To implement the Go function for user registration, create a server-side code that

• handles incoming registration requests,
• validates the user input,
• checks for duplicate emails,
• encrypts the password,
• inserts the user data into the SQLite database, and
• returns appropriate responses to the client..

A possible application file structure:
