AWS Lambda with ClaudiaJS
This document discusses serverless computing using AWS Lambda and the ClaudiaJS deployment tool. It provides an example of building a serverless API with Node.js Lambda functions to interact with a DynamoDB database of ice cream flavors. The API allows creating and retrieving items from the database table. ClaudiaJS is used to deploy and manage the Lambda functions and API Gateway configuration.
