prismaExtension

Use Prisma with Trigger.dev. Three modes depending on your Prisma version and needs.

Setup

import { prismaExtension } from "@trigger.dev/build/extensions/prisma";

export default defineConfig({
  project: "<project ref>",
  build: {
    extensions: [
      prismaExtension({
        version: "5.19.0",   // your prisma version
        provider: "postgresql",
        schema: "./prisma/schema.prisma", // default: auto-detected
      }),
    ],
  },
});

Three Modes

legacy (Prisma < 5.2.0)

prismaExtension({
  version: "4.x.x",
  provider: "postgresql",
  mode: "legacy",
})

Downloads full Prisma binary for schema.prisma. Used for older Prisma versions.

engine-only (Prisma 5.2.0 – 6.x, default)

prismaExtension({
  version: "5.19.0",
  provider: "postgresql",
  mode: "engine-only", // can be omitted — this is the default
})

Downloads only the query engine. More efficient than legacy mode.

modern (Prisma 6.6.0+, recommended for new projects)

prismaExtension({
  version: "6.6.0",
  provider: "postgresql",
  mode: "modern",
})

No engine files downloaded — uses Prisma's new architecture. Requires Prisma 6.6.0+.

Mode is required in Prisma 4.1.1+

Starting with @trigger.dev/build 4.1.1, mode defaults to engine-only if not specified. Set explicitly for clarity.

Version Compatibility

Prisma Version	Recommended Mode
< 5.2.0	legacy
5.2.0 – 6.5.x	engine-only
6.6.0+	modern

Binary Targets

prismaExtension({
  version: "5.19.0",
  provider: "postgresql",
  binaryTargets: ["debian-openssl-3.0.x"],
})

Environment Variables

The extension auto-sets these based on your schema:

• DATABASE_URL — primary database connection

Multiple Schema Files

prismaExtension({
  version: "5.19.0",
  provider: "postgresql",
  schema: "./prisma/schema.prisma",
})

For multiple schemas, add multiple extension entries.
