDK

CDK doesn't currently have a simple way to create a WebSocket API with API Gateway V2, so I've painstakingly done it from the Cf* primitives, and I hope it's helpful to others.

How to get this running

  • npm install -g aws-cdk Install cdk
  • cdk deploy deploy this stack to your default AWS account/region
  • wscat -c <WebSocketEndpoint> connect to the WebSocket with wscat and the WebSocketEndpoint, which is an output from the CloudFormation stack, and should be displayed on the commandline after a successful deployment
  • Type a message and it should be echoed back to you
