# Turborepo monorepo with Prisma
> Two example projects demonstrating how to use Prisma and Trigger.dev in a Turborepo monorepo setup.
## 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
You can either fork the repos below, or simply check out the project structures and code to get an idea of how to set up Trigger.dev in your own monorepos.
## 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.
### GitHub repo

Click here to view the full code for this project in our examples repository on GitHub. You can
fork it and use it as a starting point for your own project.
### Features
* This monorepo has been created using the [Turborepo CLI](https://turbo.build/repo), following the official [Prisma and Turborepo docs](https://www.prisma.io/docs/guides/turborepo), and then adapted for use with Trigger.dev.
* [pnpm](https://pnpm.io/) has been used as the package manager.
* A tasks package (`@repo/tasks`) using [Trigger.dev](https://trigger.dev) is used to create and execute tasks from an app inside the monorepo.
* A database package (`@repo/db`) using [Prisma ORM](https://www.prisma.io/docs/orm/) is used to interact with the database. You can use any popular Postgres database supported by Prisma, e.g. [Supabase](https://supabase.com/), [Neon](https://neon.tech/), etc.
* A [Next.js](https://nextjs.org/) 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`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/database/) and exported as `@repo/db` in the [`package.json`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/database/package.json) file.
* The schema is defined in the [`prisma/schema.prisma`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/database/prisma/schema.prisma) file.
#### Tasks package
to run `pnpm dlx trigger.dev@latest init` in a blank packages folder, you have to add a `package.json` file first, otherwise it will attempt to add Trigger.dev files in the root of your monorepo.
* Trigger.dev is added as a package in [`/packages/tasks`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/tasks) and exported as `@repo/tasks` in the [`package.json`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/tasks/package.json) file.
* The [`addNewUser.ts`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/tasks/src/trigger/addNewUser.ts) task adds a new user to the database.
* The [`packages/tasks/src/index.ts`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/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`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/tasks/package.json) file.
* The [`packages/tasks/src/trigger/index.ts`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/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`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/packages/tasks/trigger.config.ts) file configures the Trigger.dev project settings. This is where the Trigger.dev [Prisma build extension](https://trigger.dev/docs/config/extensions/prismaExtension) is added, which is required to use Prisma in the Trigger.dev task.
You must include the version of Prisma you are using in the `trigger.config.ts` file, otherwise the Prisma build extension will not work. Learn more about our [Prisma build extension](/config/extensions/prismaExtension).
#### 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`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/apps/web/package.json) file.
* The task is triggered from a button click in the app in [`page.tsx`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/apps/web/app/page.tsx), which uses a server action in [`/app/api/actions.ts`](https://github.com/triggerdotdev/examples/tree/main/monorepos/turborepo-prisma-tasks-package/apps/web/app/api/actions.ts) to trigger the task with an example payload.

## Example 2: Turborepo monorepo demo with a Prisma package and Trigger.dev installed in a Next.js app
This example demonstrates how to use Trigger.dev and Prisma in a monorepo created with Turborepo. Prisma has been added as a package, and Trigger.dev has been installed in a Next.js app. The task is triggered by a button click in the app via a server action.
