Prerequisites

To get started, make sure your credentials are configured. See the ClaudiaJS Getting Started Guide for more information.

AWS Lambda currently runs Node.js version 10 and 8 (you can choose the runtime with --runtime when creating the function). It's best to use the same version for testing and deployment.
