如何在 React/Typescript 中使用导入的类型

Question

import { IoLogOutOutline } from 'react-icons/io5';    
import { IconType } from 'react-icons';

How do I use the imported type 'Icon Type'?

(alias) type IconType = (props: IconBaseProps) => JSX.Element

I am able to pass an icon as a prop when setting the type of icon to JSX.Element.

type LinkProps = {
    to: string;
    icon?: JSX.Element;
};

<Link to="logout" icon={<IoLogOutOutline />} />

However if I set it to 'Icon Type' it returns with the error:

"Type 'Element' is not assignable to type 'IconType'.
  Type 'ReactElement<any, any>' provides no match for the signature '(props: IconBaseProps): Element'.ts(2322)"

Answer 1

IconType is a function type, that returns some props and expects an element, so try passing a function to the icon prop icon={() => <IoLogOutOutline />}

import { IoLogOutOutline } from 'react-icons/io5';    
import { IconType } from 'react-icons';

type LinkProps = {
    to: string;
    icon?: IconType;
};

function Link(props: LinkProps) {
    return ...;
}

<Link to="logout" icon={() => <IoLogOutOutline />} />
