I can't understand the major things on the .pack files? does it takes more file sizes and got heavy things up. I am delivering https://www.theresearchguardian.com/services/thesis/mphil-thesis-help/ to the students of Mphil and Master who eagerly need for it.

I'm using module federation and promised based dynamic remotes (https://webpack.js.org/concepts/module-federation/#promise-based-dynamic-remotes). Everything is working as I'd like, except I'm seeing the output of my promise function in the build output. Is there any way to suppress that?

Here's partial webpack build output, after using the sample promised based dynamic remote in the docs.

Hi y’all, I have an AngularJS application being built with webpack and then being served by an IIS app Pool, I’m upgrading it to angular 14 with a hybrid approach (angular/angularjs), I’m using @ngtools/webpack to compile ts files, but I’m getting this after webpack’s build, any ideas?

    if (progressData && progressData.completed > progress) {
      setProgess(() => progressData.completed);

Hello. I get this error when trying to compile:

Conflict: Multiple chunks emit assets to the same filename static/js/bundle.js (chunks main and runtime)

Here's my config:

I need to know why this happens and how to fix it.

That problem seems to be solved by using fullhash in filename. However another problem has been found:
Failed to compile.

Module not found: Error: You attempted to import /home/farooqkz/playground/chooj/node_modules/babel-preset-inferno-app/node_modules/@babel/runtime/helpers/esm/classCallCheck which falls outside of the project src/ directory. Relative imports outside of src/ are not supported.
You can either move it inside src/, or add a symlink to it from project's node_modules/.

I think that has been solved, too. Now the problem is:

Failed to compile.

Error: [BABEL] /home/farooqkz/playground/chooj/src/index.js: Unknown option: .config. Check out https://babeljs.io/docs/en/babel-core/#options for more information about options.

Is it related to webpack? or perhaps I must ask in babel community?


I have issue when use style-loader with experiments.lazyCompilation

import '/style/a.css'
import '/style/b.css'

npm script : webpack --mode development

Normal Case (turn off experiments.lazyCompilation)

Both styles are inserted on page (That OK)

LazyCompilation Case (turn on experiments.lazyCompilation)

  • Just style of "b.css" is inserted
  • Let use styleTagTransform of style-loader to test progress
    (css, style) { 
    if(!window.prevStyle) {window.prevStyle = style} 
    else if(window.prevStyle === style) {
      console.log('current style tag is same prev style tag!')
    style.innerHTML = `${css}` 
    then I figure out that the style element created in style-loader for both .css files is same (notice that I use injectType: "style tag" not singletonStyleTag), And after I reloaded the page (after first lazy compile) both style worked right -> When I use experiments.lazyCompilation with import 2 styles or more, I must reload the page after first lazy compile to work right

Hi all, I have a quick question on module federation I hope you can help with.

When are modules loaded? Is it done on server side when the makes a request to the site and the whole bundle is pulled down or is the "host" bundle received by the browser and then the modules are fetched? Just trying to determine how many round trips to the server are done.

Hi, hoping for some advice. I added a dependency (serialize-error) to a Webpack 5 project, and the build now fails:

ERROR in serviceWorker.js from Terser plugin
Minimizer doesn't return result

It's proving complex to try and extract a minimal reproducible example, but I can work on that. In the meantime, can anyone recommend how I might diagnose this further? There's not much to be found by Googling the error. Is it possible to get the minimizer to emit error / logging information?

Hey, I just updated a project I am working on and an underlying webpack.config.js got its scriptType changed from 'text/javascript' to 'module'. This appears to have broken web-workers using import.meta.url as I now get Cannot use 'import.meta' outside a module when trying to create a web worker using the recommended webpack 5 syntax... anyone have any idea?
export const worker = new Worker(new URL('./worker.ts', import.meta.url)); <-- this is how the webpack docs say to use workers, and this was working fine until my webpack config got changed as stated

I'm trying to build an ESM package, and I understand that in theory imports within the package should use .js, but I'm wondering how react-bootstrap gets away without that, because they have an ESM package and the files in there don't use imports with the extensions
Evan Raffel
I think the answer is that react-bootstrap didn't build an ESM package, they built a CJS package and put it in a folder named ESM. nvm

Hi! Can't save generated images in folders relevant to they width with Webpack Imagemin plugin. Trying to generate images to different sizes and formats. Something like this:

    media="(min-width: 576px)"
    media="(min-width: 960px)"
    media="(min-width: 576px)"
    media="(min-width: 960px)"
  <img src=".src/img/slide.jpg" alt="slideer image" />

Images should saved in folders relevant to they width. E.g:

I try to use filename option in plugin settings

const path = require("path");
const ImageMinimizerPlugin = require("image-minimizer-webpack-plugin");

module.exports = {
  entry: {
    index: "./src/index.ts",
  mode: "development",
  output: {
    filename: "js/[name].js",
    path: path.resolve(__dirname, "dist"),
    clean: true,
    pathinfo: true,
  module: {
    rules: [
        test: /\.html$/i,
        use: "html-loader",
        test: /\.(jpe?g|png|gif|svg)$/i,
        type: "asset/resource",
        parser: {
          dataUrlCondition: {
            maxSize: 10 * 1024, // 10kb
        // If i don't use this generator option, images saved in root (dist) folder -> dist/6gj86ddgt36jjy78.jpg
        generator: {
          filename: "example/[name]-[hash][ext]",

  optimization: {
    minimize: true,
    minimizer: [
      new ImageMinimizerPlugin({
        minimizer: {
          // Using this option (with filename: in loader above) saves as -> dist/example/generated-slide-540-6gj86ddgt36jjy78.webp
          // --- images/[width] is ignored and folder name comes from loader options
          filename: "images/[width]/generated-[name]-[width][ext]",
          implementation: ImageMinimizerPlugin.sharpMinify,

          options: {
            encodeOptions: {
              // ....
        generator: [
            // Adding this option not worked too..
            // ---
            // filename: "images/[width]/generated-[name]-[width][ext]",
            preset: "webp",
            implementation: ImageMinimizerPlugin.sharpGenerate,
            options: {
              encodeOptions: {
                webp: {
                  // ....

What i am doing wrong?

P.S. I don't wont to use Imagemin plugin as Standalone loader because plugin docs

Hi everyone , what's the difference between <a href="/html/default.asp">HTML tutorial</a> and <a href="html/default.asp">HTML tutorial</a>

This is repository with my Angular frontend (part of full frontent with error) https://github.com/Alex-1557/ErrorModuleParseFailed

Do any webpack devs hang out in here? Trying to reason about the safety of force resolving webpack-sources to 3.2.3 for webpack v4. As far as I can tell its API compatible, aside from the removal of LineToLineMappedSource
The time savings I see in our build is profound and a v5 upgrade is in the works but it will take a bit. It's mostly from the removal of @mozilla/source-map

Вадим Бударин

I have a babel plugin which inserts import of helpers
After building the project using webpack with babel-loader, there are several original require instructions left in the code

const { something } = require('/path-to-a-module')

What to do?

Вадим Бударин

some of the imports are normally translated into calls

const { aHelper: _h } = __webpack_require__(1930),

and the part remained in the original

Hi, I'm trying to use lazyCompilation and I'm getting cors errors. I see this PR was merged webpack/webpack#15121 recently. Wondering if there's a way to access a nightly version of webpack or something like that so I can check and see if this fix works for me. Any tips?
Luciano Graziani

Conceptual question here: does webpack interprets each module export as an atomic identity, isolated from other exports, or the module IS the atomic element?
I have this situation:

  • Module A exports 3 functions: X, Y and Z. X is a pure function, and doesn't use any import, but Y and Z are not pure, and they have lot of complexity and imports that make the module enormous.
  • Module B imports X (entrypoint nº1)
  • Module C imports Y (entrypoint nº2)
  • Module D imports Z (entrypoint nº3)

To webpack, this means that module A doesn't have deadcode, so it won't remove anything, but the question is: entry point nº1 will have the entire module A in its chunk and that's OK and expected, right?

Hi guys, I am having issues migrating legacy js files that uses a global declaration (non esModules) into webpack flow. I have managed to bundle all js in the folders and minify, but the global object declaration that the different files were calling seems to be now out of scope. I have looked into shimming but I am not sure if that is the right way to access this global variable for each file. (It is in plan to make the company move to esm eventually but legacy support should be maintained). Any help or article on the topic please.

I'm trying to add an SSL certificate to my web server. I did it the recommended way. I used a self-signed certificate AND I tried using a certificate from CloudFlare and Let's Encrypted. What happens is that my page doesn't load. I get an error saying that no data was returned. I'm using a webpack config file and I used the https property.

https: {
cert: fs.readFileSync('/etc/letsencrypt/live/mysite/fullchain.pem'),
key: fs.readFileSync('/etc/letsencrypt/live/mysite/privkey.pem')

The paths provided are what Let's Encrypt gave me. I start the server and try to connect and I get something like ERR_EMPTY_RESPONSE from Chrome.

I also tried using an origin certificate from Cloudflare. Same thing.

I made sure my server has the right ports open, that I'm using the right address. I have no clue what's wrong.

Any suggestions?

Hello, I wanted to thank you for sharing this useful material. What is more, some of the tips that are provided here are really great. They will be useful for those who are not so good at programming and coding, like me as an example. From my point of view, I could help you in resume writing.

Hello guys.

I am looking for a way to to easily refer HTML modules from within my index.html page. Is that possible using webpack?

For example,

I want to write in my index.html file the following,


where header, banner, services etc. are separate html files .

Is this possible to be done using webpack?

I ve looked at Html loader and Webpack Html plugin, but it does not seem I can use these to achieve what I want.

Can someone help?

I just upgraded a working CRA project, and got: BREAKING CHANGE: The request 'react-bootstrap/Table' failed to resolve only because it was resolved as fully specified
The thing is, this isn't a .js or .mjs file, it's a separate package.json coming from node_modules. How the heck do I massage import Table from "react-bootstrap/Table"; so webpack will be happy?
