Greg aa0d14b679 Add favorites/library app with Coolify deployment setup 
Personal favorites tracker: Next.js 16 App Router, Prisma/PostgreSQL,
NextAuth v5 credentials auth with admin/friend roles, category-driven
custom fields, lending library, optional S3 cover images.

Deployment: multi-stage Dockerfile (standalone output) whose entrypoint
runs prisma migrate deploy and the idempotent seed on every boot; env
validation made lazy so next build works in the secret-free image.
See DEPLOY.md for Coolify setup.

Deploying on Coolify

The repo ships a multi-stage Dockerfile. On every container start, docker-entrypoint.sh applies pending Prisma migrations, runs the idempotent seed (default categories + admin bootstrap), then starts the standalone Next.js server on port 3000.

One-time setup

  1. Database — in Coolify, create a PostgreSQL resource. Copy its internal connection URL (the app and DB talk over Coolify's internal network).

  2. Application — create an application from this git repository.

    • Build pack: Dockerfile
    • Port: 3000

  3. Environment variables (set in Coolify, mark secrets as such):

    Variable Value
    DATABASE_URL internal Postgres URL from step 1
    AUTH_SECRET generate with openssl rand -base64 32
    AUTH_TRUST_HOST true (required behind Coolify's reverse proxy)
    ADMIN_EMAIL login email for the first admin user
    ADMIN_PASSWORD initial admin password (change after first login)

    Optional: the S3_* variables enable cover-image uploads (any S3-compatible store, e.g. Cloudflare R2 or a Coolify-hosted MinIO); TMDB_API_KEY, GOOGLE_BOOKS_API_KEY, SPOTIFY_CLIENT_ID/SECRET, GOOGLE_PLACES_API_KEY, YELP_API_KEY enable metadata lookups. NEXTAUTH_URL is not needed — AUTH_TRUST_HOST=true derives the URL from the request.

  4. Domain — assign your domain/HTTPS in Coolify and deploy.

The admin user is only created if no admin exists yet, and the seed never overwrites categories you've edited, so redeploys are safe.

Health check (optional)

Unauthenticated requests to / redirect to /login, so point Coolify's health check at /login (expects HTTP 200).
