Email validation is still primitive but checks if the email could theoretically exist (name@domain.com). Separation of Subscriber type into a module as well as actions that cane be performed on it. Updates to the subscribe functionality to align with new test cases that have been made.
Logs in much greater detail using the tracing packages and formatted using Bunyan. Advised to install bunyan on machine for more pretty logs over raw json.
Also updated tests to reflect the new PgPool format being used. Tests now create a mock database on creation to determine if it works before removing it. Up to Chapter 4.
