How to check the number of props that a record has?

[Dacaramo]

I've read the docs and I could not find a built in function to check if a record has an exact number of props. Maybe something like keys(n) for checking if the record has an exact n number of props and minKeys(n), maxKeys(n) to check if the record has at least or at most that n number of props.

I am missing something? If not I will love to hear how to implement those validations.

Thank you!

Great idea! Yes, maybe we should add minEntries and maxEntries. Feel free to create an issue. In the meantime you can use check. See this playground.

import * as v from 'valibot';

const Schema = v.pipe(
  v.record(v.string(), v.number()),
  v.check(
    (input) => Object.keys(input).length >= 3,
    'Please provide at least 3 entries',
  ),
);
