generateLambdaDispatcher :: DecsQ Source #

Generates a main function that acts as a dispatcher

decodeObj :: FromJSON a => String -> a Source #

Helper function that the dispatcher will use to decode the JSON that comes as an AWS Lambda event into the appropriate type expected by the handler.

encodeObj :: ToJSON a => a -> String Source #

Helper function that the dispatcher will use to decode the JSON that comes as an AWS Lambda event into the appropriate type expected by the handler.
