webpack
Webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

Install with yarn:

Introduction
Webpack is a bundler for modules. The main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.
TL;DR
* 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.
* Loaders can preprocess files while compiling, e.g. TypeScript to JavaScript, Handlebars strings to compiled functions, images to Base64, etc.
* Highly modular plugin system to do whatever else your application requires.

Get Started
Check out webpack's quick Get Started guide and the other guides.
Browser Compatibility
Webpack supports all browsers that are ES5-compliant (IE8 and below are not supported). Webpack also needs Promise for import() and require.ensure(). If you want to support older browsers, you will need to load a polyfill before using these expressions.
Concepts
Plugins
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
html-bundler-webpack-plugin Renders a template (EJS, Handlebars, Pug) with referenced source asset files into HTML.
html-webpack-plugin Simplifies creation of HTML files (index.html) to serve your bundles
pug-plugin Renders Pug files to HTML, extracts JS and CSS from sources specified directly in Pug.
Loaders
Webpack enables the use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.
Loaders are activated by using loadername! prefixes in require() statements, or are automatically applied via regex from your webpack configuration.
JSON
Name Status Install Size Description
Loads and transpiles a CSON file
Transpiling
Name Status Install Size Description

Performance
Webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.
Module Formats
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.
Code Splitting
Webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.
Optimizations
Webpack can do many optimizations to reduce the output size of your JavaScript by deduplicating frequently used modules, minifying, and giving you full control of what is loaded initially and what is loaded at runtime through code splitting. It can also make your code chunks cache friendly by using hashes.
Developer Tools
If you're working on webpack itself, or building advanced plugins or integrations, the tools below can help you explore internal mechanics, debug plugin life-cycles, and build custom tooling.
Instrumentation
Name Status Description
tapable-tracer Traces tapable hook execution in real-time and collects structured stack frames. Can export to UML for generating visualizations.
Contributing
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.
* The Contributor's Guide to webpack
To get started have a look at our documentation on contributing.
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 x-loader, x-webpack-plugin naming convention.
Support
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 to 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!!
If you have discovered a 🐜 or have a feature suggestion, feel free to create an issue on GitHub.

Maintenance
This webpack repository is maintained by the Core Working Group.
Sponsoring
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.

* CodSpeed for generously supporting us with benchmarks on their paid runners.
Special Thanks to
(In chronological order)
* @google for Google Web Toolkit (GWT), which aims to compile Java to JavaScript. It features a similar Code Splitting as webpack.
* @medikoo for modules-webmake, which is a similar project. webpack was born because of the desire for code splitting for modules such as 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.
* @sokra for creating webpack.
* Every early webpack user, which contributed to webpack by writing issues or PRs. You influenced the direction.
* All past and current webpack maintainers and collaborators.
* Everyone who has written a loader for webpack. You are the ecosystem...
* Everyone not mentioned here but that has also influenced webpack.
About
A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
