How to connect Drizzle with PlanetScale in your Next.js app

PlanetScale is a MySQL-compatible serverless database, while Drizzle ORM is a TypeScript ORM that helps to interface with databases. The two have quickly become popular to use with full-stack applications built with Next.js. In this article, I'll show you how to set up and connect both in your Next.js app.

1. Install the required packages

First, we need to install the required packages. We'll need drizzle-orm and @planetscale/database to connect with PlanetScale. We'll also need drizzle-kit to generate the database schema and dotenv to load the environment variables. Assuming you've already created your Next.js app, run the following commands:

npm i drizzle-orm @planetscale/database
npm i -D drizzle-kit
npm i dotenv

2. Configure TypeScript

Drizzle does not yet support es5 and will throw the following error if you try to run it with the es5 target:

Transforming const to the configured target environment ("es5") is not supported yet.

In your tsconfig.json, change the target from es5 to es6:

// tsconfig.json

  "compilerOptions": {
    "target": "es6"

3. Connect Drizzle with PlanetScale

Go to your database at and click the Connect button in the top-right corner.

PlanetScale Connect

Pick the Drizzle option to connect with.

Copy the content of the .env file and add it to your project's .env file.


Next click on the app.ts tab and copy the code.

Go ahead and create a db/index.ts file in the root of your project and add the code you just copied. You should end up with the following:

// db/index.ts

import 'dotenv/config'
import { drizzle } from 'drizzle-orm/planetscale-serverless'
import { connect } from '@planetscale/database'

// create the connection
const connection = connect({
  host: process.env.DATABASE_HOST,
  username: process.env.DATABASE_USERNAME,
  password: process.env.DATABASE_PASSWORD,

export const db = drizzle(connection)

4. Configure Drizzle Kit

Next, we need to configure Drizzle Kit. Go back to your PlanetScale database connection settings, and this time select to connect with Prisma. We need to choose this to get the database URL. We need the database URL to make a slight modification to it.

PlanetScale Connect Prisma

Copy the URL and change the last part ?sslaccept=strict to ?ssl={"rejectUnauthorized":true}. This change will allow you to connect to your PlanetScale database from your local machine. Copy this modified URL and add it to your .env file. You should end up with the following:


Next, create a drizzle.config.ts file in the root of your project and add the following code:

// drizzle.config.ts

import 'dotenv/config'
import type { Config } from 'drizzle-kit'

export default {
  schema: './db/schema/*',
  out: './drizzle',
  driver: 'mysql2',
  dbCredentials: {
    uri: process.env.DATABASE_URL as string,
} satisfies Config

At this point, you can run local commands to connect to PlanetScale. Once you set up the database schema, you can run drizzle-kit push:mysql to push it to PlanetScale.
