Generate and instantiate Prisma ORM 7 Client for SQL providers. For MongoDB, follow Prisma 6 MongoDB setup. For an existing Prisma 6 SQL app, preserve its client setup rather than copying these examples.
npm install --save-dev prisma@7
npm install @prisma/client@7 dotenvFor an existing application, retain its pinned releases. For a new Prisma 7 application, use compatible CLI, client, and adapter versions and check the Prisma 7 runtime requirements (opens in a new tab).
In prisma/schema.prisma:
generator client {
provider = "prisma-client"
output = "../generated"
}prisma-client requires an explicit output path and does not generate into node_modules by default.
npx prisma generateRe-run prisma generate after every schema change to keep the client in sync.
import 'dotenv/config'
import { PrismaClient } from '../generated/client'
import { PrismaPg } from '@prisma/adapter-pg'
const adapter = new PrismaPg({ connectionString: process.env.DATABASE_URL })
const prisma = new PrismaClient({ adapter })If you change the generator output, update the import path to match. For the SQL provider workflow, replace PrismaPg with the adapter for your database.
Each PrismaClient instance creates a connection pool. Reuse a single instance per app process to avoid exhausting database connections.
