# Optional defaults for in-memory API rate limiting
RATE_LIMIT_WINDOW_MS=60000
RATE_LIMIT_MAX=120

# Optional dedicated Postgres URL for shortener.
# If omitted, shortener falls back to SUPABASE_DB_URL, POSTGRES_URL or DATABASE_URL.
# SHORTENER_DATABASE_URL=postgresql://user:pass@host:5432/tools4dev?sslmode=require

# Optional Supabase Postgres URL shortcut (used when SHORTENER_DATABASE_URL is empty)

# Optional: enable Supabase HTTP mode for shortener (avoids direct Postgres connection)
# SHORTENER_USE_SUPABASE_HTTP=true
# SUPABASE_URL=https://<project-ref>.supabase.co
# SUPABASE_SERVICE_ROLE_KEY=your-service-role-key

# Vercel + Supabase integration usually exposes:
# POSTGRES_URL=postgresql://...
# POSTGRES_PRISMA_URL=postgresql://...
# POSTGRES_URL_NON_POOLING=postgresql://...
# If URL vars are absent, shortener also mounts from:
# POSTGRES_USER + POSTGRES_HOST + POSTGRES_DATABASE + POSTGRES_PASSWORD
# (optional: POSTGRES_PORT)

# Optional table name for shortener links
# Supports table or schema.table (ex.: public.short_links)
