• Node.js 20+
• pnpm 9.1.1+
• Cloudflare account (for deployment)

# Install dependencies
pnpm install

# Run development servers
pnpm dev

# Deploy to production
pnpm deploy

Backend requires:

• OPENAI_API_KEY - For CTA extraction (optional, falls back to NONE)
• DB - D1 database binding
• EMAIL_QUEUE - Queue binding
• RealtimeEmails - Durable Object binding

The application uses Cloudflare D1 (SQLite) with the following schema:

CREATE TABLE email (
  id INTEGER PRIMARY KEY,
  to TEXT NOT NULL,
  from TEXT NOT NULL,
  subject TEXT,
  body TEXT NOT NULL,
  createdAt TEXT NOT NULL,
  ctaType TEXT NOT NULL, -- 'NONE' | 'CODE' | 'LINK'
  ctaContent TEXT
);

Indexes on to and createdAt for efficient querying.

• POST /test/:email - Send test email to specified address
• GET /email/:slug - Get all emails for a slug

• @nivekithan - Backend & Infrastructure
• @Aayushman - Frontend Development

Note: This is a testing tool. Do not use for sensitive or production email communications.
