When should I use neon-serverless?

neon-serverless is useful in the following scenarios: • 1. Edge Function Connectivity: Seamlessly connecting Vercel Edge Functions or Cloudflare Workers to Neon PostgreSQL using optimized HTTP drivers to achieve low-latency data access. • 2. Serverless API Development: Configuring AWS Lambda or Google Cloud Functions with proper connection pooling and environment variables for scalable, high-throughput database interactions. • 3. Next.js Project Scaffolding: Rapidly setting up the database access layer in Next.js applications, including the generation of TypeScript boilerplate and secure environment configuration. • 4. Database Performance Tuning: Automatically implementing the correct connection pattern (HTTP Client vs. WebSocket Pool) based on the specific constraints of the deployment environment to minimize cold starts and latency.

from neondatabase-labs

Configures Neon Serverless Driver for Next.js, Vercel Edge Functions, AWS Lambda, and other serverless environments. Installs @neondatabase/serverless, sets up environment variables, and creates working API route examples with TypeScript types. Use when users need to connect their application to Neon, fetch or query data from a Neon database, integrate Neon with Next.js or serverless frameworks, or set up database access in edge/serverless environments where traditional PostgreSQL clients don't work.

When & Why to Use This Skill

This Claude skill automates the setup and configuration of the Neon Serverless Driver for modern web frameworks and serverless platforms like Next.js, Vercel Edge Functions, and AWS Lambda. It streamlines the integration process by installing necessary dependencies, managing environment variables, and generating type-safe API route examples, ensuring high-performance database connectivity in edge and serverless environments where traditional PostgreSQL drivers often struggle.

Use Cases

1. Edge Function Connectivity: Seamlessly connecting Vercel Edge Functions or Cloudflare Workers to Neon PostgreSQL using optimized HTTP drivers to achieve low-latency data access.
2. Serverless API Development: Configuring AWS Lambda or Google Cloud Functions with proper connection pooling and environment variables for scalable, high-throughput database interactions.
3. Next.js Project Scaffolding: Rapidly setting up the database access layer in Next.js applications, including the generation of TypeScript boilerplate and secure environment configuration.
4. Database Performance Tuning: Automatically implementing the correct connection pattern (HTTP Client vs. WebSocket Pool) based on the specific constraints of the deployment environment to minimize cold starts and latency.

Neon Serverless Skill

Configures the Neon Serverless Driver for optimal performance in serverless and edge computing environments.

When to Use

Setting up connections for edge functions (Vercel Edge, Cloudflare Workers)
Configuring serverless APIs (AWS Lambda, Google Cloud Functions)
Optimizing for low-latency database access
Implementing connection pooling for high-throughput apps

Not recommended for: Complex multi-statement transactions (use WebSocket Pool), persistent servers (use native PostgreSQL drivers), or offline-first applications.

Code Generation Rules

When generating TypeScript/JavaScript code:

BEFORE generating import statements, check tsconfig.json for path aliases (compilerOptions.paths)
If path aliases exist (e.g., "@/": ["./src/"]), use them (e.g., import { x } from '@/lib/utils')
If NO path aliases exist or unsure, ALWAYS use relative imports (e.g., import { x } from '../../../lib/utils')
Verify imports match the project's configuration
Default to relative imports - they always work regardless of configuration

Reference Documentation

Primary Resource: See [neon-serverless.mdc](https://raw.githubusercontent.com/neondatabase-labs/ai-rules/main/neon-serverless.mdc) in project root for comprehensive guidelines including:

Quick Setup

Installation

npm install @neondatabase/serverless

Connection Patterns

HTTP Client (recommended for edge/serverless):

import { neon } from '@neondatabase/serverless';
const sql = neon(process.env.DATABASE_URL!);
const rows = await sql`SELECT * FROM users WHERE id = ${userId}`;

WebSocket Pool (for Node.js long-lived connections):

import { Pool } from '@neondatabase/serverless';
const pool = new Pool({ connectionString: process.env.DATABASE_URL! });
const result = await pool.query('SELECT * FROM users WHERE id = $1', [userId]);

See templates/ for complete examples:

templates/http-connection.ts - HTTP client setup
templates/websocket-pool.ts - WebSocket pool configuration

Validation

Use scripts/validate-connection.ts to test your database connection before deployment.

neon-auth - Add authentication
neon-js - Full SDK with auth + data API
neon-drizzle - For ORM with serverless connections
neon-toolkit - For ephemeral database testing
