Prisma Client Extension - Input Validation

This example uses Prisma Client extensions to perform custom runtime validations when creating and updating database objects.

This technique could be used to sanitize user input or otherwise deny mutations that do not meet some criteria.

Caveats

NOTE: Query extensions do not currently work for nested operations. In this example, validations are only run on the top level data object passed to methods such as prisma.product.create(). Validations implemented this way do not automatically run for nested writes.

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

Please read the documentation on query extensions for more information.
