idField

idField<Brand>(codec): IdTransform<Brand>

Defined in: src/adapters/prisma.ts:170

Creates a read/write transform pair for use with Prisma’s $extends extension model.

Requires a codec variant that exposes a synchronous generate() in addition to safeParse — see IdGeneratingCodec. Only the Timestamp codec and Reverse Timestamp codec qualify; Opaque, Signed, Wrapped, and Digest codecs cannot be passed to idField().

Use computeField(fieldName) to produce a typed $extends result-component field definition — the brand is carried through Prisma’s type machinery automatically and no per-call-site cast is required.

For codecs that do not expose a synchronous generate() (Opaque Timestamp, Signed Timestamp, Wrapped key, Digest), use idFieldNonGenerating instead — it accepts any IdColumnCodec and omits defaultQuery.

Type Parameters

Brand

Brand extends string

Parameters

codec

IdGeneratingCodec<Brand>

Returns

IdTransform<Brand>

Example

import { idField } from "@smonn/ids/prisma";
import { createTimestampId } from "@smonn/ids";

const usr = createTimestampId("usr");
const userIdField = idField(usr);

const xprisma = prisma.$extends({
  result: {
    user: { id: userIdField.computeField("id") },
  },
});
// xprisma.user.findUnique(…).id is typed as Id<"usr"> — no cast required
