Highlights

Databases can only be reset manually and explicitly

In previous versions, if Prisma ORM determined that a migrate command could not be applied cleanly to the underlying database, you would get a message like this one:

? We need to reset the "public" schema at "db.url.com:5432"
Do you want to continue? All data will be lost. (y/N)

While "no" was the default, we've determined that having this prompt in the first place was a mistake. In this version we're removing the prompt entirely and instead exiting with an appropriate error message.

To get the previous behavior, you will need to run prisma migrate reset directly.

Support for prisma.config.ts in Prisma Studio

We've expanded support for our prisma.config.ts file to include Prisma Studio!

To use the new config file, including the ability to connect to driver adapter enabled databases with Prisma Studio, add a studio block to your prisma.config.ts file:

import path from 'node:path'
import type { PrismaConfig } from 'prisma'
import { PrismaLibSQL } from '@prisma/adapter-libsql'
import { createClient } from '@libsql/client'

export default {
  earlyAccess: true,
  schema: {
    kind: 'single',
    filePath: './prisma/schema.prisma',
  },
  studio: {
    adapter: async (env: unknown) => {
      const connectionString = `file:./dev.db'
      const libsql = createClient({
        url: connectionString,
      })
      return new PrismaLibSQL(libsql)
    },
  },
} satisfies PrismaConfig

Notice how this looks a little different from last release! Instead of an @prisma/config package there’s now two different options:

1. Using the defineConfig helper exported by prisma/config.
2. Using the PrismaConfig utility type exported by Prisma.

All the relevant info for the prisma.config.ts file, including these new ways of defining your config, can be found in our docs.

Allow for chaining $on and $extends.

In previous versions of Prisma ORM, the return type of the $on client method was void. This did not allow for chaining $on() and $extends() calls, as $on is not available on extended clients.

In this version we've resolved this issue and $on will now return the modified Prisma Client.
