当尝试使用 typescript 定义功能组件以与样式组件反应时，会出现“没有重载匹配此调用”的错误。

代码

type BadgeTypes = {
  success: string;
  secondary: string;
  alert: string;
  text: string;
};

type Theme = {
  fonts?: object;
  borderRadius: string;
  primary?: object;
  accent?: object;
  action?: object;
  stories?: object;
  checkbox?: object;
  badge: BadgeTypes;
  button?: object;
  page?: object;
  states?: object;
  modal?: object;
};
interface Props {
  theme: Theme;
  large: boolean;
  type: keyof BadgeTypes;
}
const StyledBadge = styled.span<Props>`
  display: inline-block;
  border-radius: ${(props: Props): string => props.theme.borderRadius};
  text-align: center;
  color: ${(props: Props): string => props.theme.badge.text};
  font-size: ${(props: Props): string => (props.large ? `1.4rem` : `1rem`)};
  padding: ${(props: Props): string =>
    props.large ? `0 .8rem` : `0.2rem 0.6rem 0.3rem 0.6rem`};
  background: ${(props: Props): string => props.theme.badge[props.type]};
`;
interface BadgeProps {
  children: React.ReactChildren;
  // any other props that come into the component
}

const Badge = ({
  children,
  ...props
//problem likely the line below
}: BadgeProps): React.FunctionComponentElement<BadgeProps> => (
  <StyledBadge {...props}>{children}</StyledBadge>
);

错误是

No overload matches this call.

我知道这可能是由于我在BadgeProps):但是经过几次谷歌搜索后我找不到合适的类型。

Answer 1

更多的是关于您的BadgeProps ，它们与Props没有任何关系。 并且由于StyledBadge具有 Props 类型的Props ，TypeScript 会大喊大叫！

为了解决这个问题，我制作了一个带有必要修复的小代码沙箱。

我还对您声明Badge组件的方式进行了一些小改动：)
