Core Module

Wraps inner business functionality and abstracts certain environment interactions such as opening/closing the database connection and processing the API Gateway input json.

Expected input json:

The following is created by APIGateway along the lines of this definition

{
  "body": {jsonizedPOSTEDObject},
  "params": {
      "querystring": {
          "queryParamifApplicable": "paramValue"
      }
   },
   "context": {
       "sub": "cognitoID"
   }
}

querystring will only have subcomponents if there are query parameters

{jsonizedPOSTEDObject} will be something like:

{
    "var1": 1,
    "var2": "string"
}
