This example shows how to implement a fullstack app using Next.js 15 with App Router, Prisma ORM and a Prisma Postgres database.

Download this example:

npx try-prisma@latest --template orm/nextjs --install npm --name nextjs

Then, navigate into the project directory:

cd nextjs

git clone git@github.com:prisma/prisma-examples.git --depth=1

cd prisma-examples/orm/nextjs
npm install

Create a new Prisma Postgres database by executing:

npx prisma init --db

If you don't have a Prisma Data Platform account yet, or if you are not logged in, the command will prompt you to log in using one of the available authentication providers. A browser window will open so you can log in or create an account. Return to the CLI after you have completed this step.

Once logged in (or if you were already logged in), the CLI will prompt you to:

1. Select a region (e.g. us-east-1)
2. Enter a project name

After successful creation, you will see output similar to the following:

Let's set up your Prisma Postgres database!
? Select your region: ap-northeast-1 - Asia Pacific (Tokyo)
? Enter a project name: testing-migration
✔ Success! Your Prisma Postgres database is ready ✅

We found an existing schema.prisma file in your current project directory.

--- Database URL ---

Connect Prisma ORM to your Prisma Postgres database with this URL:

prisma+postgres://accelerate.prisma-data.net/?api_key=...

--- Next steps ---

Go to https://pris.ly/ppg-init for detailed instructions.

1. Install and use the Prisma Accelerate extension
Prisma Postgres requires the Prisma Accelerate extension for querying. If you haven't already installed it, install it in your project:
npm install @prisma/extension-accelerate

...and add it to your Prisma Client instance:
import { withAccelerate } from "@prisma/extension-accelerate"

const prisma = new PrismaClient().$extends(withAccelerate())

2. Apply migrations
Run the following command to create and apply a migration:
npx prisma migrate dev

3. Manage your data
View and edit your data locally by running this command:
npx prisma studio

...or online in Console:
https://console.prisma.io/{workspaceId}/{projectId}/studio

4. Send queries from your app
If you already have an existing app with Prisma ORM, you can now run it and it will send queries against your newly created Prisma Postgres instance.

5. Learn more
For more info, visit the Prisma Postgres docs: https://pris.ly/ppg-docs

Locate and copy the database URL provided in the CLI output. Then, create a .env file in the project root:

touch .env

Now, paste the URL into it as a value for the DATABASE_URL environment variable. For example:

# .env
DATABASE_URL=prisma+postgres://accelerate.prisma-data.net/?api_key=ey...

Run the following command to create tables in your database. This creates the User and Post tables that are defined in prisma/schema.prisma:

npx prisma migrate dev --name init

Execute the seed file in prisma/seed.ts to populate your database with some sample data, by running:

npx prisma db seed

npm run dev

The server is now running on http://localhost:3000. You can now view all different pages:

• Home: http://localhost:3000/
• All posts: http://localhost:3000/posts
• New post: http://localhost:3000/posts/new
• Post details: http://localhost:3000/posts/1

Evolving the application typically requires two steps:

1. Migrate your database using Prisma Migrate
2. Update your application code

For the following example scenario, assume you want to add a "profile" feature to the app where users can create a profile and write a short bio about themselves.

The first step is to add a new table, e.g. called Profile, to the database. You can do this by adding a new model to your Prisma schema file file and then running a migration afterwards:

// ./prisma/schema.prisma

model User {
  id      Int      @default(autoincrement()) @id
  name    String?
  email   String   @unique
  posts   Post[]
+ profile Profile?
}

model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  title     String
  content   String?
  published Boolean  @default(false)
  viewCount Int      @default(0)
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
}

+model Profile {
+  id     Int     @default(autoincrement()) @id
+  bio    String?
+  user   User    @relation(fields: [userId], references: [id])
+  userId Int     @unique
+}

Once you've updated your data model, you can execute the changes against your database with the following command:

npx prisma migrate dev --name add-profile

This adds another migration to the prisma/migrations directory and creates the new Profile table in the database.

You can now use your PrismaClient instance to perform operations against the new Profile table. Those operations can be used to implement new pages in the app.

If you want to try this example with another database than Postgres, you can adjust the the database connection in prisma/schema.prisma by reconfiguring the datasource block.

Learn more about the different connection configurations in the docs.

npm uninstall @prisma/extension-accelerate

- const prisma = new PrismaClient().$extends(withAccelerate())
+ const prisma = new PrismaClient()

  provider = "sqlite"
  url      = env("DATABASE_URL")
}

  provider = "mysql"
  url      = env("DATABASE_URL")
