Prisma Client Extension - Transformed Fields

This example shows how to use a Prisma Client extension to transform result fields returned by queries. In this example, a date field is transformed to a relative string for a specific locale.

This example shows a way to implement internationalization (i18n) at the data access layer in your application. However, this technique allows you to implement any kind of custom transformation or serialization/deserialization of fields on your query results.

Caveats

This extension is provided as an example only. It is not intended to be used in production environments.

Please read the documentation on result extensions for more information.
