Disabling Output Validation

By default, oRPC validates procedure outputs against their defined schemas. If you only define output schemas for OpenAPI specification generation, you can disable output validation to improve performance.

Configuration

Set initialOutputValidationIndex to NaN:

import { os } from '@orpc/server'

const base = os
  .$config({
    initialOutputValidationIndex: Number.NaN,
  })

All procedures built from base will have output validation disabled.
