how can I get mini-css-extract-plugin to minify my files - reactjs

Getting bundle.css generated inside the dist folder but it is not getting minified. I'm Manually loading them in my html files like this: <link rel="stylesheet" href="../static/dist/bundle.css">. Also importing the style files in index.js like so : import "../css/style.css";. How do i get this to minify?
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
mode: "development",
entry: ["./static/js/index.js"],
output: {
path: path.resolve(__dirname, "static/dist"),
filename: "bundle.js"
},
watch: true,
module: {
rules: [
{
test: /\.m?js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['#babel/preset-env', "#babel/preset-react"],
plugins: [
['#babel/plugin-proposal-object-rest-spread'],
['#babel/plugin-proposal-class-properties']
]
}
}
},
{
test: /\.css$/,
use: [
{
loader: MiniCssExtractPlugin.loader,
},
'css-loader'
]
}
]
},
plugins: [
new MiniCssExtractPlugin({
filename: "./bundle.css",
}),
]

Webpack Error - You may need an appropriate loader to handle this file type,

I was trying to add webpack config in my react project, but i am facing issue as when i run the project , i get an error which says -
ERROR in ./src/index.js 14:2
Module parse failed: Unexpected token (14:2)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

| ReactDOM.render(
> <React.StrictMode>
| <App/>
| </React.StrictMode>,
here below is my configuration for webpack.config.js
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
entry: path.join(__dirname, "src", "index.js"),
output: {
path: path.resolve(__dirname, "dist"),
},
module: {
rules: [
{
test: /\.?js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
options: {
presets: ["#babel/preset-env", "#babel/preset-react"],
},
},
},
],
},
plugins: [
new HtmlWebpackPlugin({
template: "./public/index.html",
filename: "./index.html",

new MiniCssExtractPlugin(),

Your configuration has 2 module keys. They conflict with each other. Merging them should resolve your issue:
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
entry: path.join(__dirname, "src", "index.js"),
output: {
path: path.resolve(__dirname, "dist"),
},
plugins: [
new HtmlWebpackPlugin({
template: "./public/index.html",
filename: "./index.html",
}),
new MiniCssExtractPlugin(),
],
resolve: {
extensions: [".js", ".jsx"],
},
module: {
rules: [
{
test: /\.?js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
options: {
presets: ["#babel/preset-env", "#babel/preset-react"],
},
},
},
{
test: /\.css$/i,
use: [
MiniCssExtractPlugin.loader, // instead of style-loader

what is the right webpack configuration for scss files with style, css and sass loader

at first i was getting error that scss files are not readable, when i tried to add options for sass loader to set its path to node_modules. But after that i could not solve this error. Is there anyother way to add multiple loaders and options for them?
this is my webpack.config.js"
var webpack = require('webpack');
const {CleanWebpackPlugin} = require('clean-webpack-plugin');
var BundleTracker = require('webpack-bundle-tracker');
var ExtractText = require('extract-text-webpack-plugin');

Webpack 3.0: How can I exclude node_modules from build?

I tried to add 'target:node' to the webpack.dev.js to exclude node_modules from my bundle file. This results in an error. Now I have 'target:web' but has the node_modules back in. This is my config file for the applicationpart(trying to use DllReferencePlugin):
var path = require("path");
var webpack = require("webpack");
module.exports = {

},
output: {

How can I exclude the node_modules folder from the ha.js (app bundle) build? for the complete code see here
Here an example:
rules: [
{
test: /\.js$/,
exclude: /(node_modules)/, // <---

loader: 'babel-loader',
options: {

How to use webpack HotModuleReplacementPlugin to build two html website

I use webpack HotModuleReplacementPlugin to let my website could hot reload when I fix the code.
But I don't know how to build two html page.
I want to build two page "index.html" & "introduction.html"
Now I use these code in my webpack.config.js but it will have a problem, in the Chrome dev tool would show
「Uncaught Error: _registerComponent(...): Target container is not a DOM element.」
How could I solved these problem?

Using react-infinite-calendar with css-modules

I'd like to use react-infinite-calendar component for a personal project. It's not picking up the css. I think my webpack configuration is the problem as I'm using react-css-modules.
Could someone show me what I'd need to do to get it working?
My webpack configuration is:
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');
module.exports = {
entry: './index.js',
context: path.join(__dirname, 'client'),
devtool: 'source-map',
output: {
path: './dist/client/',
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.json$/,
loader: 'json-loader'
},
{
// https://github.com/gajus/react-css-modules
test: /\.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
}
]
},
resolve: {
extensions: ['', '.js', '.json']
},
plugins: [
new CopyWebpackPlugin([
{from: 'static/index.html'}
])
]
};
My date selector component is:
import React from 'react';
import InfiniteCalendar from 'react-infinite-calendar';
import 'react-infinite-calendar/styles.css'; // only needs to be imported once
import {TODAY} from '../../server/constants/date';
export default class DateSelector extends React.Component {
render() {
return (
<div>
<InfiniteCalendar
width={400}
height={600}
selectedDate={TODAY}
maxDate={TODAY}
/>
</div>
);
}
}
Another option is to exclude react-infinite-calendar from your CSS module loader and include it in the standard CSS loader.
That way you don't have to rename all of your CSS files.
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.css$/,
exclude: /react-infinite-calendar/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]',
},
{
test: /\.css$/,
include: /react-infinite-calendar/,
loader: 'style-loader!css-loader',
},
]
I worked around this by having to separate webpack loaders for locally scoped css-modules and globally scoped ones. My webpack configuration is below and so for css modules I've had to name the files so they end with .module.css.
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');
module.exports = {
entry: './index.js',
context: path.join(__dirname, 'client'),
devtool: 'source-map',
output: {
path: './dist/client/',
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.json$/,
loader: 'json-loader'
},
{
// https://github.com/gajus/react-css-modules
test: /\.module.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
},
{
test: /^((?!\.module).)*css$/,
loader: 'style-loader!css-loader'
},
]
},
resolve: {
extensions: ['', '.js', '.json']
},
plugins: [
new CopyWebpackPlugin([
{from: 'static/index.html'}
])
]
};
