Email — Verification

Email verification extension for Caffeine AI.

Overview

This skill adds email address verification via a click-to-verify link that lands on the app's own frontend. The backend mints and stores the link token (verificationTokens) and confirms it through MixinEmailVerification; verifiedEmails tracks verified addresses. The frontend renders the /verify-email page, where the recipient clicks a button to confirm.

Required Setup Checklist

All five steps are mandatory.

1. mops dependencies — mops add caffeineai-email-verification and mops add caffeineai-email.
2. Two stable state fields — verifiedEmails : VerifiedEmails.State and verificationTokens : VerificationTokens.State, initialised in the migration chain head with VerifiedEmails.new() and VerificationTokens.new().
3. Mixin invocation — include MixinEmailVerification(verifiedEmails, verificationTokens) in main.mo.
4. Sending — EmailVerification.sendVerificationEmail(verificationTokens, fromUsername, recipients, subject, htmlBody); the body MUST contain {{VERIFICATION_URL}}.
5. Frontend npm package and route — @caffeineai/email-verification installed, and a public route /verify-email (reachable without signing in) that renders a button calling confirm().

CRITICAL: the link in the email is https://<app domain>/verify-email?token=…. Without the frontend route the recipient lands on a missing page and the address is never verified.
