Prisma Config

In Prisma ORM v7+, configuration moves beyond the package.json or schema.prisma limits. The prisma.config.ts file serves as the central, type-safe hub for your ORM setup.

The Configuration File

Create a file named prisma.config.ts in your project root. This file exports your configuration object using the defineConfig helper.

import { defineConfig, env } from "prisma/config";
import "dotenv/config";

export default defineConfig({
  // Location of your Prisma Schema
  schema: "prisma/schema.prisma",

  // Migrations & Seeding configuration
  migrations: {
    path: "prisma/migrations",
    seed: "tsx prisma/seed.ts",
  },

  // Database Connection
  datasource: {
    url: env("DATABASE_URL"),
  },
});

Configuration Options

Property	Type	Description
schema	string	The relative path to your `schema.prisma` file.
migrations.path	string	The directory where migration history and SQL files will be stored.
migrations.seed	string	The terminal command to run your seed script (e.g., using `tsx` or `node`).
datasource.url	string	The connection string for your database. Use the `env()` helper to load this securely from environment variables.

Managing Environment Variables

Prisma v7 removes the automatic loading of .env files. You must explicitly import a loader like dotenv at the top of your config file.

import "dotenv/config";
