1。。要使用样式化的组件构建next.js应用程序,确实非常容易。您只需要使用其_document.js
片段即可启用SSR并防止页面加载时样式闪烁:https://github.com/zeit/next.js/blob/canary/examples/with-styled-components/pages/_document.js
2。。使用material-ui来构建next.js应用几乎是简单的。您只需要从另一个项目基础:https://github.com/mui-org/material-ui/tree/master/examples/nextjs开始,它就在_document.js
:https://github.com/mui-org/material-ui/blob/master/examples/nextjs/pages/_document.js
3。可悲的是,我无法弄清楚如何“合并”这两种实现并获得下一个应用程序,其中样式化组件和Material-ui组件可以共存,SSR且不会闪烁页面加载。
你能帮我吗? 互联网上是否有能力比我更好的人已经解决了这个问题,但我不知道?
先谢谢了。

这是我的_document.js
文件,如下所示:
import Document from "next/document";
import { ServerStyleSheet } from "styled-components";
export default class MyDocument extends Document {
static async getInitialProps(ctx) {
const sheet = new ServerStyleSheet();
const originalRenderPage = ctx.renderPage;
try {
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: App => props => sheet.collectStyles(<App {...props} />)
});
const initialProps = await Document.getInitialProps(ctx);
return {
...initialProps,
styles: (
<>
{initialProps.styles}
{sheet.getStyleElement()}
</>
)
};
} finally {
sheet.seal();
}
}
}
并在下面找到我的.babelrc
文件:
{
"presets": ["next/babel"],
"plugins": [
["styled-components", { "ssr": true }]
]
}

此解决方案在服务器端效果很好,对于客户端,您还需要更改注入顺序,如此处记录:https://material-ui.com/customization/css-in-js/#css-injection-order
要与next.js配合使用,您需要像这样更改jss常量的赋值:
const jss = create({
...jssPreset(),
insertionPoint: process.browser
? window.document.getElementById('jss-insertion-point')
: null
})

对于上面代码仍然有问题的每个人:我还必须在 pages/_app.tsx 中包含 StylesProvider。
_app.tsx:
import { StylesProvider } from '@material-ui/core/styles';
<StylesProvider injectFirst>
{/* Your component tree.
Now, you can override Material-UI's styles. */}
</StylesProvider>
_document.tsx:
import React from 'react';
import Document, { Head, Main, NextScript } from 'next/document';
import { ServerStyleSheets } from '@material-ui/styles';
import { ServerStyleSheet } from 'styled-components';
class MyDocument extends Document {
render() {
return (
<html lang="en">
<Head>
<meta charSet="utf-8" />
<meta
name="viewport"
content="width=device-width, initial-scale=1, shrink-to-fit=no"
/>
<meta name="theme-color" content="#000000" />
{/* Fonts and icons */}
<link
rel="stylesheet"
type="text/css"
href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700|Roboto+Slab:400,700|Material+Icons"
/>
<link
href="https://use.fontawesome.com/releases/v5.0.10/css/all.css"
rel="stylesheet"
/>
</Head>
<body>
<div id="page-transition" />
<Main />
<NextScript />
</body>
</html>
);
}
}
MyDocument.getInitialProps = async (ctx) => {
// Render app and page and get the context of the page with collected side effects.
const materialSheet = new ServerStyleSheets();
const styledComponentSheet = new ServerStyleSheet();
const originalRenderPage = ctx.renderPage;
try {
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: (App) => (props) =>
styledComponentSheet.collectStyles(
materialSheet.collect(<App {...props} />),
),
});
const initialProps = await Document.getInitialProps(ctx);
return {
...initialProps,
// Styles fragment is rendered after the app and page rendering finish.
styles: [
...React.Children.toArray(initialProps.styles),
materialSheet.getStyleElement(),
styledComponentSheet.getStyleElement(),
],
};
} finally {
styledComponentSheet.seal();
}
};
export default MyDocument;
