I have been trying to deploy my production build with webpack but I can't get it done. I almost read and tried everything and can't make it work.

I tried changing the presets of babel. I don't know if it could be a problem with the library query-string but even when I don't use it the error persists.
I also tried almost all configurations from https://github.com/webpack-contrib/uglifyjs-webpack-plugin/issues/104 and can't make it work :C....
I hope someone can help me I have been fighting with this error since weekend and im near to kill myself T_T
Already tried babel-polyfill and dont work :(
Just updated to webpack 4 and solved my problem. To many people have this kind of error with webpack < 4.
I will leave my webpack 4 configuration here for those who had suffered like me

In my experience, it's usually Uglify being too aggressive.
I noticed that in your answer, you've swapped out Uglify for compression-webpack-plugin. That's probably what made the bug go away.
In your original package.json, I'd change the Uglify config to
new UglifyJsPlugin({
sourceMap:true,
cache: true,
parallel: true,
uglifyOptions:{
ecma:8
}
}),
First, you want to see Uglify's warnings. It'll tell you if there's code that's likely to get clobbered by the minification / obfuscation algorithm. If there are, you may have to play with the compress, mangle, toplevel or keep_fnames options depending on how your code is structured. https://github.com/mishoo/UglifyJS2#minify-options
I understand that this might show a lot of warnings from 3rd party libraries. There's a couple things you can do:
Find alternative libs that minify correctly (they'll probably be higher quality anyways).
Import the already minified versions of the lib from /dist instead of from /src and then exclude the lib from the Uglify plugin
The settings for cache and parallel just make the minification run a bit faster.
Sometimes such a problem may be a result of the non-transpiled packages (excluded from transpiling).
To solve this you should include these packages to transpiled code:
rules: [
...
test: /\.jsx?$/,
exclude(resource) {
return (
/node_modules/.test(resource)
&& !/node_modules\/(query-string|strict-uri-encode|split-on-first)/.test(resource)
);
},
...
]
I'm currently using Webpack 3.10.0 along with following babel packages.
"babel": "^6.23.0",
"babel-core": "^6.26.0",

"babel-polyfill": "^6.26.0",
"babel-preset-es2015": "~6.13.2",
"babel-preset-react": "~6.11.1",
My issue is, during runtime I get the following error on the browser console and the page doesn't load.

I have imported babel-polyfill into Main.js and MainInt.js files as instructed in https://babeljs.io/docs/usage/polyfill/ and I haven't used new webpack.optimize.ModuleConcatenationPlugin().
Any ideas on how to resolve this issue. Thanks in advance :)
I found the issue. Thank you everyone for your help.
Giving the full path in filename fixed the issue.
output: {
path: path.resolve(__dirname, '../assets/myproject'),
filename: '../assets/myproject/[name].js',
},
I have a problems with souce maps. They are generated but apparently not used.
I use webpack-dev-server, react hot module replacement and Webpack v3.x if that is important.
Inside of my webpack-config i use devtool: 'source-map' and I run my script like this:
"webpack": "cross-env NODE_ENV=development webpack-dev-server -d --config webpack.config.js"
Example of error that I get
When I click on this client?e36c:157 it doesn't take me to source code but:
If I remove devtools from webpack.config and -d tag from script I get the same output

I've read multiple threads regarding similar issues and tried some propositions, but had no results.
I've followed few tutorials related to React.js and WebPack 3. As the result the application is working well on all browsers (at this moment) except IE 10 and below. The error points to bundle.js (once I'm using the configuration Nr.1):
SCRIPT1002: Syntax error and the line - const url = __webpack_require__(83);
With configuration Nr2., on local server - : SCRIPT1002: Syntax error - line with eval()
And the same configuration, but running on remote server produces a bit different error:
SCRIPT5009: 'Set' is undefine

Here additionally I've added the es2015 to presets: ['env', 'react', 'es2015'] and plugins: ["transform-es2015-arrow-functions"] but it made no sense.
Well in case when the babel loader won't work at all of misconfiguration or something else, I think that the whole application won't start. I believe that something should be done with presets or their order... Need advice from experienced developer
UPDATE
I've changed devtool to inline-cheap-module-source-map and got error point to overlay.js -> const ansiHTML = require('ansi-html');
In your package.json file
change the version of webpack-dev-server to version "2.7.1" (or earlier).
"webpack-dev-server": "2.7.1"
Then do a npm install et voilĂ .
That solved the problem for me.
All versions after 2.7.1 gives me an error similar to yours.
Simply add devtools : "source-map" to your Webpack config like this:
const path = require('path');
module.exports = {
devtool: "source-map",
entry: ['babel-polyfill', path.resolve(__dirname, './js/main.js')],
mode: 'production',
output: {
path: __dirname+'/js/',
filename: 'main-webpack.js'
}
};
This will remove eval and change your source map to be supported by IE.
UPDATE I've changed devtool to inline-cheap-module-source-map and got error point to overlay.js -> const ansiHTML = require('ansi-html');
And to support ES6 syntax you have to compile your JavaScript code with Babel.
I'm running into an interesting error with my react build. My configuration runs perfectly fine on my Mac, but I get the following error when running on my Windows 10 computer:
ERROR in ./~/react-toolbox/lib/app_bar/theme.css
Module parse failed: C:\cygwin64\home\username\projectname\node_modules\react-toolbox\lib\app_bar\theme.css Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
| :root {
| --palette-red-50: rgb(255, 235, 238 );
| --palette-red-100: rgb(255, 205, 210);

Here's my Webpack 2 Config
'use strict'
const webpack = require('webpack')
const path = require('path')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const postcssImport = require('postcss-import')
const postcssCssnext = require('postcss-cssnext')
// configure source and distribution folder paths
const publicFolder = 'public'
const buildFolder = 'build'
module.exports = {
entry: {
'app': [
'react-hot-loader/patch',
'./src/index.js'
]
},
resolve: {
//Allows us to leave off the file extension when importing
extensions: ['.js', '.json', '.jsx']
},
module: {
rules: [
{
enforce: 'pre',
test: /\.js$/,
exclude: '/node_modules/',
loader: 'eslint-loader',
},
{
test: /\.(js|jsx)$/,
exclude: '/node_modules/',
loader: 'babel-loader'
},
{
test: /\.css$/,
include: [
/(node_modules)\/react-toolbox/,
path.join(__dirname, 'src')
],
use: ExtractTextPlugin.extract({

use: [
{

options: {

}
},
{

options: {
sourceMap: 'inline',
plugins: function() {
return [
postcssImport({ addDependencyTo: webpack }),
postcssCssnext({
browsers: ['last 2 versions', '> 5%'],
compress: true,
})
]
},
},
}
]
})
}
]
},
plugins: [
new ExtractTextPlugin({

}),
new CopyWebpackPlugin([{

}]),
new CopyWebpackPlugin([{

}]),
new CopyWebpackPlugin([{
from: path.join(__dirname, publicFolder, 'demo.js'),
to: path.join(__dirname, buildFolder, 'demo.js')
}]),
new webpack.NamedModulesPlugin()
],
output: {

publicPath: '/',
//Proxies to match requests to our Django API endpoints
proxy: {
'/api': {
target: 'http://localhost:4000'
}
},
hot: true
}
}
And for good measure, here's my .babelrc config
{
"presets": [
[ "es2015", { "modules": false } ],
"latest",
"react"
],
"plugins": ["react-hot-loader/babel", "syntax-dynamic-import"],
"env": {
"test": {
"plugins": ["dynamic-import-node"]
}
}
}
No idea why the error occurs when compiling on Windows 10 but works perfectly on my Mac. I can't seem to find any current info regarding this issue for either PostCSS or Webpack 2.
Any ideas?
just remove
include: [
/(node_modules)\/react-toolbox/,
path.join(__dirname, 'src')
]
from test: /\.css$/ rule
