Summary by cubic

Makes temporary email generation for anonymous users more flexible and safe. Adds options for local part and domain, and validates generated emails to prevent invalid addresses.

  • New Features

    • Added emailLocalPart and emailDomainName options for temporary emails.
    • Validates generated emails on init; throws a clear BetterAuthError if invalid.
    • Introduced centralized error codes and extracted schema/types/utils.
    • Fixed invalid domain name creation and updated docs.

  • Migration

    • Default behavior changed: if no domain is provided, emails use {localPart}@{id}.com (previously used the site domain). Set emailDomainName (and optionally emailLocalPart) if you rely on a specific domain.
    • Custom email settings must produce a valid address; invalid configs will fail at startup.

Written for commit d2e9b1ac17. Summary will update automatically on new commits.
