我正在尝试将Webpack 4配置为将Sass用于MERN项目。当我使用 mini-css-extract-plugin 并导出CSS文件,然后将其链接到index.html文件中时,它将起作用。但是,当我尝试将css与bundle.js文件捆绑在一起时,它不会呈现css,奇怪的是,它不会呈现其中的一部分。我尝试遵循官方的引导程序webpack安装,但未按预期工作。
以下是文件:
webpack.config.js:
const path = require('path');
// const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
entry: './client/src/index.js',
mode: 'development',
module: {
rules: [
{
test: /\.s?css$/,
exclude: /node_modules/,
use: [
{
loader: 'style-loader',
},
{
loader: 'css-loader',
options: {
localIdentName: '[name]__[local]__[hash:base64:5]',
modules: true,
importLoaders: 1,
sourceMap: true,
},
},
{
loader: 'sass-loader'
},
],
},
{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel-loader",
options: {
presets: ['@babel/preset-env']
}
},
{
test: /\.jsx$/,
exclude: /node_modules/,
loader: "babel-loader",
options: {
presets: ['@babel/preset-env']
}
}
]
},
output: {
path: path.resolve(__dirname, 'client/public'),
filename: 'bundle.js'
}
}
./ client / src / index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import 'bootstrap';
import '../sass/style.scss'
import App from './components/App';
ReactDOM.hydrate(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById('root')
)

我相信webpack 4支持MiniCssExtractPlugin
,您尝试使用的其他加载器无法正常工作。
