This pull request introduces improvements to the customer creation API and the customer lookup logic, focusing on better input validation and more robust email handling.
Input validation:
emailfield is a string in thePOSThandler ofapp/api/createCustomer/route.tsx, returning a clear error if not.Email normalization and lookup:
getCustomerByEmailfunction inlib/db.tsto normalize the email by trimming whitespace and converting to lowercase before querying. If no match is found and the normalized email differs from the original, a second query is performed using the original email value. This improves reliability for customer lookups regardless of input formatting.Related Issues:
