Javascript 在Typescript中，我将如何键入此'；撰写'；功能

我正在将我的Javascript库转换为Typescript（到目前为止我所做的工作位于分支上），但我很难键入这个

compose

函数（当然，还有一些其他可组合函数，但现在是…）：

基本用法：

const componedstyledcomponent=compose.t（fn，fn，fn，…等）`
s
`

细分：

compose takes 3 args:
t(ag) = single HTML Element as property of compose or passed as ("string")
f(unctions) = composable functions (withProps(...), withStyles(...), ...etc)  -- see below for full list
s(tyles) = 
   either template literal CSS Properties:
  ` background: ${props => props.primary ? "blue" : "red" }; ` 
   
   or can be an object of CSS Properties: 
   { background: ${props => props.primary ? "blue" : "red" };

我目前拥有的：

import styled，{css}来自“styled components”；
从“./domElements”//[“a”、“缩写”、“地址”、“区域”等]
从“./types”导入{ComponentType}；
//这需要限制为任何这些可组合函数的单一使用：
//setDisplayName、withAttributes、withDefaultProps、withProps、withPropTypes、withStyles
类型函数=任意[]；
常量扩展=（…f:函数）=>
f、 减少(
（a，b）=>（…args）=>a（b（…args）），
arg=>arg
);
//可以是字符串：compose.div | compose（“div”）
//或
//它可以是React样式的组件：compose（按钮）
类型标记=字符串|组件类型

任何帮助都将不胜感激。
看看他们是如何实现styled的：

// 'const styled' is an implementation of this with defaults set
export interface ThemedBaseStyledInterface<T extends object>
    extends ThemedStyledComponentFactories<T> {
    <C extends AnyStyledComponent>(component: C): ThemedStyledFunction<
        StyledComponentInnerComponent<C>,
        T,
        StyledComponentInnerOtherProps<C>,
        StyledComponentInnerAttrs<C>
    >;
    <C extends keyof JSX.IntrinsicElements | React.ComponentType<any>>(
        // unfortunately using a conditional type to validate that it can receive a `theme?: Theme`
        // causes tests to fail in TS 3.1
        component: C
    ): ThemedStyledFunction<C, T>;
}

/'const styled'是此方法的一个实现，设置了默认值
导出接口BaseStyledInterface
扩展主题样式组件工厂{
（组件：C）：主题样式函数<
StyledComponentAnnerComponent，
T
StyledComponentNetherProps，
样式组件连接器
>;
Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '(t: Tag) => (...f: Functions) => (...s: Styles[]) => any'.
  No index signature with a parameter of type 'string' was found on type '(t: Tag) => (...f: Functions) => (...s: Styles[]) => any'.

// 'const styled' is an implementation of this with defaults set
export interface ThemedBaseStyledInterface<T extends object>
    extends ThemedStyledComponentFactories<T> {
    <C extends AnyStyledComponent>(component: C): ThemedStyledFunction<
        StyledComponentInnerComponent<C>,
        T,
        StyledComponentInnerOtherProps<C>,
        StyledComponentInnerAttrs<C>
    >;
    <C extends keyof JSX.IntrinsicElements | React.ComponentType<any>>(
        // unfortunately using a conditional type to validate that it can receive a `theme?: Theme`
        // causes tests to fail in TS 3.1
        component: C
    ): ThemedStyledFunction<C, T>;
}

class MyButton extends React.Component<ButtonProps> {
    render() {
        return <button>Custom button</button>;
    }
}

const TomatoButton = styled(MyButton)`
    color: tomato;
    border-color: tomato;
`;

// Create a <Wrapper> react component that renders a <section> with
// some padding and a papayawhip background
const Wrapper = styled.section`
    padding: 4em;
    background: papayawhip;
`;
