Major improvements

Improvements to Prisma Client for Data Proxy

In this release, we're shipping a couple of improvements to Prisma Client for Data Proxy.

The Prisma Data Proxy provides connection management and pooling for database connections for efficiently scaling database connections in serverless environments. The Prisma Client for Data Proxy provides support for connecting to the Prisma Data Proxy using HTTP.

We introduced this feature in version 3.3.0 and constantly shipped features, fixes, and improvements.

One of the changes in this release is improving the Prisma Client for the Data Proxy generation step.

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

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

You can generate Prisma Client for the Data Proxy it by using the --data-proxy flag:

npx prisma generate --data-proxy

We also updated how you can run Prisma Client using the Data Proxy in Cloudflare Workers and Edge environments. You can now use @prisma/client/edge instead of @prisma/client in your application.

import { PrismaClient } from '@prisma/client/edge'

To learn more, check out our documentation.

Prisma Client Metrics is now in Preview

Metrics is a new Preview feature that allows you to monitor how Prisma Client interacts with your database. Metrics expose a set of counters, gauges, and histograms that can be labeled and piped into an external monitoring system like Prometheus or StatsD.

You can use metrics in your project to help diagnose how your application's number of idle and active connections changes with counters, gauges, and histograms.

To get started using metrics in your project, enable the Preview feature flag in your Prisma schema:

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

You can then get started using metrics in your project:

import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

const metrics = await prisma.$metrics.json()
console.log(metrics)

To learn more, check out the metrics documentation. Give it a try and let us know what you think.

Regression

Azure SQL on MacOS

This release includes a known regression when connecting to Azure SQL from MacOS only and will be resolved soon. Follow this issue for updates and resolution.

Fixes and improvements

`migrate reset` returns with a non-0 exit code if the seed script returns with a non-0 exit code

This will help user scripts know more about the success of the command, but might break existing scripts.
