Prisma Client Setup

Generate and instantiate Prisma Client for any database provider.

1. Install dependencies

npm install prisma --save-dev
npm install @prisma/client

2. Add generator block

In prisma/schema.prisma:

generator client {
  provider = "prisma-client"

Prisma v7 requires an explicit output path and will not generate into node_modules by default.

3. Generate Prisma Client

Re-run prisma generate after every schema change to keep the client in sync.

4. Instantiate Prisma Client

If you change the generator output, update the import path to match. In Prisma ORM 7, a driver adapter is required — replace PrismaPg with the adapter for your database.

5. Use a single instance

Each PrismaClient instance creates a connection pool. Reuse a single instance per app process to avoid exhausting database connections.
