I create a project with the following structure:
Webpack 4 configuration:
const HtmlWebPackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
output: {
path: __dirname + '/web'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: ['babel-loader', 'eslint-loader']
},
{
test: /\.html$/,
use: [
{
loader: 'html-loader',
options: { minimize: true }
}
]
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader, 'css-loader']
},
{
test: /\.scss$/,
exclude: /node_modules/,
use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
},
{
test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
use: [{
loader: 'file-loader',
options: {
name: '[name].[ext]',
outputPath: __dirname + '/fonts'
}
}]
},
{
test: /\.(jpg|png)$/,
use: {
loader: "file-loader",
options: {
name(file) {
if (env === 'development') {
return './images/[name].[ext]'
}
return '[hash].[ext]'
}
}
}
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: './src/index.html',
filename: './index.html'
}),
new MiniCssExtractPlugin({
filename: '[name].css',
chunkFilename: '[id].css'
})
]
};
After compilation, the main.js, main.css and index.html are placed in the web folder. How to make all the pictures in the project copied to the web/images, and the fonts in the web/fonts?
In the project, I refer to them as follows:
1) src\Interface\Header\Index.js
<img src="img/logo.png" srcSet="img/logo#2x.png 2x, img/logo#3x.png 3x" className="header-logo" alt=""/>
2) src\Pages\App\style.css
#font-face {
font-family: 'HelveticaNeueCyr';
src: url('/fonts/HelveticaNeueCyr.woff2') format('woff2'),
url('/fonts/HelveticaNeueCyr.woff') format('woff');
font-weight: normal;
font-style: normal;
}
module.exports = {
output: {
path: __dirname + '/web'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: ['babel-loader', 'eslint-loader']
},
{
test: /\.html$/,
use: [
{
loader: 'html-loader',
options: { minimize: true }
}
]
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader, 'css-loader']
},
{
test: /\.scss$/,
exclude: /node_modules/,
use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
},
{
test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
use: [{
loader: 'file-loader',
options: {
name: '[name].[ext]',
outputPath: 'fonts'
}
}]
},
{
test: /\.(jpg|png)$/,
use: {
loader: "file-loader",
options: {
name: 'images/[name].[ext]',
outputPath: 'images'
}
}
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: './src/index.html',
filename: './index.html'
}),
new MiniCssExtractPlugin({
filename: '[name].css',
chunkFilename: '[id].css'
})
]
};

module.exports = (options) => ({

I have updated mode. Could not figure out the config issues here
mode should be in the root object and not in the module object:

So I tried creating a boilerplate for an existing project that our company have and after running the script for webpack,
it generated a ./dist/server.js however, when I run it from node, I am getting this document not found error. Please let me know if you need a code snippet of a specific file.
ERROR

I'm migrating a react website to webpack 4 (from 3) but have been running into some strange problems when using webpack for css.
It works fine for the css that I wrote myself, but any css from third party components in node_modules does not seem to be included at all.
Here is an example of my webpack config:
const webpack = require('webpack');
const path = require('path');
const LodashModuleReplacementPlugin = require('lodash-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const config = {
entry: [
'react-hot-loader/patch',
'./src/index.js'
],
output: {
path: path.resolve(__dirname, 'dist'),
filename: '[name].[contenthash].js'
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
use: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.css$/,
exclude: [/node_modules/, /global\.css$/],
use: [
MiniCssExtractPlugin.loader,
{
loader: 'css-loader',
options: {
importLoaders: 1,
modules: true,
}
},
'postcss-loader'
]
},
{
test: /\.css$/,
include: [/node_modules/, /global\.css$/],
use: [
MiniCssExtractPlugin.loader,
{
loader: 'css-loader',
options: {
importLoaders: 0,
modules: true,
}
}
]
},
{
test: /\.png$/,
use: [
{
loader: 'url-loader',
options: {
mimetype: 'image/png'
}
}
]
},
{
test: /\.svg$/,
use: 'file-loader'
},
{
test: /\.jpg$/,
use: [
{
loader: 'url-loader',
options: {
mimetype: 'image/jpg'
}
}
]
},
]
},
resolve: {
extensions: [
'.js',
'.jsx'
],
alias: {
'react-dom': '#hot-loader/react-dom'
},
modules: [
'node_modules',
],
},
devServer: {
contentBase: './dist'
},
plugins: [
new MiniCssExtractPlugin({
filename: "[name].css",
}),
new webpack.ContextReplacementPlugin(/moment[\/\\]locale$/, /en/),
new LodashModuleReplacementPlugin,
new HtmlWebpackPlugin({
template: require('html-webpack-template'),
inject: false,
appMountId: 'app',
})
],
optimization: {
runtimeChunk: 'single',
splitChunks: {
cacheGroups: {
vendor: {
test: /[\\/]node_modules[\\/]/,
name: 'vendors',
chunks: 'all'
}
}
}
}
};
module.exports = (env, argv) => {
if (argv.hot) {
// Cannot use 'contenthash' when hot reloading is enabled.
config.output.filename = '[name].[hash].js';
}
return config;
};
Only css from my own files are included in the generated bundle.
I'm using the latest versions:
"webpack": "^4.41.2",
"webpack-cli": "^3.3.10",
"webpack-dev-server": "^3.9.0"
Greatful for any help!
Layout of the project
I'm having trouble with extract-loader. I try to add background: url(../../assets/icons/upload.svg); to sass, but I get an error.
Error: Cannot find module '../../assets/icons/upload.svg' from '/home/jeremy/code/sample-project/src/styles'
Tried resolve-url-loader, but without success.
My webpack config:
module: {
rules: [
{
test: /\.(js)$/,
exclude: /node_modules/,
loader: require.resolve('babel-loader'),
},
{
test: /\.(png|svg|jpg|gif)$/,
include: [
path.resolve(__dirname, 'src/assets/'),
],
use: [
'file-loader'
],
},
{
test: /\.hbs$/,
loader: require.resolve('handlebars-loader'),
query: {
inlineRequires: '/assets/',
},
},
{
test: /\.scss$/,
use: [
{
loader: require.resolve('file-loader'),
options: {
name: 'main.css',
}
},
require.resolve('extract-loader'),
require.resolve('css-loader'),
require.resolve('postcss-loader'),
require.resolve('sass-loader'),
],
}
]
},
I am working on a large codebase; I have multiple src files to compile. When I run watch or compile for production it will compile all files found in src. Which is exactly what webpack should do.
But I would like to compile only the files which have been recently changed instead of all the files. Is this possible?
Here's my webpack config
