javascript - 样式组件的 "css" Prop 和 Storybook 的 TypeScript 问题

Question

我在启用 styled-component 的 css 时遇到问题一旦我从 Storybook 导入某些内容，就会在 TypeScript 中使用 Prop ，因为 Storybook 依赖于 @emotion/core ，其类型声明定义了 Emotion 自己的 css支柱。错误源于两个 css Prop 类型不兼容。
我熟悉 recommended way启用 css TypeScript 中的 prop(包括 answer on Stack Overflow )，以及关于 how to handle 的建议上面解释的故事书问题。
这是应用程序代码，index.tsx :

import React from 'react'
import { css } from 'styled-components'

export default function App() {
  return (
    <h1
      css={css`
        color: red;
      `}
    >
      Hello world!
    </h1>
  )
}

这是类型声明，styled-components.d.ts ，其中包含尝试的修复:

import { CSSProp } from "styled-components";

// https://github.com/DefinitelyTyped/DefinitelyTyped/issues/31245#issuecomment-780019806

declare module 'react' {
  interface DOMAttributes<T> {
    css?: CSSProp
  }
}
declare global {
  namespace JSX {
    interface IntrinsicAttributes {
      css?: CSSProp
    }
  }
}

这一直有效，直到我在 index.tsx 中导入某些内容来自导入 @emotion/core 的 Storybook ， 例如:

import { storiesOf } from '@storybook/react'
// ...

然后 TypeScript 失败并出现以下错误:

index.tsx:8:7 - error TS2322: Type 'FlattenSimpleInterpolation' is not assignable to type 'InterpolationWithTheme<any>'.
  Type 'readonly SimpleInterpolation[]' is not assignable to type 'ObjectInterpolation<undefined>'.
    Types of property 'filter' are incompatible.
      Type '{ <S extends SimpleInterpolation>(predicate: (value: SimpleInterpolation, index: number, array: readonly SimpleInterpolation[]) => value is S, thisArg?: any): S[]; (predicate: (value: SimpleInterpolation, index: number, array: readonly SimpleInterpolation[]) => unknown, thisArg?: any): SimpleInterpolation[]; }' is not assignable to type 'string | string[] | undefined'.
        Type '{ <S extends SimpleInterpolation>(predicate: (value: SimpleInterpolation, index: number, array: readonly SimpleInterpolation[]) => value is S, thisArg?: any): S[]; (predicate: (value: SimpleInterpolation, index: number, array: readonly SimpleInterpolation[]) => unknown, thisArg?: any): SimpleInterpolation[]; }' is missing the following properties from type 'string[]': pop, push, concat, join, and 27 more.

8       css={css`
        ~~~

  node_modules/@emotion/core/types/index.d.ts:84:5
    84     css?: InterpolationWithTheme<any>
           ~~~
    The expected type comes from property 'css' which is declared here on type 'DetailedHTMLProps<HTMLAttributes<HTMLHeadingElement>, HTMLHeadingElement>'

styled-components.d.ts:7:5 - error TS2717: Subsequent property declarations must have the same type.  Property 'css' must be of type 'InterpolationWithTheme<any>', but here has type 'CSSProp<any> | undefined'.

7     css?: CSSProp
      ~~~

  node_modules/@emotion/core/types/index.d.ts:84:5
    84     css?: InterpolationWithTheme<any>
           ~~~
    'css' was also declared here.

styled-components.d.ts:13:7 - error TS2717: Subsequent property declarations must have the same type.  Property 'css' must be of type 'InterpolationWithTheme<any>', but here has type 'CSSProp<any> | undefined'.

13       css?: CSSProp
         ~~~

  node_modules/@emotion/core/types/index.d.ts:96:7
    96       css?: InterpolationWithTheme<any>
             ~~~
    'css' was also declared here.

Here's the CodeSandbox创建自 this repository它重现了这个问题。

根据 styled-components 的文档库，看来您应该导入 style而不是 css .
我创建了一个示例来展示如何做到这一点:

或者，您可以尝试转换 css作为其他东西，虽然我不确定它是否有助于解决您遇到的类型定义冲突。

import { css as StyledCss } from 'styled-components';

希望这会有所帮助。
