-## Getting Started
+
πΎπΎπΎIt's our absolute pleasure to announce Webpack 4 Support πππ
-To begin, you'll need to install `extract-css-chunks-webpack-plugin`:
+> **HEADLINES (May 2018): Now Independently supports Webpack 4:**
+> Yep that's right. The universal family is now fully Webpack 4. Thank you to all our users for your loyalty and patience! If you love Universal, then you are gonna fall head over heels when we bring out the main course!
-```bash
-npm install --save-dev extract-css-chunks-webpack-plugin
-```
+So... why did we rebuild `extract-css-chunks`? What does it offer?
-It's recommended to combine `extract-css-chunks-webpack-plugin` with the [`css-loader`](https://github.com/webpack-contrib/css-loader)
+It's got all the goodness of `mini-css-extract-plugin` but with 2 gleaming, sought after benefits.
-Then add the loader and the plugin to your `webpack` config. For example:
+Compared to the existing loaders, we are offering a single solution as opposed to needing to depend on multiple loaders to cater for different features:
-**style.css**
+## Perks
-```css
-body {
- background: green;
-}
-```
+- **HMR:** It also has first-class support for **Hot Module Replacement** across ALL those css files/chunks!!!
+- cacheable stylesheets
+- smallest total bytes sent compared to "render-path" css-in-js solutions that include your CSS definitions in JS
+- Faster than the V2!
+- Async loading
+- No duplicate compilation (performance)
+- Easier to use
+- Specific to CSS
+- SSR Friendly development build, focused on frontend DX
+- Works seamlessly with the Universal family
+- Works fantastically as a standalone style loader (You can use it for any webpack project! with no extra dependencies!)
+- Async styles do not render block webkit browsers, if you use the `insert` option
-**component.js**
+Additionally, if you are already a user of the universal family -- we will be waving goodbye to the mandatory `window.__CSS_CHUNKS__`.
-```js
-import './style.css';
-```
+The functionality is still available to you via chunk flushing, and it can come in super handy when needing to easily resolve style assets as urls that might need to be passed to a third party.
