Prisma driver adapter for Neon serverless driver

Prisma driver adapter for Neon Serverless Driver. Refer to the announcement blog post and our docs for more details.

Note:: Support for Neon's serverless driver is available from Prisma versions 5.4.2 and later.

The Neon serverless driver is a low-latency Postgres driver for JavaScript and TypeScript that allows you to query data from serverless and edge environments.

Getting started

Note: Make sure your connection string exists in your process.env. Refer to Neon's docs to learn how to retrieve your database's connection string.
bash
DATABASE_URL="postgres://user:[email protected]/neondb"

To get started, install the Prisma adapter for Neon's serverless driver and ws packages:

npm install @prisma/adapter-neon
npm install ws

Update your Prisma Client instance to use the Neon serverless driver using a WebSocket connection:

// Import needed packages
import { neonConfig } from '@neondatabase/serverless'
import { PrismaNeon } from '@prisma/adapter-neon'
import { PrismaClient } from '@prisma/client'
import ws from 'ws'

// Setup
neonConfig.webSocketConstructor = ws
const connectionString = `${process.env.DATABASE_URL}`

// Init prisma client
const adapter = new PrismaNeon({ connectionString })
const prisma = new PrismaClient({ adapter })

// Use Prisma Client as normal

You can now use Prisma Client as you normally would with full type-safety. Your Prisma Client instance now uses Neon's serverless driver to connect to your database. This comes with benefits such as WebSocket connections and message pipelining.
