Description

Enabling CORS via the Web UI is easy: http://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-cors.html what we need is a way to do it using the aws-sdk so that we can deploy our API with a single command.

Research direction
Research the AWS SDK for JavaScript (apigateway) to find methods for enabling CORS on API Gateway endpoints. Check the existing code in the repository (e.g., any deployment scripts) and the single comment on the issue for hints. The goal is to create a script that programmatically sets CORS headers using the SDK, similar to the manual UI steps described in the AWS docs. Consider implementing this as a reusable module or adding it to an existing deployment script.
