javascript - 如何在 React with Typescript 中使用 Material UI 自定义变体

Question

错误示例:https://codesandbox.io/s/flamboyant-lederberg-w16pio?file=/src/App.tsx
我正在尝试从 Mui 的类型扩展以添加更多变体。我已经从 Muis 基础 Prop 扩展了。 interface IText extends TypographyProps {我在避免必须管理 Mui 已经定义的所有类型之后。在这种确切的情况下，它在这里:

"h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline"

理论上， Prop 的最终结果是:

 "inherit" | "caption12r" | "caption12ruc" | "caption12buc" | "h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline" 

错误

TS2769: No overload matches this call.   Overload 1 of 2, '(props: { component: ElementType<any>; } & SystemProps<Theme> & { align?: "right" | "left" | "inherit" | "center" | "justify" | undefined; children?: ReactNode; ... 6 more ...; variantMapping?: Partial<...> | undefined; } & CommonProps & Omit<...>): Element', gave the following error.     Type '{ "data-name": string; component?: string | undefined; variant?: "h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline" | ... 4 more ... | undefined; ... 352 more ...; onTransitionEndCapture?: TransitionEventHandler<...> | undefined; }' is not assignable to type '{ component: ElementType<any>; }'.       Types of property 'component' are incompatible.         Type 'string | undefined' is not assignable to type 'ElementType<any>'.           Type 'undefined' is not assignable to type 'ElementType<any>'.   Overload 2 of 2, '(props: DefaultComponentProps<TypographyTypeMap<{}, "span">>): Element', gave the following error.     Type '{ "data-name": string; component?: string | undefined; variant?: "h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline" | ... 4 more ... | undefined; ... 352 more ...; onTransitionEndCapture?: TransitionEventHandler<...> | undefined; }' is not assignable to type '{ align?: "right" | "left" | "inherit" | "center" | "justify" | undefined; children?: ReactNode; classes?: Partial<TypographyClasses> | undefined; ... 5 more ...; variantMapping?: Partial<...> | undefined; }'.       Types of property 'variant' are incompatible.         Type '"h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline" | "inherit" | "caption12r" | "caption12ruc" | "caption12buc" | undefined' is not assignable to type '"h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "subtitle1" | "subtitle2" | "body1" | "body2" | "caption" | "button" | "overline" | "inherit" | undefined'.

扩展失败的代码

import React from "react";
import { Typography as MUITypography, TypographyProps } from "@mui/material";
import { OverridableStringUnion } from "@mui/types";
import { Variant } from "@mui/material/styles/createTypography";
import { TypographyPropsVariantOverrides } from "@mui/material/Typography/Typography";

interface IText extends TypographyProps {
  component?: string;
  variant?: OverridableStringUnion<
    Variant | "inherit" | "caption12r" | "caption12ruc" | "caption12buc",
    TypographyPropsVariantOverrides
  >;
}

我还尝试通过 tsModules 扩展它:

export interface EleMuiVariantOverrides {
  'icon': true;
}

declare module "@mui/material/Button/Button" {
  interface ButtonPropsVariantOverrides extends EleMuiVariantOverrides {}
}

延长Typography variant你可以这样做:

import React from "react";
import {
  Typography,
  TypographyProps,
  createTheme,
  ThemeOptions,
  ThemeProvider
} from "@mui/material";
import { TypographyOptions } from "@mui/material/styles/createTypography";

declare module "@mui/material/Typography" {
  interface TypographyPropsVariantOverrides {
    caption12r: true;
  }
}

interface ExtendedTypographyOptions extends TypographyOptions {
  caption12r: React.CSSProperties;
}

const theme = createTheme({
  typography: {
    caption12r: {
      color: "red"
    }
  } as ExtendedTypographyOptions
} as ThemeOptions);

const Text = (props: TypographyProps) => {
  return <Typography {...props} data-name="CLText" />;
};

export default function App() {
  return (
    <ThemeProvider theme={theme}>
      <div className="App">
        <Text variant="caption12r">Jamie</Text>
      </div>
    </ThemeProvider>
  );
}

在您的代码框中，我还可以看到尝试使用扩展 variant s 代表 Button ;抱歉，我对此无能为力。
