In this tutorial, you'll create a Next.js application that uses Tailwind CSS for styling and Prisma to connect to a PlanetScale database.
Set up the database
If this is your first time in the dashboard, you'll be prompted to go through a database creation walkthrough where you'll create a new database. Otherwise, click "New database" > "Create new database".
- Name — You can use any name with lowercase, alphanumeric characters, or underscores. We also permit dashes, but don't recommend them, as they may need to be escaped in some instances.
- Region — Choose the region closest to you or your application. It's important to note if you intend to make this branch a production branch, you will not be able to change the region later, so choose the region with this in mind.
Finally, click "Create database".
A development branch,
main, is automatically created when you create your database. You can use this branch to develop on, and once you're happy with any schema changes, you can promote it to production, where it becomes a highly available, protected database that you can connect your production application to.
Set up the starter Next.js app
Now that you have your database, clone the Next.js starter repository, or grab your own project.
git clone https://github.com/planetscale/nextjs-starter
Install the dependencies with:
cd nextjs-starter npm install
.env file by renaming the
.env.example file to
mv .env.example .env
Generate a connection string
Next, you need to generate a database username and password so that you can use it to connect to your application.
In your PlanetScale dashboard, select your database, click "Connect", and select "Prisma" from the "Connect with" dropdown.
As long as you're an organization administrator, this will generate a username and password that has administrator privileges to the database.
DATABASE_URL string from the
.env tab and paste it into your own
.env file. The structure will look like this:
Your PlanetScale database should now be connected to your application.
Add the schema and data
With the database connected, you're now ready to add a schema, and read/write data.
The sample repo we shared above includes a pre-built schema and some seed data built with Prisma. Push the database schema to your PlanetScale database with:
npx prisma db push
Run the seed script. This will populate your database with
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.
Deploy your app
After you have your application running locally, you may want to deploy it to production. To do so, promote your database branch (
main by default) to be the production branch (read the branching documentation for more information).
You can do this in the PlanetScale dashboard by clicking the "Branches" tab, and then clicking the "Promote a branch to production" button either in the banner or under the "...".
Deploy to Vercel
If you'd like to deploy to Vercel, check out our Deploy to Vercel documentation.
Deploy to Netlify
If you'd like to deploy to Netlify, check out our Deploy to Netlify documentation.
Netlify.tomlfile in this repository includes the configuration for you to customize the
PLANETSCALE_PRISMA_DATABASE_URLproperty on the initial deploy.
Once you're done with development, you can promote your
main branch to production to get a highly available branch protected by direct schema changes.
