Prisma + Directus: Version-Controlled Schemas, Seamless Migrations, Reliable Seeds

Seed scripts, schema-as-code, and migrations that just work

Directus excels at turning any SQL database into a headless CMS—but once your project grows, ad-hoc SQL files and one-off dumps become brittle fast. Enter Prisma, a TypeScript ORM that adds order and repeatability to your data layer without getting in Directus's way.

1. The Prisma schema: your single source of truth

model Article {
  id        Int      @id @default(autoincrement())
  title     String
  body      String
  author    User     @relation(fields: [authorId], references: [id])
  authorId  Int
  createdAt DateTime @default(now())
}

Store every table, relationship, index, and enum in one declarative .prisma file.
Commit it to Git—now the database structure is version-controlled alongside your Directus extensions and UI configs.
Introspection (npx prisma db pull) lets you pull existing Directus tables into the schema, so you start with what's already running.

2. Bullet-proof migrations

npx prisma migrate deploy runs the SQL steps generated from your schema differences:

Consistent: The same migration history runs in dev, staging, and prod.
Readable: Prisma generates descriptive SQL files (20250805_add_article_table.sql).
Safe: Preview mode (migrate diff) shows exactly what will change before you hit the database.

Integrate the command into your CI/CD (e.g., a Railway deploy hook) so the schema evolves automatically when you merge to develop.

3. Seeding for predictable test data

Need demo content for a Directus sandbox or Playwright tests? Create a prisma/seed.ts file:

import { PrismaClient } from '@prisma/client'
const prisma = new PrismaClient()

await prisma.user.create({
  data: { name: 'John Doe', email: 'john@example.com' }
})
await prisma.article.create({
  data: { title: 'Hello Directus', body: 'Prisma FTW', authorId: 1 }
})

Run with npx prisma db seed. Because seeds compile with TypeScript, you can:

Pull faker data or CSVs.
Chain API calls to enrich records.
Re-use the same seed script in Cypress e2e runs or Storybook stories.

4. Playing nicely with Directus

Directus's data API and role system remain untouched—Prisma simply handles structural drift.
For custom endpoints/hooks living in directus-extensions/, swap raw SQL for Prisma Client calls; they stay type-safe and auto-update when fields change.
When you add a new table via Prisma and deploy, Directus instantly detects it and exposes it in the Admin UI.

TL;DR

By treating your schema as code, automating migrations, and scripting seeds, Prisma gives Directus projects the same engineering discipline you expect from application code—without sacrificing the low-code flexibility your content team loves.
