Template design goal

• exclude aws-sdk and other unused packages from the zipped deployment bundle
• use typescript to leverage static typing, interface, autocompletion, aws-lambda definition
• automate deployment. Make changes and just run npm run deploy

Exclude aws-sdk from the zipped deployment bundle

aws-sdk is already pre-installed in lambda environment. For that reason we do not have to and we do not want to bundle aws-sdk into the deployment zip file. We use lambpack to help with that.

The pre-configured node_module/aws-sdk in package.json is of version 2.249.1. Which is the same version as what is is installed in the aws lambda container (according to https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html).
