Turborepo monorepo with Prisma

​

Overview

These examples demonstrate two different ways of using Prisma and Trigger.dev in a Turborepo monorepo. In both examples, a task is triggered from a Next.js app using a server action, which uses Prisma to add a user to a database table. The examples differ in how Trigger.dev is installed and configured.

• Example 1: Turborepo monorepo demo with Trigger.dev and Prisma packages
• Example 2: Turborepo monorepo demo with a Prisma package and Trigger.dev installed in a Next.js app

​

Example 1: Turborepo monorepo demo with Trigger.dev and Prisma packages

This simple example demonstrates how to use Trigger.dev and Prisma as packages inside a monorepo created with Turborepo. The Trigger.dev task is triggered by a button click in a Next.js app which triggers the task via a server action.

​

Features

• This monorepo has been created using the Turborepo CLI, following the official Prisma and Turborepo docs, and then adapted for use with Trigger.dev.
• pnpm has been used as the package manager.
• A tasks package (@repo/tasks) using Trigger.dev is used to create and execute tasks from an app inside the monorepo.
• A database package (@repo/db) using Prisma ORM is used to interact with the database. You can use any popular Postgres database supported by Prisma, e.g. Supabase, Neon, etc.
• A Next.js example app (apps/web) to show how to trigger the task via a server action.

Relevant files and code

​

Database package

• Prisma is added as a package in /packages/database and exported as @repo/db in the package.json file.
• The schema is defined in the prisma/schema.prisma file.

​

Tasks package

• Trigger.dev is added as a package in /packages/tasks and exported as @repo/tasks in the package.json file.
• The addNewUser.ts task adds a new user to the database.
• The packages/tasks/src/index.ts file exports values and types from the Trigger.dev SDK, and is exported from the package via the package.json file.
• The packages/tasks/src/trigger/index.ts file exports the task from the package. Every task must be exported from the package like this.
• The trigger.config.ts file configures the Trigger.dev project settings. This is where the Trigger.dev Prisma build extension is added, which is required to use Prisma in the Trigger.dev task.

​

The Next.js app apps/web

• The app is a simple Next.js app using the App Router, that uses the @repo/db package to interact with the database and the @repo/tasks package to trigger the task. These are both added as dependencies in the package.json file.
• The task is triggered from a button click in the app in page.tsx, which uses a server action in /app/api/actions.ts to trigger the task with an example payload.
