Prisma Client & Prisma schema

When we release a new Prisma Client or Prisma schema feature, it often starts in Preview so that you can test it and submit your feedback. After we improve the feature with your feedback and are satisfied with the internal test results, we promote the feature to general availability.

For more information, see ORM releases and maturity levels.

Enabling a Prisma Client Preview feature

To enable a Prisma Client Preview feature:

1. Add the Preview feature flag to the generator block:

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

2. Re-generate Prisma Client:

   npx prisma generate

3. If you are using Visual Studio Code and the Preview feature is not available in your .ts file after generating Prisma Client, run the TypeScript: Restart TS server command.
