Function: jsonNullable()

function jsonNullable<T>(inner): ZodOptional<ZodNullable<T>>;

Defined in: src/models/dlp-json-nullable.ts:24

Wraps a Zod schema for use in a JSON Merge Patch (RFC 7396) request body.

Merge-patch semantics:

• Field omitted → leave unchanged on the server.
• Field set to null → clear/null on the server.
• Field set to a value → replace on the server.

The DLP OpenAPI generator emits a JsonNullable<T> wrapper type with a present: boolean discriminator, but the actual wire shape is just T | null | undefined. This helper keeps the Zod surface minimal while documenting the intent.

Type Parameters

Type Parameter
T extends ZodTypeAny

Parameters

Parameter	Type
inner	T

ZodOptional<ZodNullable<T>>

Example

const PatchBody = z.object({
  description: jsonNullable(z.string()),
  tags: jsonNullable(z.array(z.string())),
});
// Clear `description`, leave `tags` untouched:
const body = { description: null };
