Dynamic type based on another value

Not even that. Just use a discriminated union, like you would with raw TS.

// raw TS
type t = {agree: true, clauses: "first" | "second"} | {agree: false, clauses?: "first" | "second"

// arktype
const t = type({agree: true, clauses: "'first' | 'second'"}).or({agree: false, clauses?: "'first' | 'second'"})

// raw TS
type t = {agree: true, clauses: "first" | "second"} | {agree: false, clauses?: "first" | "second"

// arktype
const t = type({agree: true, clauses: "'first' | 'second'"}).or({agree: false, clauses?: "'first' | 'second'"})

template literal/backtick string types e.g. type T = `type-${string}`

Although the inferred type would just be string

template literal/backtick string types e.g. type T = `type-${string}`

const UserId = type("string").narrow(s => s.startsWith("user-"))

const UserId = type("string").narrow(s => s.startsWith("user-"))

or whatever

You'd need to use a morph/narrow for now (probably a narrow)

It's not possible to have numbers as a key in JS

Default number

Where t in this case is your queryType

Default number

It's not clear to me what exactly you're after here, but maybe t["infer"] or t["tOut"] is what you're after?

Sort of. You could look at the internal schema structure

You just need a way of determining what keepAsString should be, which from the sounds of it you know so isn't an issue

Accept number in string type

@PIat To finally answer your question, this seems to work:

import { type } from "arktype"

const formType = type({
    intent: "'profile'",
    name: "string>0",
    surname: "string>4",
    agree: "boolean"
}).or({
    intent: "'private'",
    password: "string>0"
})

const keepAsString = ["intent", "name", "surname", "password"]

const parseNonStringFieldsToJson = type("object", "=>", obj =>
    Object.fromEntries(
        Object.entries(obj).map(([k, v]) => [
            k,
            keepAsString.includes(k) ? v : JSON.parse(v)
        ])
    )
)

const parseFormData = parseNonStringFieldsToJson.pipe(formType)
const input = {
    intent: "profile",
    name: "John",
    surname: "Doe",
    agree: "true"
}

const result = parseFormData.assert(input)
console.log(result)

import { type } from "arktype"

const formType = type({
    intent: "'profile'",
    name: "string>0",
    surname: "string>4",
    agree: "boolean"
}).or({
    intent: "'private'",
    password: "string>0"
})

const keepAsString = ["intent", "name", "surname", "password"]

const parseNonStringFieldsToJson = type("object", "=>", obj =>
    Object.fromEntries(
        Object.entries(obj).map(([k, v]) => [
            k,
            keepAsString.includes(k) ? v : JSON.parse(v)
        ])
    )
)

const parseFormData = parseNonStringFieldsToJson.pipe(formType)
const input = {
    intent: "profile",
    name: "John",
    surname: "Doe",
    agree: "true"
}

const result = parseFormData.assert(input)
console.log(result)
