Prisma Client extensions are Generally Available

Today, we’re very excited to announce that Prisma Client extensions are Generally Available and production-ready! This means you can use the feature without the clientExtensions Preview feature flag.🚀

Prisma Client extensions are a powerful new feature for adding functionality on top of your Prisma Client in a type-safe manner. With this feature, you can create simple, but flexible solutions.

Prisma Client extensions have 4 different types of components that can be included in an extension:

• Result extensions components: add custom fields and methods to query result objects, for example, virtual/computed fields.
• Model extensions components: enable you to add new methods to your models alongside existing model methods such as findMany.
• Query extensions components: let you hook into the lifecycle of a query and perform side effects, modify query arguments, or modify the results in a type-safe way. These are an alternative to middleware that provide complete type safety and can be applied in an ad-hoc manner to different extensions.
• Client extensions components: allow you to add new top-level methods to Prisma Client. You can use this to extend Prisma Client with functionality that isn’t tied to specific models.

const prisma = new PrismaClient().$extends({
  name: "extension-name",
  result: { /* ... */ },
  model: { /* ... */ },
  query: { /* ... */ },
  client: { /* ... */ },
});

You can also create and publish extensions for others to use. Learn more about how to share extensions in our documentation.
