NoteThis doc is intended for users that are manually storing a connection string in an environment variable in Netlify. If you want to use the Netlify integration, which handles this for you, see the PlanetScale integration in the Netlify docs.

​
Prerequisites

​
Connecting your PlanetScale database to your Netlify application

​
Get your connection string from PlanetScale

1

In your PlanetScale dashboard, click on the database you want to connect to.
2

Click “Connect”.
3

Create a new password. Make sure to copy the password, as you’ll only be shown it once.
4

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”.

5

Keep this page open, as you’ll need to copy these to Netlify momentarily.
6

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 Netlify

1

Go to your Netlify dashboard.
2

Click on your Netlify project.
3

Click “Site settings”.
4

Click “Build & deploy,” then “Environment”.
5

Click “Edit variable”.
6

Click “New variable” and copy each value from your PlanetScale dashboard into a new environment variable in Netlify. 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: 
DATABASE_URL='mysql://xxxxxxxxx:************@xxxxxxxxxx.us-east-3.psdb.cloud/my-database?sslaccept=strict'
NoteYour environment variable name will be the same in your application’s code. We used DATABASE_URL as an example, but this can be given a different name.
In Netlify, you’ll set it as follows:
  • Key = DATABASE_URL
  • Value = mysql://xxxxxxxxx:************@xxxxxxxxxx.us-east-3.psdb.cloud/my-database?sslaccept=strict
NoteThe credentials are blurred for the example, but when you paste them in, use the actual values.

After you have saved, you will need to rebuild the site with the new environment variable.
