Neon Auth for React

Help developers set up @neondatabase/auth (authentication only, no database) in React applications with Vite, Create React App, or similar bundlers.

When to Use

Use this skill when:

• Setting up auth-only in React (no database needed)
• User already has a database solution
• User mentions "@neondatabase/auth" without "neon-js"
• User is NOT using Next.js (use neon-auth-nextjs skill for Next.js)

Critical Rules

1. Adapter Factory Pattern: Always call adapters with () - they are factory functions
2. React Adapter Import: Use subpath @neondatabase/auth/react/adapters
3. createAuthClient takes URL as first arg: createAuthClient(url, config)
4. CSS Import: Choose ONE - either /ui/css OR /ui/tailwind, never both
