Bytes & JSON Details

Bytes mapping logic:

  • Default pure model output: base64 string + regex validation.
  • Set complexTypes.bytes.useBase64=false to emit Uint8Array schemas.
  • Size limits: minSize / maxSize adjust validation (base64 length scaled 4/3).
  • Allowed MIME types recorded as comments (binary mode needs external detection).

JSON mapping options (when enhanced config present):

  • Serializability refine (JSON.stringify guard)
  • Max depth & length checks
  • Null allowance toggles (record vs strict modes)

Helper: jsonMaxDepthRefinement​

Utility to append a depth guard to complex JSON array/object schemas.

import { jsonMaxDepthRefinement } from 'prisma-zod-generator';
const DeepJson = z.array(z.any())${'${jsonMaxDepthRefinement(8)}'};

Pass desired max depth; nodes beyond trigger validation error. Prefer modest limits (5–12) to avoid costly traversals.
