neon-auth（霓虹灯认证）

Neon Auth Integration

Add authentication to your application.

When to Use This Skill

• Adding authentication to a new or existing project
• Implementing sign-in, sign-up, and session management
• Configuring social authentication (Google, GitHub)

Package: @neondatabase/auth (auth only, smaller bundle)

Need database queries too? Use the neon-js skill instead for @neondatabase/neon-js with unified auth + data API.

Code Generation Rules

When generating TypeScript/JavaScript code, follow these rules:

Complete reference: See Code Generation Rules for:

• Import path handling (path aliases vs relative imports)
• Neon package imports (subpath exports, adapter patterns)
• CSS import strategy (Tailwind detection, single import method)
• File structure patterns

Key points:

• Check tsconfig.json for path aliases before generating imports
• Use relative imports if unsure or no aliases exist
• BetterAuthReactAdapter MUST be imported from auth/react/adapters subpath
• Adapters are factory functions - call them with ()
• Choose ONE CSS import method (Tailwind or CSS, not both)

Available Guides

Each guide is a complete, self-contained walkthrough with numbered phases:

• guides/nextjs-setup.md - Complete Next.js App Router setup guide
• guides/react-spa-setup.md - Detailed React SPA guide with react-router-dom integration

I'll automatically detect your context (package manager, framework, existing setup) and select the appropriate guide based on your request.

For troubleshooting, see the Troubleshooting Guide in references.

Quick Examples

Tell me what you're building - I'll handle the rest:

• "Add authentication to my Next.js app" -> Loads setup guide, sets up auth routes
• "Set up sign-in with Google" -> Configures social auth provider
• "Debug my auth session not persisting" -> Loads troubleshooting guide

Workflow

I will:

1. Detect your project context automatically (Next.js, React SPA, Node.js)
2. Select and load the appropriate guide
3. Follow the guide's phases sequentially
4. Track progress using the guide's workflow checklist
5. Load reference files only when needed
6. Offer to add Neon best practices to your project docs
