I checked the contents of both files and one is compressed by OptimizeCSSAssetsPlugin and the other is not.
I also want to ask why this css chunks doesn't have the brotli and gziped version.
Thanks

How i can solve the devServer problem in webpack?

I would be grateful for any help or advice. I have compiled the configuration of the webpack, everything works in production mode, but the webpack-dev-server does not see static files and gives the error "Cannot get /". How can I solve this problem? Thank you in advance for the answer. Here is my webpack.config.js
const path = require("path");
const { VueLoaderPlugin } = require("vue-loader");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");

}
return config;

Here is a project folders
According to the doc, you need to set the publicPath in the devServer.
Look at the documentation
module.exports = {
//...
devServer: {
static: {
directory: path.join(__dirname, 'public'),
},
compress: true,
port: 9000,
},
};

Webpack in watch mode takes too long to build (~23s) after changes

After saving changes, webpack takes on average ~23 seconds to build. This is the output while it is building. It goes all the way up to 6695 modules before completing.
18% building 915/944 modules 29 active ...terial-ui/icons/esm/WallpaperTwoTone.js
How do I speed up the build time? Any help would be greatly appreciated.

Script we use to start the build:
"hot_build": "npm run clean:static && webpack -w --mode development --config webpack.dev.js --progress"
I have a question why practically the dev version is the same as in the prod.
Only the prod version should contain MiniCssExtractPlugin.loader version dev style-loader.
dev
{
test: /\.(css|sass|scss)$/,
use: [
'style-loader',
{
loader: 'css-loader',
options: {
importLoaders: 2,
sourceMap: true
},
},
...
prod
{
test: /\.(css|sass|scss)$/,
use: [
MiniCssExtractPlugin.loader,
{
loader: 'css-loader',
options: {
sourceMap: true,
importLoaders: 2
},
},
...
The same happens with the optimization section, you should only use it in the prod version.
Next issue #babel/polyfill is deprecated. Delete #babel/polyfill and add core-js instead and configure .babelrc accordingly.
The biggest problem is that every change you delete the built folders and everything is copied again by 'CopyPlugin'. Isn't it better to use webpack-dev-server for this?
And rebuild everything so that webpack.dev.js uses this.
Then the first time it will take a long time to build up but the changes you will make later will be very quick.

Separate the config API with dev and prod webpack

Please tell me, here is the config.js file in it, the exported variable with a reference to the API, but there is an API for the dev version, and there is a separate API for the prod version, as I understand it, you need to make 2 separate files, but how to make it in webpack so that when dev he used one file, and prod another?
Below added webpack configuration files, a project on react.js (if that makes any difference :) )

You can define two different npm scripts and use the --config flag for custom files (/file-paths):
"build:dev": "webpack --config ./webpack.client.dev.js",
"build:prod": "webpack --config ./webpack.client.prod.js"
For the common you have to use webpack-merge, for example:
const merge = require('webpack-merge');
const common = require('./webpack.common.js');
module.exports = merge(common, {
mode: 'production',
...
});

Webpack - TypeError: callbacks[i] is not a function

When i bundle split my webpack vendor ( node_modules ) my main.js file prints out the following message. When i disable bundle splitting, it works. But when I bundle split and i console.log the module (responsiveMenu) It complains about callbacks. I'm using the webpack bundle-loader to create my code splitted bundle.
my dist folder ususlly ends up like the following
main.js
bundle.1.js
bundle.2.js
bundle.x.js etc
below is my webpack file, the top of main.js and responsiveMenu.js, my babelrc.js is also present
babelrc.js
api.cache(true);

EventSource's response has a MIME type ("text/html") that is not "text/event-stream". Aborting the connection

I've read a lot about this error, and I can't find the solution.
hot reloading is not working, and I have an error:
EventSource's response has a MIME type ("text/html") that is not
"text/event-stream". Aborting the connection.
"webpack": "^2.5.1",
"webpack-dev-middleware": "^1.8.4",
"webpack-hot-middleware": "^2.22.1",
I've found https://github.com/webpack-contrib/webpack-hot-middleware/issues/26 this but it didn't help me
Do you have any idea how to get rid of this error?
