Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/neondatabase/ai-rules --skill neon-js- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads neon-js automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Neon JS SDK Integration
Set up the unified Neon JS SDK for authentication and database queries in one package.
When to Use This Skill
- Building apps that need both auth and database queries
- Migrating from Supabase to Neon
- Using PostgREST-style API for database access
- Need type-safe database queries with generated types
Package: @neondatabase/neon-js (full SDK with auth + data API)
Need auth only? Use the neon-auth skill instead for @neondatabase/auth with a smaller bundle.
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.jsonfor path aliases before generating imports - Use relative imports if unsure or no aliases exist
BetterAuthReactAdapterMUST be imported fromauth/react/adapterssubpath- Adapters are factory functions - call them with
() - Choose ONE CSS import method (Tailwind or CSS, not both)
