Summary : Email delivery system integration (Contact Form + OTP), Railway deployment debugging, and infrastructure troubleshooting.

What’s Complete

1. Email Service Architecture (Priority-Based Fallback)Status: Fully Integrated & Production-Ready

Contact Form Email Flow

• File: src/routes/contact.js
• Priority 1 (Production): Resend API — works on Railway, no outbound restrictions
• Priority 2 (Local Dev): Nodemailer + Gmail SMTP (port 587, TLS)
• Format: Visitor name in sender, reply-to set to visitor email for direct Gmail replies
• Testing: Verified via curl — email successfully delivered to [email protected]

OTP Email Flow

• File: src/routes/auth.js
• Priority 1 (Production): Resend API — handles 6-digit OTP codes
• Priority 2 (Local Dev): Nodemailer + Gmail SMTP
• Timeout: 5-minute code expiration
• Verified: Code generation and storage logic working correctly

2. Frontend Contact Form Fix

Status: Resolved Event Binding Issue

• Problem: DOMContentLoaded event wrapper in contact.js was unreliable because script loads after DOM already ready
• Solution: Removed wrapper, direct event attachment at script execution- Added: Console debug logging for form submission tracking and error diagnosis
• Result: Form submission now reliably attaches event listeners and sends fetch requests

3. Railway Deployment Testing*

Status: Contact form working in production

• Domain: https://duskcoffee-production.up.railway.app
• Tested by: User (Kaedara) — successfully sent contact message
• Response logs show: Payload received, message queued, response returned to frontend
• Email delivery: Via Resend (Nodemailer fallback blocked due to Railway SMTP restrictions)
