What Does THIS Button Do? Serverless and IoT
summary
Builds a serverless feedback app that maps single/double/long click mapping from an AWS IoT One‑Click button to counts stored in DynamoDB; uses two Lambda functions (GET and POST) behind API Gateway, with session ID kept in SSM Parameter Store so the button can’t send the session directly. Uses SAM (including sam local invoke and sam build/package/deploy) and hosts a Vue frontend via Amplify. Buttons are claimed via the console, live clicks increment DynamoDB and the web UI updates; claiming sometimes needs retries but the demo works.
