Prisma setup guide

The easiest way to get started is to use the CLI. It will add Trigger.dev to your existing project, create a /trigger folder and give you an example task.

Run this command in the root of your project to get started:

It will do a few things:

1. Log you into the CLI if you’re not already logged in.
2. Create a trigger.config.ts file in the root of your project.
3. Ask where you’d like to create the /trigger directory.
4. Create the /trigger directory with an example task, /trigger/example.[ts/js].

Install the “Hello World” example task when prompted. We’ll use this task to test the setup.

The CLI dev command runs a server for your tasks. It watches for changes in your /trigger directory and communicates with the Trigger.dev platform to register your tasks, perform runs, and send data back and forth.

It can also update your @trigger.dev/* packages to prevent version mismatches and failed deploys. You will always be prompted first.

The CLI dev command spits out various useful URLs. Right now we want to visit the Test page

You should see our Example task in the list

Press the “Run test” button

Congratulations, you should see the run page which will live reload showing you the current state of the run.

If you go back to your terminal you’ll see that the dev command also shows the task status and links to the run log.

First, create a new task file in your trigger folder.

This is a simple task that will add a new user to the database.

import { PrismaClient } from "@prisma/client";
import { task } from "@trigger.dev/sdk/v3";

// Initialize Prisma client
const prisma = new PrismaClient();

export const addNewUser = task({
  id: "prisma-add-new-user",
  run: async (payload: { name: string; email: string; id: number }) => {
    const { name, email, id } = payload;

    // This will create a new user in the database
    const user = await prisma.user.create({
      data: {
        name: name,
        email: email,
        id: id,
      },
    });

    return {
      message: `New user added successfully: ${user.id}`,
    };
  },
});

Next, configure the Prisma build extension in the trigger.config.js file to include the Prisma client in the build.

This will ensure that the Prisma client is available when the task runs.

For a full list of options available in the Prisma build extension, see the Prisma build extension documentation.

export default defineConfig({
  project: "<project ref>", // Your project reference
  // Your other config settings...
  build: {
    extensions: [
      prismaExtension({
        version: "5.20.0", // optional, we'll automatically detect the version if not provided
        // update this to the path of your Prisma schema file
        schema: "prisma/schema.prisma",
      }),
    ],
  },
});

We use OpenTelemetry to instrument our tasks and collect telemetry data.

If you want to automatically log all Prisma queries and mutations, you can use the Prisma instrumentation extension.

import { defineConfig } from "@trigger.dev/sdk/v3";
import { PrismaInstrumentation } from "@prisma/instrumentation";
import { OpenAIInstrumentation } from "@traceloop/instrumentation-openai";

export default defineConfig({
  //..other stuff
  instrumentations: [new PrismaInstrumentation(), new OpenAIInstrumentation()],
});

This provides much more detailed information about your tasks with minimal effort.

With the build extension and task configured, you can now deploy your task using the Trigger.dev CLI.

In your Trigger.dev dashboard sidebar click “Environment Variables”

You can add values for your local dev environment, staging and prod. in this case we will add the DATABASE_URL for the production environment.

To test this task, go to the ‘test’ page in the Trigger.dev dashboard and run the task with the following payload:

{
  "name": "<a-name>", // e.g. "John Doe"
  "email": "<a-email>", // e.g. "[email protected]"
  "id": <a-number> // e.g. 12345
}

Congratulations! You should now see a new completed run, and a new user with the credentials you provided should be added to your database.
