如何在使用样式组件渲染服务器端时注入全局样式

How to inject global styles while rendering server-side with styled-components

我无法从 documentation 中弄清楚这一点。

我正在尝试通过 styled-components 向服务器端呈现的 React 应用程序添加一些全局样式 - 但我不知道该怎么做。

这是我的部分 globalStyles.js:

import { injectGlobal } from 'styled-components';

export default () => injectGlobal`
    @import url('https://fonts.googleapis.com/css?family=Pacifico');
    @import url('https://fonts.googleapis.com/css?family=Open+Sans:300,400');
    html {
        box-sizing: border-box;
    }
    *, *:before, *:after {
        box-sizing: inherit;
    }
`;

这是我的通用渲染 express-handler:

const path = require('path');
const fs = require('fs');

const React = require('react');
const { renderToString } = require('react-dom/server');
const { StaticRouter } = require('react-router-dom');
const { ServerStyleSheet } = require('styled-components');

const { default: App } = require('../src/containers/App');
const baseStyles = require('../src/styles'); // How to get this in the global css

const indexFile = fs.readFileSync(path.resolve(__dirname, '..', 'build', 'index.html'), 'utf8');

function universalLoader(req, res) {
    const css = new ServerStyleSheet();
    const context = {};

    baseStyles();

    // Create the markup from the React application
    const markup = renderToString(
        css.collectStyles(
            <StaticRouter context={context} location={req.url}>
                <App />
            </StaticRouter>
        )
    );

    const html = indexFile
        .replace('{{SSR}}', markup)
        .replace('{{CSS}}', css.getStyleTags());

    // Send the response back to the user
    res.send(html);
};

事实证明,在我的 <App /> 组件 render() 方法中调用 baseStyles()(进而调用 injectGlobal)解决了问题。 :)
