how to handle "[key: string]: any" combined with specific keys

[aboveyunhai]

how to handle this typescript case in valibot, I search the doc and didn't find an answer.

 type Test {
    specific?: string;
    [key: string]: any;
}

since valibot will strip any additional keys away during safeParse()

Thank you for using Valibot! Here is the solution. You can read more about it in the docs: https://valibot.dev/guides/objects/

import * as v from 'valibot';

const TestSchema = v.object(
  { specific: v.optional(v.string()) },
  v.any()
);

Hint: The schema function any exists only for completeness and is not recommended in practice. Instead, unknown should be used to accept unknown data.

@fabian-hiller thx. was about to ask the question, will do the unknown for full type safety, as long as the additional field remain after parse.
