[英]How to use imported type in React/Typescript
import { IoLogOutOutline } from 'react-icons/io5';
import { IconType } from 'react-icons';
如何使用导入的类型“图标类型”?
(alias) type IconType = (props: IconBaseProps) => JSX.Element
将图标类型设置为 JSX.Element 时,我可以将图标作为道具传递。
type LinkProps = {
to: string;
icon?: JSX.Element;
};
<Link to="logout" icon={<IoLogOutOutline />} />
但是,如果我将其设置为“图标类型”,则会返回错误:
"Type 'Element' is not assignable to type 'IconType'.
Type 'ReactElement<any, any>' provides no match for the signature '(props: IconBaseProps): Element'.ts(2322)"
IconType
是一个 function 类型,它返回一些道具并期望一个元素,因此请尝试将 function 传递给图标道具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 />} />
