Install with npm:
npm install --save-dev webpack
Install with yarn:
yarn add webpack --dev
- Bundles ES Modules, CommonJS, and AMD modules (even combined).
- Can create a single bundle or multiple chunks that are asynchronously loaded at runtime (to reduce initial loading time).
- Dependencies are resolved during compilation, reducing the runtime size.
- Highly modular plugin system to do whatever else your application requires.
webpack supports all browsers that are ES5-compliant (IE8 and below are not supported). webpack also needs
require.ensure(). If you want to support older browsers, you will need to load a polyfill before using these expressions.
webpack has a rich plugin interface. Most of the features within webpack itself use this plugin interface. This makes webpack very flexible.
Name Status Install Size Description mini-css-extract-plugin Extracts CSS into separate files. It creates a CSS file per JS file which contains CSS. compression-webpack-plugin Prepares compressed versions of assets to serve them with Content-Encoding i18n-webpack-plugin Adds i18n support to your bundles html-webpack-plugin Simplifies creation of HTML files (
index.html) to serve your bundles
extract-text-webpack-plugin Extract text from a bundle, or bundles, into a separate file
Loaders are activated by using
require()statements, or are automatically applied via regex from your webpack configuration.

webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.
webpack supports ES2015+, CommonJS and AMD modules out of the box. It performs clever static analysis on the AST of your code. It even has an evaluation engine to evaluate simple expressions. This allows you to support most existing libraries out of the box.
webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.
We want contributing to webpack to be fun, enjoyable, and educational for anyone, and everyone. We have a vibrant ecosystem that spans beyond this single repo. We welcome you to check out any of the repositories in our organization or webpack-contrib organization which houses all of our loaders and plugins.
Contributions go far beyond pull requests and commits. Although we love giving you the opportunity to put your stamp on webpack, we also are thrilled to receive a variety of other contributions including:
- Documentation updates, enhancements, designs, or bugfixes
- Spelling or grammar fixes
- README.md corrections or redesigns
- Adding unit, or functional tests
- Triaging GitHub issues -- especially determining whether an issue still persists or is reproducible.
- Searching #webpack on twitter and helping someone else who needs help
- Teaching others how to contribute to one of the many webpack's repos!
- Blogging, speaking about, or creating tutorials about one of webpack's many features.
- Helping others in our webpack gitter channel.
If you are worried or don't know where to start, you can always reach out to Sean Larkin (@TheLarkInn) on Twitter or simply submit an issue and a maintainer can help give you guidance!
Looking to speak about webpack? We'd love to review your talk abstract/CFP! You can email it to webpack [at] opencollective [dot] com and we can give pointers or tips!!!
Creating your own plugins and loaders
If you create a loader or plugin, we would <3 for you to open source it, and put it on npm. We follow the
We consider webpack to be a low-level tool used not only individually but also layered beneath other awesome tools. Because of its flexibility, webpack isn't always the easiest entry-level solution, however we do believe it is the most powerful. That said, we're always looking for ways improve and simplify the tool without compromising functionality. If you have any ideas on ways to accomplish this, we're all ears!
If you're just getting started, take a look at our new docs and concepts page. This has a high level overview that is great for beginners!!
Looking for webpack 1 docs? Please check out the old wiki, but note that this deprecated version is no longer supported.
If you want to discuss something or just need help, here is our Gitter room where there are always individuals looking to help out!
If you are still having difficulty, we would love for you to post a question to StackOverflow with the webpack tag. It is much easier to answer questions that include your webpack.config.js and relevant files! So if you can provide them, we'd be extremely grateful (and more likely to help you find the answer!)
If you are twitter savvy you can tweet #webpack with your question and someone should be able to reach out and help also.
If you have discovered a 🐜 or have a feature suggestion, feel free to create an issue on Github.

Founder of the core team
Most of the core team members, webpack contributors and contributors in the ecosystem do this open source work in their free time. If you use webpack for a serious task, and you'd like us to invest more time on it, please donate. This project increases your income/productivity too. It makes development and applications faster and it reduces the required bandwidth.
This is how we use the donations:
- Allow the core team to work on webpack
- Thank contributors if they invested a large amount of time in contributing
- Support projects in the ecosystem that are of great value for users
- Support projects that are voted most (work in progress)
- Infrastructure cost
- Fees for money handling
Other Backers and Sponsors
Before we started using OpenCollective, donations were made anonymously. Now that we have made the switch, we would like to acknowledge these sponsors (and the ones who continue to donate using OpenCollective). If we've missed someone, please send us a PR, and we'll add you to this list.

Special Thanks to
(In chronological order)
- @medikoo for modules-webmake, which is a similar project. webpack was born because I wanted Code Splitting for modules-webmake. Interestingly the Code Splitting issue is still open (thanks also to @Phoscur for the discussion).
- @substack for browserify, which is a similar project and source for many ideas.
- @jrburke for require.js, which is a similar project and source for many ideas.
- @defunctzombie for the browser-field spec, which makes modules available for node.js, browserify and webpack.
- Every early webpack user, which contributed to webpack by writing issues or PRs. You influenced the direction...
- @shama, @jhnns and @sokra for maintaining this project
- Everyone who has written a loader for webpack. You are the ecosystem...
- Everyone I forgot to mention here, but also influenced webpack.
