| -## Usage |
21 |
| - |
22 |
| -### With mini-css-extract-plugin |
23 |
| - |
24 |
| -```js |
25 |
| -const path = require('path') |
26 |
| -const glob = require('glob') |
27 |
| -const MiniCssExtractPlugin = require('mini-css-extract-plugin') |
28 |
| -const PurgecssPlugin = require('purgecss-webpack-plugin') |
29 |
| - |
30 |
| -const PATHS = { |
31 |
| - src: path.join(__dirname, 'src') |
32 |
| -} |
33 |
| - |
34 |
| -module.exports = { |
35 |
| - entry: './src/index.js', |
36 |
| - output: { |
37 |
| - filename: 'bundle.js', |
38 |
| - path: path.join(__dirname, 'dist') |
39 |
| - }, |
40 |
| - optimization: { |
41 |
| - splitChunks: { |
42 |
| - cacheGroups: { |
43 |
| - styles: { |
44 |
| - name: 'styles', |
45 |
| - test: /\.css$/, |
46 |
| - chunks: 'all', |
47 |
| - enforce: true |
48 |
| - } |
49 |
| - } |
50 |
| - } |
51 |
| - }, |
52 |
| - module: { |
53 |
| - rules: [ |
54 |
| - { |
55 |
| - test: /\.css$/, |
56 |
| - use: [ |
57 |
| - MiniCssExtractPlugin.loader, |
58 |
| - "css-loader" |
59 |
| - ] |
60 |
| - } |
61 |
| - ] |
62 |
| - }, |
63 |
| - plugins: [ |
64 |
| - new MiniCssExtractPlugin({ |
65 |
| - filename: "[name].css", |
66 |
| - }), |
67 |
| - new PurgecssPlugin({ |
68 |
| - paths: glob.sync(`${PATHS.src}/**/*`, { nodir: true }), |
69 |
| - }), |
70 |
| - ] |
71 |
| -} |
72 |
| -``` |
73 |
| -### Multiple paths |
74 |
| -If you need multiple paths use the npm package `glob-all` instead of `glob`, then you can use this syntax: |
75 |
| -```javascript |
76 |
| -new PurgecssPlugin({ |
77 |
| - paths: glob.sync([ |
78 |
| - // ... |
79 |
| - ]) |
80 |
| -}), |
81 |
| -``` |
82 |
| -to filter out directories see the glob-all documentation [here](https://www.npmjs.com/package/glob-all#filtering-out-directories). |
83 |
| - |
84 |
| -### Webpack 3 (with extract-text-webpack-plugin) |
85 |
| -```js |
86 |
| -const path = require('path') |
87 |
| -const glob = require('glob') |
88 |
| -const ExtractTextPlugin = require('extract-text-webpack-plugin') |
89 |
| -const PurgecssPlugin = require('purgecss-webpack-plugin') |
90 |
| - |
91 |
| -const PATHS = { |
92 |
| - src: path.join(__dirname, 'src') |
93 |
| -} |
94 |
| - |
95 |
| -module.exports = { |
96 |
| - entry: './src/index.js', |
97 |
| - output: { |
98 |
| - filename: 'bundle.js', |
99 |
| - path: path.join(__dirname, 'dist') |
100 |
| - }, |
101 |
| - module: { |
102 |
| - rules: [ |
103 |
| - { |
104 |
| - test: /\.css$/, |
105 |
| - use: ExtractTextPlugin.extract({ |
106 |
| - fallback: 'style-loader', |
107 |
| - use: 'css-loader?sourceMap' |
108 |
| - }) |
109 |
| - } |
110 |
| - ] |
111 |
| - }, |
112 |
| - plugins: [ |
113 |
| - new ExtractTextPlugin('[name].css?[hash]'), |
114 |
| - new PurgecssPlugin({ |
115 |
| - paths: glob.sync(`${PATHS.src}/**/*`, { nodir: true }) |
116 |
| - }) |
117 |
| - ] |
118 |
| -} |
| 8 | +npm i -D purgecss-webpack-plugin |
119 | 9 | ```
|
120 |
| - |
121 |
| -### Options |
122 |
| - |
123 |
| -The options available in purgecss [Configuration](https://www.purgecss.com/configuration.html) are also available in the webpack plugin with the exception of css and content. |
124 |
| - |
125 |
| -* #### paths |
126 |
| - |
127 |
| -With the webpack plugin, you can specified the content that should be analyzed by purgecss with an array of filename. It can be html, pug, blade, ... files. You can use a module like `glob` or `glob-all` to easily get a list of files. |
128 |
| - |
129 |
| -```js |
130 |
| -const PurgecssPlugin = require('purgecss-webpack-plugin') |
131 |
| -const glob = require('glob') |
132 |
| -const PATHS = { |
133 |
| - src: path.join(__dirname, 'src') |
134 |
| -} |
135 |
| - |
136 |
| -// In the webpack configuration |
137 |
| -new PurgecssPlugin({ |
138 |
| - paths: glob.sync(`${PATHS.src}/**/*`, { nodir: true }) |
139 |
| -}) |
140 |
| -``` |
141 |
| - |
142 |
| -If you want to regenerate the paths list on every compilation (e.g. with `--watch`), then you can also pass a function: |
143 |
| -```js |
144 |
| -new PurgecssPlugin({ |
145 |
| - paths: () => glob.sync(`${PATHS.src}/**/*`, { nodir: true }) |
146 |
| -}) |
147 |
| -``` |
148 |
| - |
149 |
| -* #### only |
150 |
| - |
151 |
| -You can specify entrypoints to the purgecss-webpack-plugin with the option only: |
152 |
| - |
153 |
| -```js |
154 |
| -new PurgecssPlugin({ |
155 |
| - paths: glob.sync(`${PATHS.src}/**/*`, { nodir: true }), |
156 |
| - only: ['bundle', 'vendor'] |
157 |
| -}) |
158 |
| -``` |
159 |
| - |
160 |
| -* #### whitelist, whitelistPatterns and whitelistPatternsChildren |
161 |
| - |
162 |
| -Similar as for the `paths` option, you also can define functions for the these options: |
163 |
| - |
164 |
| -```js |
165 |
| -function collectWhitelist() { |
166 |
| - // do something to collect the whitelist |
167 |
| - return ['whitelisted']; |
168 |
| -} |
169 |
| -function collectWhitelistPatterns() { |
170 |
| - // do something to collect the whitelist |
171 |
| - return [/^whitelisted-/]; |
172 |
| -} |
173 |
| - |
174 |
| -function collectWhitelistPatternsChildren() { |
175 |
| - // do something to collect the whitelist |
176 |
| - return [/^whitelisted-/]; |
177 |
| -} |
178 |
| - |
179 |
| -// In the webpack configuration |
180 |
| -new PurgecssPlugin({ |
181 |
| - whitelist: collectWhitelist, |
182 |
| - whitelistPatterns: collectWhitelistPatterns, |
183 |
| - whitelistPatternsChildren: collectWhitelistPatternsChildren |
184 |
| -}) |
185 |
| -``` |
186 |
| - |
187 |
| -* #### rejected |
188 |
| - |
189 |
| -If `true` all removed selectors are added to the [Stats Data](https://webpack.js.org/api/stats/) as `purged`. |
