我正在尝试为我的应用程序实现服务器端渲染。它曾经是使用select * from customer where (
custName like '%param1%' OR
custAddress equals param2 OR
custNo in'List<param>)
order by custName desc;
的客户端渲染。在客户端渲染中一切正常,但是现在当我在服务器端渲染时,没有CSS表单和UI库(Reactstrap + Material UI)都被渲染。用户界面完全坏了。
我正在将App.js(具有所有UI的实际前端页面)注入html.js(模板)
我的服务器:
ReactDom
我的html.js(只是一个简单的模板):
import express from 'express';
import React from 'react';
import { renderToString } from 'react-dom/server'
import App from '../../src/App'
import Html from '../../src/html.js'
const app = express();
// console.log that your server is up and running
app.listen(3001, () => console.log(`Listening on port 3001`));
app.get('/',(req,res) => {
const title="2FA SDK"
const body = renderToString(<App/>)
res.send(
Html({
body,
title,
})
)
})
我的app.js(使用用户界面,最少)
const Html = ({ body, styles, title }) => `
<!DOCTYPE html>
<html>
<head>
<title>${title}</title>
</head>
<body style="margin:0">
<div id="app">${body}</div>
</body>
</html>
`;
使用reactstrap的App.js的一部分:
render(){
return(
<div className="container">
<div>
<TextField
label="Application Name"
type="text"
variant="outlined"
onChange={this.handleApplicationName}
/>
</div>
<div>
<FormLabel>Phone</FormLabel>
<div>
<OutlinedInput
value={this.state.textmaskArray[2]}
onChange={(e) => this.handlePhoneNumber(e,2)}
labelWidth={200}
/>
</div>
</div>
<Button variant="contained" color="primary" onClick={this.props.buttonAction}>
</Button>
</div>
) } 我的webpack.config.js:
render(){
return(
<CardControl
title={"Code Authention"}
message={"For your security, we need to verify your identity by sending a code to your phone number"}
>
<Container>
<Row>
<Col>
<div>{this.props.phoneList}</div>
</Col>
<Col>
<div>{this.props.methodList}</div>
</Col>
</Row>
<Button className="sm-2" disabled={this.props.disabled} color="info" onClick={this.props.buttonAction}>{this.props.buttonName}</Button>
</Container>
</CardControl>
我正在使用什么:const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const HtmlWebPackPlugin = require("html-webpack-plugin");
const nodeExternals = require("webpack-node-externals");
module.exports = [
{
/*Config for backend code*/
entry: './src/server/server.js',
target: 'node',
output: {
filename: 'server.js'
},
externals: [nodeExternals()],
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.html$/,
use: {
loader: "html-loader",
options: { minimize: true }
}
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader,"css-loader"]
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./public/index.html",
filename:"./index.html"
}),
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename:"[id].css"
})
]
},
]
我尝试过的事情:我安装了CSS滑块,但是根本无法正常工作。 我还查看了Material-ui关于服务器端渲染的文档,我觉得我只是缺少了一小部分,而他们提供的说明可能是一个过分的追求。
我需要帮助的地方:我试图弄清为什么material-ui或bootstrap中的UI组件根本无法渲染。我怀疑nodeExternal会将它们排除在外,但我不确定。
答案 0 :(得分:0)
您需要在客户端混合渲染的HTML,以使反应接管。
使用以下命令创建一个client.js文件:
import React from 'react';
import ReactDOM from 'react-dom';
ReactDOM.hydrate(
<App/>,
document.querySelector('#app'),
);
请注意,水合物应与renderToString
所呈现的相匹配。
接下来,将其添加为您的webpack配置中的其他条目:
module.exports = [
{
/*Config for backend code*/
entry: './src/server/server.js',
target: 'node',
output: {
filename: 'server.js'
},
externals: [nodeExternals()],
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.html$/,
use: {
loader: "html-loader",
options: { minimize: true }
}
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader,"css-loader"]
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./public/index.html",
filename:"./index.html"
}),
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename:"[id].css"
})
]
},
{
entry: './client.js',
output: {
filename: 'bundle.js',
},
module: {
rules: [ {
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
],
},
]
更改您的html渲染代码以包括以下内容:
const Html = ({ body, styles, title }) => `
<!DOCTYPE html>
<html>
<head>
<title>${title}</title>
</head>
<body style="margin:0">
<div id="app">${body}</div>
<script async src="/bundle.js"></script>
</body>
</html>
`;
对于这种确切的代码是否有效,我不是100%的自信,但这是一个普遍的想法。
