Highlights

Driver adapters improvements (Preview)

In version 5.4.0, we released driverAdapters into Preview. The driverAdapters feature enables Prisma Client to access your database using JavaScript or Serverless database drivers.

In this release, we fixed many bugs for the existing driver adapters. We appreciate all the community feedback that has helped us improve this feature!

PlanetScale serverless driver adapter improvements

This release also introduces a small breaking change to the @prisma/adapter-planetscale package to improve its stability and performance. The serverless driver adapter will now use a connection pool instead of a single connection from PlanetScale’s serverless driver.

In case you’re using the @prisma/adapter-planetscale, update your Prisma Client instance with the following:

-import { connect } from '@planetscale/database'
+import { Client } from '@planetscale/database'
import { PrismaPlanetScale } from '@prisma/adapter-planetscale'
import { PrismaClient } from '@prisma/client'
import { fetch as undiciFetch } from 'undici';
-const connection = connect({ url: connectionString, fetch: undiciFetch })
+const client = new Client({ url: connectionString, fetch: undiciFetch })
-const adapter = new PrismaPlanetScale(connection)
+const adapter = new PrismaPlanetScale(client)
const prisma = new PrismaClient({ adapter })

If you run into the following error: [TypeError]: PrismaPlanetScale must be initialized with an instance of Client., you can use the following snippet when defining your Prisma Client instance:

import { createRequire } from "node:module";
import { PrismaPlanetScale } from "@prisma/adapter-planetscale";
import { fetch as undiciFetch } from 'undici';
const require = createRequire(import.meta.url);
const { Client } = require("@​planetscale/database");
const client = new Client({ url:  process.env.DATABASE_URL , fetch: undiciFetch })
const adapter = new PrismaPlanetScale(client);
