如何将 Next js 与 Material UI 集成

Utk*_*oel 3 reactjs material-ui next.js

我正在使用 Next js 和 Material UI(@mui/core) 创建一个网站。当我使用 运行它时,它工作得很好next dev,但是当我使用 时,它得到了错误的样式next build && next start。除了 Material UI 之外,我还使用 CSS 模块来设计我的应用程序。
我在 Github 上找到了一个解决方案,说要在 中添加此代码_document.js,但这对我不起作用。

import * as React from "react";
import Document, { Html, Head, Main, NextScript } from "next/document";
import createEmotionServer from "@emotion/server/create-instance";
import theme from "../src/theme";
import createEmotionCache from "../src/createEmotionCache";

export default class MyDocument extends Document {
  render() {
    return (
      <Html lang="en">
        <Head>
          {/* PWA primary color */}
          <meta name="theme-color" content={theme.palette.primary.main} />
          <link rel="shortcut icon" href="/static/favicon.ico" />
          <link
            rel="stylesheet"
            href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap"
          />
          {/* Inject MUI styles first to match with the prepend: true configuration. */}
          {this.props.emotionStyleTags}
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    );
  }
}

// `getInitialProps` belongs to `_document` (instead of `_app`),
// it's compatible with static-site generation (SSG).
MyDocument.getInitialProps = async (ctx) => {
  // Resolution order
  //
  // On the server:
  // 1. app.getInitialProps
  // 2. page.getInitialProps
  // 3. document.getInitialProps
  // 4. app.render
  // 5. page.render
  // 6. document.render
  //
  // On the server with error:
  // 1. document.getInitialProps
  // 2. app.render
  // 3. page.render
  // 4. document.render
  //
  // On the client
  // 1. app.getInitialProps
  // 2. page.getInitialProps
  // 3. app.render
  // 4. page.render

  const originalRenderPage = ctx.renderPage;

  // You can consider sharing the same emotion cache between all the SSR requests to speed up performance.
  // However, be aware that it can have global side effects.
  const cache = createEmotionCache();
  const { extractCriticalToChunks } = createEmotionServer(cache);

  ctx.renderPage = () =>
    originalRenderPage({
      enhanceApp: (App) =>
        function EnhanceApp(props) {
          return <App emotionCache={cache} {...props} />;
        },
    });

  const initialProps = await Document.getInitialProps(ctx);
  // This is important. It prevents emotion to render invalid HTML.
  // See https://github.com/mui-org/material-ui/issues/26561#issuecomment-855286153
  const emotionStyles = extractCriticalToChunks(initialProps.html);
  const emotionStyleTags = emotionStyles.styles.map((style) => (
    <style
      data-emotion={`${style.key} ${style.ids.join(" ")}`}
      key={style.key}
      // eslint-disable-next-line react/no-danger
      dangerouslySetInnerHTML={{ __html: style.css }}
    />
  ));

  return {
    ...initialProps,
    emotionStyleTags,
  };
};

克隆此存储库 https://github.com/mui-org/material-ui/tree/master/examples/nextjs 并确保您已更新 _app.js 并添加 createEmotionCache(如果您使用情感)。对于元素的样式,请尝试使用 Material ui 样式而不是 CSS 模块
