+# cssnano-webpack-plugin
+
+This plugin uses [cssnano](https://cssnano.co) to optimize and minify your CSS.
+
+Fully integrated in Webpack ecosystem: based on compiler hooks, respecting default Webpack output sources and compatible with other plugins like *SourceMapDevToolPlugin* or *webpack-subresource-integrity*.
+
+Just like [optimize-css-assets-webpack-plugin](https://github.com/NMFR/optimize-css-assets-webpack-plugin) but more accurate with source maps and assets using query string.
+
+Works with Webpack 4+.
+
+## Getting Started
+
+First, install `cssnano-webpack-plugin`:
+
+```console
+$ npm install cssnano-webpack-plugin --save-dev
+```
+
+Then add the plugin to your `webpack` configuration. For example:
+
+**webpack.config.js**
+
+```js
+const CssnanoPlugin = require('cssnano-webpack-plugin');
+
+module.exports = {
+  module: {
+    loaders: [
+      {
+        test: /.s?css$/,
+        use: [
+          MiniCssExtractPlugin.loader,
+          'css-loader',
+          'sass-loader'
+        ]
+      }
+    ]
+  },
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin()
+    ]
+  }
+};
+```
+
+This will enable CSS optimization only in production mode. If you want to run it also in development, put the plugin configuration in the `plugins` option array.
+
+## Options
+
+### `test`
+
+Type: `String|RegExp|Array<String|RegExp>` - default: `/\.css(\?.*)?$/i`
+
+Test to match files against.
+
+```js
+module.exports = {
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin({
+        test: /\.foo\.css$/i
+      })
+    ]
+  }
+};
+```
+
+`include` and `exclude` options are also supported (see [module rules](https://webpack.js.org/configuration/module)).
+
+### `sourceMap`
+
+Type: `Boolean|Object` - default: `false`
+
+Enable (and configure) source map support. Use [PostCss SourceMap options](https://github.com/postcss/postcss-loader#sourcemap). Default configuration when enabled: `{ inline: false }`.
+
+```js
+module.exports = {
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin({
+        sourceMap: true
+      })
+    ]
+  }
+};
+```
+
+### `cssnanoOptions`
+
+Type: `Object` - default: `{ preset: 'default' }`
+
+Cssnano optimisations [options](https://cssnano.co/guides/optimisations).
+
+```js
+module.exports = {
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin({
+        cssnanoOptions: ['default', {
+          discardComments: { removeAll: true }
+        }]
+      })
+    ]
+  }
+};
+```
+
+## Examples
+
+### Use sourcemaps
+
+Don't forget to enable `sourceMap` options for all loaders.
+
+```js
+const CssnanoPlugin = require('cssnano-webpack-plugin');
+
+module.exports = {
+  module: {
+    loaders: [
+      {
+        test: /.s?css$/,
+        use: [
+          MiniCssExtractPlugin.loader,
+          { loader: 'css-loader', options: { sourceMap: true } },
+          { loader: 'sass-loader', options: { sourceMap: true } }
+        ]
+      }
+    ]
+  },
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin({
+        sourceMap: true
+      })
+    ]
+  }
+};
+```
+
+### Remove all comments
+
+Remove all comments (including comments starting with `/*!`).
+
+```js
+module.exports = {
+  optimization: {
+    minimizer: [
+      new CssnanoPlugin({
+        cssProcessorPluginOptions: {
+         preset: ['default', { discardComments: { removeAll: true } }]
+        }
+      })
+    ]
+  }
+};
+```
