schemaType

Type a procedure schema slot from a plain TypeScript type, with no runtime validation.

schemaType<T>() fills a procedure schema slot from a TypeScript type instead of a runtime schema. It produces a Standard Schema that passes every value through unchanged, so the slot is fully typed but nothing is validated at runtime. Reach for it when a value is already trusted or validated elsewhere and you only want the types.

Parameters

schemaType<TInput, TOutput = TInput>(schema?)

schema

Optional. An existing Standard Schema to wrap and re-type. Omit it to get the pass-through schema that validates nothing. TOutput defaults to TInput when you supply only one type argument.

Returns

A Schema<TInput, TOutput> you assign to any schema slot on a procedure: input, output, params, query, body, or headers. The slot's inferred type comes from the type arguments, not from parsing a value.

A slot typed with schemaType is not validated. Use a real schema (Zod, Valibot, ArkType) for anything a client sends that you don't otherwise trust.

Examples

Type an output from an existing interface, with no schema to maintain:

src/lib/kizlo/server/content/index.ts
import { createProcedure, schemaType } from "kizlo"

interface Featured {
  id: number
  headline: string
}

const get = createProcedure(
  {
    scope: "internal",
    output: schemaType<Featured[]>(),
  },
  async ({ context }) => loadFeatured(context),
)

createProcedure

Define a single API operation with its scope, schemas, errors, middleware, and handler.

createMiddleware

Define reusable logic that runs before a procedure's handler to guard access, extend the context, or wrap the call.
