Connect a Next.js application to PlanetScale

Spin up a PlanetScale MySQL serverless database in seconds and connect to a Next.js application

In this tutorial, you'll create a Next.js application that uses Tailwind CSS for styling and Prisma to connect to a PlanetScale database.


pscale auth login

Set up the database

Create a new database with the following command:

pscale database create <DATABASE_NAME>

A branch, main, was automatically created when you created your database, so you can use that for BRANCH_NAME in the steps below.

Set up the starter Next.js app

Clone the starter repository.

git clone

Install the dependencies.

cd nextjs-starter
npm install

Next, you'll need to create a database username and password through the CLI to connect to your application. If you'd prefer to use the dashboard for this step, you can find those instructions in the Connection Strings documentation and then come back here to finish setup.

First, create your .env file by renaming the .env.example file to .env:

mv .env.example .env

Next, using the PlanetScale CLI, create a new username and password for the branch of your database:

pscale password create <DATABASE_NAME> <BRANCH_NAME> <PASSWORD_NAME>

The PASSWORD_NAME value represents the name of the username and password being generated. You can have multiple credentials for a branch, so this gives you a way to categorize them. To manage your passwords in the dashboard, go to your database overview page, click "Settings", and then click "Passwords".

Take note of the values returned to you, as you won't be able to see this password again.

Password production-password was successfully created.
Please save the values below as they will not be shown again
--------------------- -------------- ----------------------------------- ------------------ -------------------------------------------------------
production-password xxxxxxxxxxxxx Can Read & Write pscale_pw_xxxxxxx

You'll use these properties to construct your connection string, which will be the value for DATABASE_URL in your .env file. Update the DATABASE_URL property with your connection string in the following format:


Push the database schema to your PlanetScale database using Prisma.

npx prisma db push

Run the seed script to populate your database with Product and Category data.

npm run seed

Run the app

Run the app with following command:

npm run dev

Open your browser at localhost:3000 to see the running application.


After you've got your application running locally, it's time to deploy it. To do so, you'll need to promote your database branch (main by default) to be the production branch (read the branching documentation for more information).

pscale branch promote <DATABASE_NAME> <BRANCH_NAME>

Now that your branch has been promoted to production, you can either use the existing password you generated earlier for running locally or create a new password. Regardless, you'll need a password in the deployment steps below.

Choose one of the following deploy buttons and make sure to update the DATABASE_URL variable during this setup process.

Deploy on Vercel
