NextJS API for Custom Signup

The code above defines a function handler that takes two arguments, req and res. req is a NextApiRequest object, which represents a request to the server. res is a NextApiResponse object, which represents the response from the server. data is an undefined variable that will be filled with the data from the request. validUser is a boolean variable that will determine whether or not the user exists. If validUser is true, then the business logic for createUser() will execute and return a 200 status code. If validUser is false, then the business logic for createUser() will return a 400 status code with the error message Element Exists.
