Neon Postgres

Expert patterns for Neon serverless Postgres, branching, connection pooling, and Prisma/Drizzle integration

Patterns

Prisma with Neon Connection

Configure Prisma for Neon with connection pooling.

Use two connection strings:

• DATABASE_URL: Pooled connection for Prisma Client
• DIRECT_URL: Direct connection for Prisma Migrate

The pooled connection uses PgBouncer for up to 10K connections. Direct connection required for migrations (DDL operations).

Code_example

.env

Pooled connection for application queries

DATABASE_URL="postgres://user:[e-mail]/neondb?sslmode=require"

Direct connection for migrations

DIRECT_URL="postgres://user:[e-mail]/neondb?sslmode=require"

// prisma/schema.prisma generator client { provider = "prisma-client-js" }

datasource db { provider = "postgresql" url = env("DATABASE_URL") directUrl = env("DIRECT_URL") }

model User { id String @id @default(cuid()) email String @unique name String? createdAt DateTime @default(now()) updatedAt DateTime @updatedAt }

// lib/prisma.ts import { PrismaClient } from '@prisma/client';

const globalForPrisma = globalThis as unknown as { prisma: PrismaClient | undefined; };

export const prisma = globalForPrisma.prisma ?? new PrismaClient({ log: process.env.NODE_ENV === 'development' ? ['query', 'error', 'warn'] : ['error'], });

if (process.env.NODE_ENV !== 'production') { globalForPrisma.prisma = prisma; }

// Run migrations // Uses DIRECT_URL automatically npx prisma migrate dev npx prisma migrate deploy

Anti_patterns

• Pattern: Using pooled connection for migrations | Why: DDL operations fail through PgBouncer | Fix: Set directUrl in schema.prisma
• Pattern: Not using connection pooling | Why: Serverless functions exhaust connection limits | Fix: Use -pooler endpoint in DATABASE_URL

Drizzle with Neon Serverless Driver

Use Drizzle ORM with Neon's serverless HTTP driver for edge/serverless environments.

Two driver options:

• neon-http: Single queries over HTTP (fastest for one-off queries)
