Using Regular Expressions and AWS Lambda to Validate API Requests

Regular expressions are often used as a means of validating text fields to ensure the input data matches the desired patterns, such as usernames being of certain character lengths and passwords meeting certain thresholds. In this lab, we will do just that: use AWS Lambda and the API gateway to create a password validator that will use regular expressions and lookarounds to confirm that the password meets our requirements.
