v1.2.0 — Cloud Database, Production Auth & SEO ☁️

☁️ Conn v1.2.0 — Cloud Database, Production Auth & SEO

Production-ready deployment: migrated from local JSON files to Supabase PostgreSQL, replaced in-memory sessions with JWT cookies, and added comprehensive SEO.

🔧 Backend Migration (Fixes Vercel Deployment)

Problem: The app was broken on Vercel because:

• Vercel has a read-only filesystem — fs.writeFileSync() crashed on every signup/login
• express-session used in-memory storage which is lost between serverless requests
• Data files (data/*.json) were gitignored and didn't exist on the server

Solution:

• Migrated all data storage to Supabase PostgreSQL (cloud database)
• Replaced express-session + MemoryStore with JWT tokens in httpOnly cookies (stateless, works on any serverless platform)
• Added vercel.json to correctly route all traffic through Express

Database Tables (6 total)

• users — accounts, credentials, subscription plan
• user_profiles — name, bio, avatar, social links
• user_links — all links with click tracking
• user_settings — theme, SEO, branding preferences
• contacts — contact form submissions
• orders — Razorpay payment orders

New Files

• db.js — Supabase client singleton (service_role key)
• vercel.json — Vercel serverless routing config
• scripts/setup-db.sql — One-click SQL to create all tables in Supabase
• scripts/seed-db.js — Migrate local JSON data to Supabase (npm run seed)

🔐 Auth Improvements

• JWT tokens in secure httpOnly cookies (7-day expiry)
• Works across serverless function instances (stateless)
• Proper secure and sameSite: lax cookie flags for production HTTPS

🔍 SEO Improvements

• robots.txt — instructs crawlers what to index/block
• sitemap.xml — all public pages for faster Google discovery
• JSON-LD SoftwareApplication schema on homepage (rich results with pricing)
• JSON-LD Person schema dynamically injected per user's public profile page
• Dynamic page title, description, Open Graph, and Twitter meta tags per /u/:username profile
• Canonical URLs, og:image dimensions, og:site_name, twitter:site tags
• preconnect + dns-prefetch hints for faster page loads (Core Web Vitals)

📦 Dependencies

Added: @supabase/supabase-js, jsonwebtoken, cookie-parser
Removed: express-session (no longer needed)
