Is it possible to automatically generate a deep data type? Structure type?

Answer 1

Generate from what? what is a "deep type"? for your example - write a recursive type with your hands from several lines and it will be enough, why generate something here?

type Category = {
        title: string
        isActive: boolean
        icon: string
        child?: Category
}

In general, no one bothers you to write a generator. But in fact - they are needed very rarely, mainly if it is some kind of external data, such as gql, or you have code generated in js, such as grpc.
