customizing error messages

Hi, I'm just trying this library and so far looks very promising. I cannot, however, find anywhere if it is possible to have different error messages for different validators (for a single field)? For example in Zod I could do sth like this: z.array().min(2, 'choose at least 2').max(3, 'choose no more than 3') Is there an equivalent in ArkType?

Hey glad you're enjoying it! This would be the easiest way:

const strings = type("string[]")
    .atLeastLength({
        rule: 2,
        "meta.message": "choose at least 2"
    })
    .atMostLength({
        rule: 3,
        "meta.message": "choose no more than 3"
    })

const strings = type("string[]")
    .atLeastLength({
        rule: 2,
        "meta.message": "choose at least 2"
    })
    .atMostLength({
        rule: 3,
        "meta.message": "choose no more than 3"
    })
