Cloudflare D1 (Preview)

This release brings Preview support for Cloudflare D1 with Prisma ORM 🥳

D1 is Cloudflare’s SQLite database that can be used when deploying applications with Cloudflare.

When using Prisma ORM with D1, you can continue to: model your database with Prisma schema language, specify sqlite as your database provider in your Prisma schema, and interact with your database using Prisma Client.

To use Prisma ORM and D1 on Cloudflare Workers or Cloudflare Pages, you need to set sqlite as your database provider and use the @prisma/adapter-d1 database adapter via the driverAdapters Preview feature, released back in version 5.4.0.

Here is an example of sending a query to your D1 database using Prisma Client in your Worker:

// src/index.ts file
import { PrismaClient } from '@​prisma/client'
import { PrismaD1 } from '@​prisma/adapter-d1'

// Add the D1Database to the Env interface
export interface Env {
// This must match the binding name defined in your wrangler.toml configuration
  DB: D1Database
}

export default {
  async fetch(
    request: Request,
    env: Env,
    ctx: ExecutionContext
  ): Promise<Response> {
    // Make sure the database name matches the binding name in wrangler.toml and Env interface
    const adapter = new PrismaD1(env.DB)
    // Instantiate PrismaClient using the PrismaD1 driver adapter
    const prisma = new PrismaClient({ adapter })

    const users = await prisma.user.findMany()
    const result = JSON.stringify(users)
    return new Response(result)
  },
}

createMany() for SQLite

Bringing support for createMany() in SQLite has been a long-awaited and highly requested feature ⭐

createMany() is a method on Prisma Client, released back in version 2.16.0, that lets you insert multiple records into your database at once. This can be really useful when seeding your database or inserting bulk data.

Here is an example of using createMany() to create new users:

const users = await prisma.user.createMany({
  data: [
    { name: 'Sonali', email: '[email protected]' },
    { name: 'Alex', email: '[email protected]' },
    { name: 'Yewande', email: '[email protected]' },
    { name: 'Angelina', email: '[email protected]' },
  ],
})

Before this release, if you wanted to perform bulk inserts with SQLite, you would have most likely used $queryRawUnsafe to execute raw SQL queries. But now you don’t have to go through all that trouble 🙂

With SQLite, createMany() works exactly the same way from an API standpoint as it does with other databases except it does not support the skipDuplicates option. At the behavior level, SQLite will split createMany() entries into multiple INSERT queries when the model in your schema contains fields with attributes like @default(dbgenerated()) or @default(autoincrement()) and when the fields are not consistently provided with values across the entries.

Fixes and Improvements

Prisma Client

• N+1 Issue with Decimal data type and combining queries (batching)
• Batched findUnique() error out when the field is of Boolean type
• relationJoins MySQL converts nested Decimal to float
• Unexpected query leading to querying full table when using batched findUnique()
• node-postgres (pg) errors with misleading P2010 PrismaClientKnownRequestError when using @prisma/adapter-pg with SSL (?sslmode=require)
• D1 DateTime type does not work

Edge function support for Cloudflare and Vercel (Preview)

We’re thrilled to announce that support for edge function deployments with Prisma ORM is now in Preview 🥳 As of this release, you can deploy your apps that are using Prisma ORM to:

• Vercel Edge Functions and Vercel Edge Middleware
• Cloudflare Workers and Cloudflare Pages

In order to deploy to an edge function, you’ll need to use a compatible database driver (along with its Prisma driver adapter):

• Neon Serverless Driver (for PostgreSQL databases hosted via Neon)
• PlanetScale Serverless Driver (for MySQL databases hosted via PlanetScale)
• pg driver (for traditional PostgreSQL databases)
• @libsql/client driver (for SQLite databases hosted via Turso)

Check out our documentation to learn how you can deploy an edge function using any combination of supported edge function provider and database.

You can also read more about it in the announcement blog post!

Performance improvements in nested create operations

With Prisma ORM, you can create multiple new records in nested queries, for example:

const user = await prisma.user.update({
  where: { id: 9 },
  data: {
    name: 'Elliott',
    posts: {
      create: {
        data: [{ title: 'My first post' }, { title: 'My second post' }],
      },
    },
  },
})

In previous versions, Prisma ORM would translate this into multiple SQL INSERT queries, each requiring its own roundtrip to the database. As of this release, these nested create queries are optimized and the INSERT queries are sent to the database in bulk in a single roundtrip. These optimizations apply to one-to-many as well as many-to-many relations.

With this change, using the nested create option to create multiple records effectively becomes equivalent to using a nested createMany operation (except that createMany only works with one-to-many relations, whereas create works both with one-to-many and many-to-many).

Note: Only the deepest nested operation is optimized. If a user specified create (1) -> create (2) -> create (3) in their query, only create (3) will be optimized.
