Neon Postgres

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).

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)
neon-serverless: WebSocket for transactions and sessions

Connection Pooling with PgBouncer

Neon provides built-in connection pooling via PgBouncer.

Key limits:

Up to 10,000 concurrent connections to pooler
Connections still consume underlying Postgres connections
7 connections reserved for Neon superuser

Use pooled endpoint for application, direct for migrations.
