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.

How to dynamically load an asset (pdf) in an angular app using webpack?

I am trying to load a pdf into my angular app running on webpack dev server using HTML <object> tag with data attribute.
Since the pdf path is generated at run time and is absolute like C:\test.pdf.
It is not loaded into the UI but rather console logs the error -
Not allowed to load local resource: file:///C:/test.jpeg
However the production build of the app which doesn't run on hosting server but as static html works fine. Also, relative path works fine as well.
How can i load the pdf ?

}
]},
plugins: [
new webpack.optimize.CommonsChunkPlugin({

}),
new HtmlWebpackPlugin({
template: 'src/index.html'
}),
new webpack.ContextReplacementPlugin(
/angular(\\|\/)core(\\|\/)#angular/,
path.resolve(__dirname, '../src')
)
]
};
webpack.dev.js
var webpackMerge = require('webpack-merge');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var commonConfig = require('./webpack.common.js');
const path = require('path');
const rootDir = path.resolve(__dirname, '..');
commonConfig.entry = {
'polyfills': './src/polyfills.ts',
'vendor': './src/vendor.ts',
'app': './src/main.ts'
};
commonConfig.module.rules.unshift({
test: /\.ts$/,
loaders: ['awesome-typescript-loader', 'angular2-template-loader', 'angular-router-loader']
});
module.exports = webpackMerge(commonConfig, {
devtool: 'cheap-module-eval-source-map',
output: {
path: path.resolve(rootDir, 'dist'),
publicPath: 'http://localhost:8080/',
filename: '[name].js',
chunkFilename: '[name].chunk.js'
},
plugins: [
new ExtractTextPlugin('[name].css')
],
devServer: {
historyApiFallback: true,
stats: 'minimal'
}
});

You could tell the devServer from where to serve files.
devServer: {
historyApiFallback: true,
stats: 'minimal',
contentBase: ['./dist', 'C:\\']
}
Then you can load your file with <... src="/file_name.ext" ... />
But I would not recommend adding C:\ as contentBase. If you have the possiblity, define another output directory for your generated PDF.

Webpack2: require is not defined

I get this error in app.js:
Uncaught ReferenceError: require is not defined
Why webpack require not work? Is any additional wabpack configutarion needed to make this work?

Make Webpack render in a file other than an index

By default Webpack looks for a specific index.html file in a specified directory, right? What I want to know is can I tell webpack to look for and inject my bundled files in a file that I specify?
I ask this because I'm trying to develop a Ghost theme with webpack and by default, a Ghost theme looks for a default.hbs file to serve as an index file.
I tried to use the HtmlWebpackPlugin to set the filename for entry all while making the same file for web pack's output, but it's not working.
This is my current webpack.dev.config.js:
var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
entry: [
'webpack-dev-server/client?http://localhost:2368',
'webpack/hot/only-dev-server',
'./src/router'
],
devtool: 'eval',
debug: true,
output: {
path: path.join(__dirname, 'build'),
filename: 'bundle.js',
publicPath: '/static/'
},
resolveLoader: {
modulesDirectories: ['node_modules']
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin(),
new HtmlWebpackPlugin({
hash: true,
filename: 'default.hbs',
template: __dirname + '/public/default.hbs',
})
],
resolve: {
extensions: ['', '.js', '.sass', '.css', '.hbs']
},
module: {
loaders: [
// js
{
test: /\.js$/,
exclude: /node_modules/,
loaders: ['babel'],
include: path.join(__dirname, 'src')
},
// CSS
{
test: /\.sass$/,
include: path.join(__dirname, 'src'),
loader: 'style-loader!css-loader!sass-loader'
},
// handlebars
{
test: /\.hbs$/,
include: path.join(__dirname, 'public'),
loader: 'handlebars-template-loader'
}
]
},
node: {
fs: 'empty'
}
};

Easiest way: you can configure webpack to use any file and template file via the html-webpack-plugin plugin. You can also specify the element to inject into.
import HtmlWebpackPlugin from 'html-webpack-plugin';
[...]
const plugins = [
new HtmlWebpackPlugin({
template: 'templates/myTemplateFile.tpl.html',
inject: 'body',
filename: 'myOutputFile.html'
})
];

Webpack resolve alias works with sass but not when importing javascript

I get this error when importing a React component with an alias:
ERROR in ./src/components/EventsFeed/EventsFeedItem/ItemFooter/ItemFooter.js
Module not found: Error: Cannot resolve module '~components/LikeButton' in /Applications/MAMP/htdocs/react-feed/src/components/EventsFeed/EventsFeedItem/ItemFooter
# ./src/components/EventsFeed/EventsFeedItem/ItemFooter/ItemFooter.js 15:18-51
My goal is to resolve the directories automatically so that I don't have to deal with something like this in every import: "../../../../...". I'm importing the component LikeButton like this:
import LikeButton from '~components/LikeButton';
It works when I import SASS inside style.scss files like this:
#import '~/stylesheets/utilities/settings';
Here's how my webpack.config.js file looks:
const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const autoprefixer = require('autoprefixer');
const sassLoader = 'css!sass!postcss?indentedSyntax=scss&includePaths[]=' + path.resolve(__dirname, './src');
module.exports = {
devtool: 'inline-source-map',
entry: [
'./src'
],
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js', // this exports the final .js file
publicPath: '/public'
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loaders: ['react-hot', 'babel?presets[]=react,presets[]=es2015,plugins[]=lodash']
},
{
test: /\.scss$/, loader: ExtractTextPlugin.extract('style', sassLoader)
}
]
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin(),
new ExtractTextPlugin("./bundle.css")
],
postcss: [
autoprefixer({
browsers: ['last 2 versions']
})
],
resolve: {
modulesDirectories: ['node_modules', 'src'],
extensions: ['', '.js', '.scss'],
root: [path.join(__dirname, './src')],
alias: {
stylesheets: path.join(__dirname, './src/stylesheets'),
components: path.join(__dirname, './src/components')
}
}
};
This is how my src folder looks like:
