使用Next.js渲染normalize.css +情感样式

标签: css-modules next.js emotion ssr

我正在尝试将Normalize.css添加为全局,并为我的CSS模块使用情感。

首先是我的.babelrc

{
  "presets": [
    ["env", {
      "modules": false,
      "useBuiltIns": true
    }],
    "next/babel"
  ],
  "plugins": [
    "syntax-dynamic-import",
    "transform-runtime",
    "transform-decorators-legacy",
    "transform-class-properties",
    "transform-object-rest-spread",
    "es6-promise",
    ["module-resolver", {
      "root": ["./src"],
      "alias": {
        "styles": "./styles",
        "assets": "./assets",
      },
      "cwd": "babelrc"
    }],
    ["inline-import", { "extensions": [".css"] } ],
    ["emotion", { "inline": true }]
  ]
}

添加Normalize.css

在我的_document.js我添加了规范化

import Document, { Head, Main, NextScript } from 'next/document';
import normalize from 'normalize.css/normalize.css';
import { extractCritical } from 'emotion-server';

export default class MyDocument extends Document {
  static getInitialProps({ renderPage }) {
    const page = renderPage();
    const styles = extractCritical(page.html);
    return { ...page, ...styles };
  }

  constructor(props) {
    super(props);
    const { __NEXT_DATA__, ids } = props;
    if (ids) {
      __NEXT_DATA__.ids = ids;
    }
  }

  render() {
    return (
      <html>
        <Head>
          <title>SSR</title>
          <style jsx global>{normalize}</style>
          <style dangerouslySetInnerHTML={{ __html: this.props.css }} />
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </html>
    );
  }
}

使用Emotion添加我的css模块

import React, { Component } from 'react';
import Breadcrumb from 'components/Breadcrumb';
import Link from 'next/link';
import styled, { hydrate, keyframes, css, injectGlobal } from 'react-emotion';

// Adds server generated styles to emotion cache.
// '__NEXT_DATA__.ids' is set in '_document.js'
if (typeof window !== 'undefined') {
  hydrate(window.__NEXT_DATA__.ids);
}


  const basicStyles = css`
    background-color: white;
    color: cornflowerblue;
    margin: 3rem 0;
    padding: 1rem 0.5rem;
  `

  const Basic = styled.div`
    ${basicStyles};
  `

export default class extends Component {
  render() {
    return (
      <Basic>
        <p>Basic style rendered by emotion</p>
      </Basic>);
  }
}

答案 0 :(得分:1)

在Zeit的样式-jsx页面上看起来有一个问题:https://github.com/zeit/styled-jsx/issues/298

根据此问题,它是外部样式或您需要将css标记添加到模板文字中。

查看您的代码,您使用的是css标记,但没有看到任何导致此问题的外部风格。如果你没有得到明确的答案,我会说要跟着Zeit跟进问题298。 HTH,干杯!

修改

去除那里的jsx样式,只需将normalize添加到全局模板字符串中:

injectGlobal`
    ${normalize}
    html, body {
      padding: 3rem 1rem;
      margin: 0;
      background: papayawhip;
      min-height: 100%;
      font-family: Helvetica, Arial, sans-serif;
      font-size: 24px;
    }
  `;

我对此有一个附加的答案,该答案在TypeScriptNextJS 9中效果很好。它还可以直接根据您的node_modules进行导入。

Import raw-loader(针对模块):

yarn add raw-loader

global.d.ts中,为原始加载程序定义一个钩子

declare module '!!raw-loader!*' {
  const contents: string;
  export = contents;
}

在名为Meta的组件中,我将_document.tsx放在其中(也可以使用_app.tsx,但是_document可确保SSR),

import normalizeCss from '!!raw-loader!normalize.css';

const Meta = () => (
  <div>
    <Global
      styles={css`
        ${normalizeCss}
        body {
          // ...
        }
      `}
     ></Global>
  </div>
);

export default Meta;
