Highlights

Prisma ORM without Rust engines for PostgreSQL & SQLite (Preview)

If you've been excited about our work of removing the Rust engines from Prisma ORM but hesitated trying it out because it was in an Early Access (EA) phase, now is a great time for you to get your hands on the Rust-free Prisma ORM version.

This major architectural change has moved from EA into Preview in this release, meaning there are no more know major issues. If you want to try it out, add the queryCompiler and driverAdapters preview feature flags to your generator, install the driver adapter for your database, and get going:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["queryCompiler", "driverAdapters"]
  output          = "../generated/prisma"
}

Now run prisma generate to re-generate Prisma Client. If you didn't use a driver adapter before, you'll need to install, e.g. the one for PostgreSQL:

npm install @prisma/adapter-pg

Once installed, you can instantiate PrismaClient as follows:

import { PrismaClient } from './generated/prisma'
import { PrismaPg } from '@prisma/adapter-pg'
const adapter = new PrismaPg({ connectionString: env.DATABASE_URL })
const prisma = new PrismaClient({ adapter })

No more hassle with query engines, binary targets and an even smoother experience in serverless and edge environments!

Major improvements for local Prisma Postgres (Preview)

In the last release, we enabled you to spin up a Prisma Postgres instance locally via the new prisma dev command. Local Prisma Postgres uses PGlite under the hood and gives you an identical experience as you get with a remote Prisma Postgres instance.

This release brings major improvements to this feature:

• Persists your databases across prisma dev invocations.
• Enables you to have multiple local Prisma Postgres instances running at the same time.
• Running prisma init now uses local Prisma Postgres by default.
