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.

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](https://www.2ality.com/2014/09/es6-modules-final.html), [CommonJS](http://wiki.commonjs.org/), and [AMD](https://github.com/amdjs/amdjs-api/wiki/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**](https://webpack.js.org/guides/getting-started) guide and the [other guides](https://webpack.js.org/guides/). ### Browser Compatibility webpack supports all browsers that are [ES5-compliant](https://kangax.github.io/compat-table/es5/) (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](https://webpack.js.org/guides/shimming/) before using these expressions.

Concepts

### [Plugins](https://webpack.js.org/plugins/) webpack has a [rich plugin interface](https://webpack.js.org/plugins/). 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][mini-css] | ![mini-css-npm] | ![mini-css-size] | Extracts CSS into separate files. It creates a CSS file per JS file which contains CSS. | | [compression-webpack-plugin][compression] | ![compression-npm] | ![compression-size] | Prepares compressed versions of assets to serve them with Content-Encoding | | [html-webpack-plugin][html-plugin] | ![html-plugin-npm] | ![html-plugin-size] | Simplifies creation of HTML files (`index.html`) to serve your bundles | [common-npm]: https://img.shields.io/npm/v/webpack.svg [mini-css]: https://github.com/webpack-contrib/mini-css-extract-plugin [mini-css-npm]: https://img.shields.io/npm/v/mini-css-extract-plugin.svg [mini-css-size]: https://packagephobia.com/badge?p=mini-css-extract-plugin [component]: https://github.com/webpack-contrib/component-webpack-plugin [component-npm]: https://img.shields.io/npm/v/component-webpack-plugin.svg [component-size]: https://packagephobia.com/badge?p=component-webpack-plugin [compression]: https://github.com/webpack-contrib/compression-webpack-plugin [compression-npm]: https://img.shields.io/npm/v/compression-webpack-plugin.svg [compression-size]: https://packagephobia.com/badge?p=compression-webpack-plugin [html-plugin]: https://github.com/jantimon/html-webpack-plugin [html-plugin-npm]: https://img.shields.io/npm/v/html-webpack-plugin.svg [html-plugin-size]: https://packagephobia.com/badge?p=html-webpack-plugin ### [Loaders](https://webpack.js.org/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](https://webpack.js.org/api/loaders/) using Node.js. Loaders are activated by using `loadername!` prefixes in `require()` statements, or are automatically applied via regex from your webpack configuration. #### Files | Name | Status | Install Size | Description | | :-----------------: | :---------: | :----------: | :---------------------------------------------------------------------------------------- | | [raw-loader][raw] | ![raw-npm] | ![raw-size] | Loads raw content of a file (utf-8) | | [val-loader][val] | ![val-npm] | ![val-size] | Executes code as module and considers exports as JS code | | [url-loader][url] | ![url-npm] | ![url-size] | Works like the file loader, but can return a Data Url if the file is smaller than a limit | | [file-loader][file] | ![file-npm] | ![file-size] | Emits the file into the output folder and returns the (relative) url | [raw]: https://github.com/webpack-contrib/raw-loader [raw-npm]: https://img.shields.io/npm/v/raw-loader.svg [raw-size]: https://packagephobia.com/badge?p=raw-loader [val]: https://github.com/webpack-contrib/val-loader [val-npm]: https://img.shields.io/npm/v/val-loader.svg [val-size]: https://packagephobia.com/badge?p=val-loader [url]: https://github.com/webpack-contrib/url-loader [url-npm]: https://img.shields.io/npm/v/url-loader.svg [url-size]: https://packagephobia.com/badge?p=url-loader [file]: https://github.com/webpack-contrib/file-loader [file-npm]: https://img.shields.io/npm/v/file-loader.svg [file-size]: https://packagephobia.com/badge?p=file-loader #### JSON | Name | Status | Install Size | Description | | :---------------------------------------------------------------------------------------------------------------------------------------: | :---------: | :----------: | :------------------------------: | |
