Major improvements

Group By queries are now in Preview

Prisma Client now supports group by queries! Opt-in to this feature by adding the groupBy flag to the generator block in your Prisma schema:

 generator client {
   provider        = "prisma-client-js"
+  previewFeatures = ["groupBy"]
 }

 model Agent {
   id         String @id
   name       String
   location   String
   rate       Float
 }

Now you can re-generate your Prisma Client to have access to the new groupBy API:

npx prisma generate

With the updated Prisma Client, you can invoke the new groupBy query:

const locations = await client.agent.groupBy({
  by: ['location'],
  min: {
    rate: true
  },
})

// Result:
// [
//   { location: "Los Angeles", min: { rate: 10.00 } },
//   { location: "London", min: { rate: 20.00 } },
//   { location: "Tokyo", min: { rate: 30.00 } }
// ]

Prisma also supports the having side of group by, so you can further filter your groups:

const locations = await client.agent.groupBy({
  by: ['location', 'rate'],
  min: {
    rate: true
  },
  having: {
    rate: {
      gte: 20
    }
  }
})

// Result:
// [
//   { location: "London", rate: 20.00, min: { rate: 20.00 } },
//   { location: "Tokyo", rate: 30.00, min: { rate: 30.00 } }
// ]

Linux ARM64 support

Good news for Linux users! Prisma now supports Linux ARM64 out of the box. If you already generate the Prisma Client on a Linux ARM box, it will just work. To target the specific binary, you can add a binaryTarget to the generator block in your Prisma schema:

generator client {
  provider      = "prisma-client-js"
  binaryTargets = ["linux-arm-openssl-1.1.x"]
}

Prisma Migrate fix for PostGIS users

PostgreSQL users who are using the PostGIS extension can now use Prisma Migrate as well.

Breaking changes

This release introduces a breaking change for TypeScript users. Prisma Client now requires TypeScript v4.1 or above. You can read more about upgrading your TypeScript version on their wiki.
