Platformatic Prisma

npm version

Remove the friction to create migrations for your Platformatic DB by generating them using a Prisma schema.

  • Use Prisma schema to manage your data models
  • Generate Platformatic DB compatible up and down migrations when changes are made to your Prisma schema
  • Migrations will be run by Platformatic DB

View the example project to see it in action.

Getting Started

Install platformatic-prisma and prisma:

npm install prisma platformatic-prisma -D

Create a ./prisma/schema.prisma file with the following contents:

datasource db {
  // Any provider supported by Platformatic
  // https://oss.platformatic.dev/docs/reference/db/introduction#supported-databases
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

// Table used by Platformatic/Postgrator to manage migrations
model Version {
  version BigInt    @id
  name    String?
  md5     String?
  run_at  DateTime? @db.Timestamptz(6)

  @@map("versions")
  @@ignore
}

Create an .env file containing the database connection URL to connect to your database:

DATABASE_URL="postgresql://postgres:@localhost:5432/platformatic-prisma?schema=public"

Generating Migrations

Note If you are just starting with a new Platformatic DB project, run npx platformatic db migrate before generating your first migration. This is needed to allow Platformatic DB to initialize the database with it's migrations table.

When changes are made to your schema.prisma file, run npx platformatic-prisma to generate migrations. This will generate up and down migration files in the migrations directory that is specified in your Platformatic configuration file.

To run migrations, refer to Platformatic's documentation.
