import React from 'react';

export type CompositeComponent<P> = React.NonExistent<P>;

Fixed Code ✔️

When trying to import a type that is missing in an external namespace, then you have to add the missing typings yourself:

import React from 'react';

declare global {
  namespace React {
    type NonExistent<P> = React.FunctionComponent<P>;
  }
}

export type CompositeComponent<P> = React.NonExistent<P>;
