Local development with SAM

This method allows you to iterate very quickly against Lambda code without having to run AWS resources locally.

Requirements

• AWS CLI
• SAM CLI

Step 1: Create and deploy a simple SAM Template (see template.yaml)

• must include the environment varibales on the Lambda to pass the SAMPLE_TABLE in (see line 17)
• use sam deploy --guided for the first time deploy

## Manage your Lambda layer in SAM
## This creates a layer and the permissions for the layer. This particular permission opens it to the world.
## I then use 'sam package' and 'sam deploy' to create/update the layer
