wire-auth

Set up auth end-to-end — provider, database sync, row-level security, frontend hooks, and session management. RLS and race conditions are in here, not left as an exercise.

Phase 1: Detect the Stack

Before writing anything, figure out what exists.

1.1 Auth Provider

Check for existing auth:

• @clerk/nextjs in package.json → Clerk
• next-auth in package.json → NextAuth.js
• @supabase/auth-helpers-nextjs or @supabase/ssr → Supabase Auth
• firebase/auth → Firebase Auth
• None → ask the user which to set up

1.2 Database

• @supabase/supabase-js → Supabase (Postgres)
• @prisma/client → Prisma (check schema.prisma for provider)
• drizzle-orm → Drizzle
• mongoose → MongoDB
