I am trying to create my react application from scratch but my webpack.config.js is giving me errors saying [webpack CLI ] failed to load
Below is the webpack.config.js code
const HtmlWebPackPlugin = require(“html-webpack-plugin”);
const htmlPlugin = new HtmlWebPackPlugin({
template: “./src/index.html”,
filename: “./index.html”
});
module.exports = {
mode: ‘development’,
module: {
rules: [{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: “babel-loader”
}
},
{
test: /\.css$/,
use: [“style-loader”, “css-loader”]
}
]},
plugins: [htmlPlugin]
};
Above is the code giving me errors in the webpack.config.js

I have an express server that is written in es5 and es6 combined. It consists of js and ts files. So now when I make a webpack build and start the server, it runs fine. But if my code throws an error then the error tracing is not correct i.e source of error (file, line and column number) is not showing correctly.
Is there a way to map the bundle with the source?
I have tried adding:
devTool: "source-map" to webpack config but it doesn't work, it seems to be working with the browser. Is there any way to achieve the same for server-side as well?
Here is my webpack.config.js
const nodeExternals = require("webpack-node-externals");
const webpack = require("webpack");
const path = require("path");
module.exports = {
stats: "detailed",
target: "node",
externals: [nodeExternals()],
entry: {
app: "./server.js",
backupCronApp: "./backup/cron/index.js"
},
output: {
path: path.join(__dirname, "/build"),
filename: "[name].js",
libraryTarget: "commonjs2",
},
plugins: [new webpack.EnvironmentPlugin(["NODE_ENV"])],
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: "babel-loader",
},
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/,
},
],
},
resolve: {
extensions: ['.ts', '.js'],
},
};
Entry file will build literally just fine, but the error occurs on client side, which makes the whole bundle file doesn't work with this issue Uncaught TypeError: Cannot read property 'Blob' of undefined
and i have attached the webpack.config.js which i have tried too
const path = require('path')
const webpack = require('webpack')
const HtmlPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const config = {
entry: './src/main-entry.js',
output: {
path: path.resolve(__dirname, 'views/dist'),
filename: 'bundle.js'
},
module: {
rules: [
{ test: /\.(png|woff|woff2|eot|ttf|svg|gif)$/, loader: 'url-loader?limit=100000' },
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
use: 'css-loader', fallback: 'style-loader'
})
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
}
]
},
plugins: [
new ExtractTextPlugin('bundle.css'),
new webpack.optimize.UglifyJsPlugin({
include: /\.min\.js$/,
minimize: true
})
]
}
module.exports = config
I am using webpack latest version. But i don't know why this is happening? can you help me?
I bundled my node application with webpack2, I used JQuery with jade for my frontend. while run my application I am getting this error,
node_modules\jquery\dist\jquery.js:31
throw new Error( "jQuery requires a window with a document" );
^
Error: jQuery requires a window with a document
i used
var $ = require("jquery");
in all frontend javascript files.
I tried with this these solutions,
this to ,
{
test: require.resolve('jquery'),
loader: 'expose?$!expose?jQuery'
},
how I can handle this problem?
webpack.config.js
var path = require('path');
var nodeExternals = require('webpack-node-externals');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
target: 'node',
entry: {
app: ['babel-polyfill', './bin/run.js'],
},
output: {
path: './build',
filename: '[name].min.js'
},
externals: [nodeExternals()],
plugins: [
new HtmlWebpackPlugin()
],
module: {
rules: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /lodash/
},
{
test: /\.jade$/,
loader: 'jade-loader'
},
{
test: /\.css$/,
use: [
{loader: 'style-loader'},
{
loader: 'css-loader',
options: {
modules: true
}
}
]
},
],
noParse: [/ws/]
}
};
jQuery is to be used on the frontend (browser) only.
It looks like you are trying to use it in Node itself to reference back to $.
It's important to note that jQuery does not support server side rendering.
-> var $ = require("jquery"); won't work..
I'm working on an Electron app which requires the code highlighting feature. I installed highlight module as a node dependency and use webpack to bundle all the code into the app.bundle.js.
However, when I launch the Electron app, I notice an error from the highlight module complaining
Uncaught Error: ENOENT: no such file or directory, scandir '//vendor/highlight.js/languages/'
Inside app.bundle.js, the highlight module still uses the vendor/highlight.js/languages/ to search for its utilities files which I thought should be included into app.bundle.js with their paths updated.
var Highlight = module.exports
, fs = __webpack_require__(336)
, hljs = __webpack_require__(408).hljs
, langRelPath = "vendor/highlight.js/languages/"
, langPath = __dirname + "/" + langRelPath
, reEndsWithJs = /\.js$/i
, loadedMap = {}
, availableMap = {}
;
It's my first time to use webpack, so it might be caused by some webpack misconfigurations. I paste the webpack.config.js for your convenience.
'use strict'
const path = require('path');
const webpack = require('webpack');
module.exports = {
entry: [
'./app/app.js'
],
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'app.bundle.js'
},
module: {
loaders: [{
test: /\.js$/,
include: [path.resolve(__dirname, 'app')],
exclude: /node_modules/,
loaders: ['babel?presets[]=es2015,presets[]=react']
}, {
test: /\.(scss|css)$/,
loaders: ['style', 'css', 'sass']
}, {
test: /\.json/,
loader: 'json'
}, {
test: /\.(png|jpg)$/,
loader: 'url-loader'
}, {
test: /\.html$/,
loader: 'html'
}, {
test: /\.txt$/,
loader: 'text'
}]
},
target: 'electron'
};
Does anyone have some idea for this?
（Everything works fine when not bundle by webpack.）
Thank you in advance:)
I am currently using the following webpack.config.js:
var webpack = require('webpack');
module.exports = {
entry: __dirname + "/src/index.js",
output: {
path: __dirname,
filename: "index.js"
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel',
exclude: '/node_modules/',
query: {
presets: ['latest']
}
}
]
},
plugins: [ new webpack.optimize.UglifyJsPlugin({minimize: true}) ]
}
This works exactly how I want it to. But now I want to add some comments with project info to the output file, on top of the one line with uglified code. How do I do this?
Add the comments to the code after minification using Webpack's BannerPlugin():
const webpack = require('webpack');
new webpack.BannerPlugin(banner);
// or
new webpack.BannerPlugin(options);
