Prisma Migrations

Modifying schema

Steps

• Modify schema.prisma

• run npm run migrate:dev to create a database migration with the modified schema structure

• run npm run generate to generate the prisma client files to publish

• change the version number in the package.json inside the prisma/guide-client-package (to publish the package).

  • The package will be published (GitHub Actions) when we push to dev and thera are changes in the prisma/guide-client-package directory

• the push to dev will also trigger a GitHub Action to deploy to staging at Fly.io. This will run npx prisma migrate deploy to apply the migration to the "production/staging" database. This command is set up in fly.toml.

• Update version in the package clients. For guide prisma client only in the wandity-remix project for now.

• Prisma has two commands:

  • prisma migrate dev to generate migrations in the development environment
  • prisma migrate deploty to apply migrations to production/staging (in CI/CD) using the DATABASE_URL env variable

Development

• The database url is saved in .env
