Typescript: Conditional intersection type for react props

[barmaglot92]

Hi, i think that ability to describe react component props as type with non required fields but it can be required if another field exists. For instance:

interface ComponentProps {
  sortable?: boolean
  onSortHandler - this field must be required only when sortable is true moreover it must don't exists in this interface
}

So, is it possible to do with conditional types ? For now i couldn't implement it

You don't need conditional types. Some like that should work:

type ComponentProps = {
  sortable: true,
  onSortHandler: any, // set the correct type
} | {
  sortable?: false | null,
};

NOTE: better ask questions to stackoverflow.
