; }; To use a PlanetScale database with Vercel, there are a few prerequisites: * A PlanetScale database — If you haven't created a database, refer to our [PlanetScale quickstart guide](/docs/vitess/tutorials/planetscale-quick-start-guide) to get started * A [Vercel account](https://vercel.com/) * A project deployed to Vercel — If you're just poking around and don't already have an application to deploy, you can use our [Next.js + PlanetScale sample](/docs/vitess/tutorials/connect-nextjs-app) ## Get your connection string from PlanetScale In your [PlanetScale dashboard](https://app.planetscale.com), click on the database you want to connect to. Click "**Connect**". Create a new password. Make sure to copy the password, as you'll only be shown it once. Select the framework you're using from the "**Select your language or framework**" section. This will give you the exact environment variable names you need for your selected framework. If your framework is not listed, choose "Other". PlanetScale dashboard connect modal {priority}

Keep this page open, as you'll need to copy these to Vercel momentarily. If you navigate away from the page, and can no longer access the password, create a new password by repeating steps 1-5. ## Copy environment variables to Vercel Go to your Vercel dashboard. Click on your Vercel project. Click "**Settings**". Click "**Environment variables**". Copy each value from your PlanetScale dashboard into a new environment variable in Vercel. Once you're done with one, click "**Add**" and continue to the next, if applicable. For example, if you're using Prisma, your connection string will look similar to this: ```bash theme={null} DATABASE_URL='mysql://xxxxxxxxx:************@xxxxxxxxxx.us-east-3.psdb.cloud/my_database?sslaccept=strict' ``` In Vercel, you'll set it as follows: * **NAME** = `DATABASE_URL` * **VALUE** = `mysql://xxxxxxxxx:************@xxxxxxxxxx.us-east-3.psdb.cloud/my_database?sslaccept=strict` The credentials are blurred for the example, but when you paste them in, use the actual values.
