Prisma Migrations

Rollback and programmatic migrations for Prisma

Adds up/down migrations, rollback, and programmatic API to Prisma. Compatible with Prisma 5, 6, and 7.

Feature	Prisma Migrate	This Tool
Run migrations forward	Yes	Yes
Rollback migrations	No	Yes
Run from Node.js code	No	Yes
Step-by-step control	No	Yes

Uses Prisma's _prisma_migrations table. Works alongside prisma migrate.

Installation

npm install prisma-migrations @prisma/client prisma

Quick Start

# Create a migration
npx prisma-migrations create add_users_table

# Run it
npx prisma-migrations up

# Roll back
npx prisma-migrations down

Migration file (prisma/migrations/[timestamp]_add_users_table/migration.sql):

-- Migration: Up
CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email VARCHAR(255) UNIQUE NOT NULL
);

-- Migration: Down
DROP TABLE IF EXISTS users;

CLI

npx prisma-migrations up              # Run all pending
npx prisma-migrations up --steps 2    # Run next 2
npx prisma-migrations down            # Rollback last
npx prisma-migrations down --steps 3  # Rollback last 3
npx prisma-migrations status          # Check status
npx prisma-migrations reset --force   # Rollback all

Programmatic API

import { Migrations } from 'prisma-migrations';
import { PrismaClient } from '@prisma/client';

const prisma = new PrismaClient();
const migrations = new Migrations(prisma);

await migrations.up();       // Run all pending
await migrations.down();     // Rollback last
await migrations.pending();  // Get pending list

await prisma.$disconnect();

Production Safety

• Transactions: Migrations run in database transactions with automatic rollback on failure
• Lock Protection: Advisory locks prevent concurrent migration runs
• Checksum Validation: Detects if applied migrations have been modified

For concurrent deployments:

const result = await migrations.upIfNotLocked();
if (result.ran) {
  console.log(`Applied ${result.count} migrations`);
}
