["'on' | 'off'", "=", "off"] works, but I cannot convert it to boolean

You need to tell ArkType how to convert the string to a boolean. I guess what you want is

type(["'on'|'off'", "=", "off"]).pipe(v => v === "on")

type(["'on'|'off'", "=", "off"]).pipe(v => v === "on")

Do you actually need the default value?

CodeHz•2mo ago

'default?' also doen't work

^ ???

const t = type({foo: ["'on' | 'off' = 'on'", "=>", v => v === "on"]});

const t = type({foo: ["'on' | 'off' = 'on'", "=>", v => v === "on"]});

~~this seems to work~~ nvm, it fails at runtime

runtime error: Default values must be specified on objects like { isAdmin: 'boolean = false' }

Yeah, I just got the same when actually running it That's probably a bug If you don't need the default you can remove it and then it works properly If you do need the default, then I guess the best option is to just make it optional

type({"foo?": ["'on' | 'off'", "=>", v => v === "on"]})

type({"foo?": ["'on' | 'off'", "=>", v => v === "on"]})

would work

CodeHz•2mo ago

yes, I think it would be perfect
