Webpack multiple entries under certain urls

Hey I have this project which has this structure:
bundler -> webpack.common.js
src -> main.js, index.html, styles.css
package.json
node_modules... the rest doesnt matter really
It is set up like when I do: npm run dev webpack creates a live server using my current main.js for my index.html
The webpack.common.js looks like this:
const CopyWebpackPlugin = require("copy-webpack-plugin");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCSSExtractPlugin = require("mini-css-extract-plugin");
const path = require("path");
module.exports = {
entry: path.resolve(__dirname, "../src/current_script.js"),
output: {
hashFunction: "xxhash64",
filename: "bundle.[contenthash].js",
path: path.resolve(__dirname, "../dist"),
},
devtool: "source-map",
plugins: [
new CopyWebpackPlugin({
patterns: [{ from: path.resolve(__dirname, "../static") }],
}),
new HtmlWebpackPlugin({
template: path.resolve(__dirname, "../src/index.html"),
minify: true,
}),
new MiniCSSExtractPlugin(),
],
module: {
rules: [
// HTML
{
test: /\.(html)$/,
use: ["html-loader"],
},
// JS
{
test: /\.js$/,
exclude: /node_modules/,
use: ["babel-loader"],
},
// CSS
{
test: /\.css$/,
use: [MiniCSSExtractPlugin.loader, "css-loader"],
},
// Images
{
test: /\.(jpg|png|gif|svg)$/,
type: "asset/resource",
generator: {
filename: "assets/images/[hash][ext]",
},
},
// Fonts
{
test: /\.(ttf|eot|woff|woff2)$/,
type: "asset/resource",
generator: {
filename: "assets/fonts/[hash][ext]",
},
},
],
},
};
```
Now my question is how can I define multiple entries under certain URLs.
So for example now under localhost/ it will redirect me to index.html using my main.js
Is there a way of having localhost/2 use my index.html with another js file like main2.js

Webpack 5 - Scss relative urls won't load images

I have my scss and my images in folders at the same level.
File structure
styles
app.scss
images
my-image.jpg
Am trying to import my image like so
app.scss
body {
background: url(../images/my-image.jpg);
}
I have a simple webpack configuration to load scss and images.
webpack.config.js
const path = require("path");
module.exports = {
entry: "./resources/index.js",
resolve: {
alias: {
resource: path.resolve(__dirname, "resources/images"),
},
},
output: {
path: path.resolve(__dirname, "dist"),
publicPath: "/dist",
filename: "main.js",
assetModuleFilename: "[name][ext][query]",
clean: true,
},
mode: "production",
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
},
},
{
test: /\.scss$/,
use: ["style-loader", "css-loader", "sass-loader"],
},
{
test: /\.(png|jpg)/,
type: "asset",
},
],
},
};
Later on I tried to use resolve-url-loader between css-loader and scss-loader which seemed promising. But also to no avail.
The build isn't throwing any errors. But the page doesn't open the image.
Thank you for any help you give me my bros and bronettes.

At the end the problem with the images was simply in the publicPath on the web.config.js file.
Changing it from dist/ to /dist did the job.
const path = require("path");
module.exports = {
...
output: {
path: path.resolve(__dirname, "dist"),
publicPath: "dist/", //This is where the issue was
filename: "main.js",
assetModuleFilename: "[name][ext][query]",
clean: true,
},
...
};
Let this be a warning for all ye who enter webpack.

Webpack and Phaser 3 configuration

I'm trying to create a game using phaser 3 from a book tutorial and I decided to include webpack for learning purposes. I'm just in the initial stage of the game creation but when I ran the npm start script I got many errors that I fixed one by one. I don't have more errors but when running the scrip I got a blank page and nothing in being created in my dist folder. This is my webpack.config.js file content:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const webpack = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
module.exports = {
// https://webpack.js.org/concepts/entry-points/#multi-page-application
entry: ['babel-polyfill', './src/index.js'],
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
// https://webpack.js.org/configuration/dev-server/
devServer: {
contentBase: './dist',
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
include: path.resolve(__dirname, 'src/'),
use: {
loader: 'babel-loader',
options: {
presets: ['#babel/preset-env'],
},
},
},
{
test: /\.css$/i,
use: [
'style-loader',
'css-loader',
],
},
{
test: /\.(png|svg|jpg|gif)$/,
use: [
'file-loader',
],
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: [
'file-loader',
],
},
],
},
// https://webpack.js.org/concepts/plugins/
plugins: [
new CleanWebpackPlugin(),
new CopyWebpackPlugin({
patterns: [
{
from: path.resolve(__dirname, 'src/assets', '**', '*'),
to: path.resolve(__dirname, 'dist'),
},
],
}),
new HtmlWebpackPlugin({
filename: 'index.html',
template: './src/index.html',
}),
new webpack.DefinePlugin({
'typeof CANVAS_RENDERER': JSON.stringify(true),
'typeof WEBGL_RENDERER': JSON.stringify(true),
}),
],
};
And the rest of the files are located in my repo, feel free to check it out. Thank you in advance for any assistance.

change line in CopyWebpackPlugin
from from: path.resolve(__dirname, 'src/assets', '**', '*'),
to from: 'src/assets',
then npm run build

I solve the problem by creating a base and prod webpack files for better code readability and also importing every image that I need for the game in every scene. The most challenging part was the prod.js file because I was able to render images using npm start but not npm run build.

Unable to load styles using MiniCssExtractPlugin in Webpack 4 for Wordpress

I'm using Webpack 4 for Wordpress theme development. I have configured my webpack.config.js to extract css from js files and load them in separate files. But the styles are not getting loaded, either as or as separate css file.
webpack.config.js
const path = require("path");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
context: __dirname,
entry: {
userSide: "./js/public.js",
adminSide: "./js/admin.js"
},
output: {
path: path.resolve(__dirname, "dist"),
filename: "[name].js"
},
mode: "development",
devtool: "source-map",
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel-loader"
},
{
test: /\.(png|svg|jpg|jpeg|gif)$/,
use: [
{
loader: "file-loader",
options: {
outputPath: "dist/images",
name: "[name].[ext]"
}
}
]
},
{
test: /\.s?css$/,
use: [MiniCssExtractPlugin.loader, "css-loader", "sass-loader"]
}
]
},
plugins: [
new MiniCssExtractPlugin({
filename: "[name].[contenthash].css"
})
]
};
The css files are being created in the local directory whenever I run npm run dev but not showing changes in the website.
Please help

This is how I config my webpack
You can use my setting to see if it work for you
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
Add to plugins section:
plugins: [
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename: "[id].css"
}),
And rules section
{
"test":"/\\.scss$/",
"use":[
"style-loader",
"MiniCssExtractPlugin.loader",
{
"loader":"css-loader",
"options":{
"minimize":true,
"sourceMap":true
}
},
{
"loader":"sass-loader"
}
]
},
Also you may need to inject css to your html using HTML Webpack plugin

Deployment Problem with Webpack & Github Pages

I've got a little API App built with Webpack. To publish it on GitHub Pages I've installed the npm package gh-pages.
Everything works fine, the dist-folder is pushed correctly and when I open the live-version the index and scss files are displayed as well.
The problem now is that my bundle.js doesn't load. So the whole functionality is not active. Another thing I've discovered is that my media queries doesn't pop in as well.
Would be great if anyone could help me fixing that issue!
