See [PostCSS] docs for examples for your environment.
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
All of the options of purgecss are available to use with the plugins.
|
||
|
|
You will find below the main options available. For the complete list, go to the [purgecss documentation website](https://www.purgecss.com/configuration.html#options).
|
||
|
|
|
||
|
|
### `content` (**required**)
|
||
|
|
Type: `string | Object`
|
||
|
|
|
||
|
|
You can specify content that should be analyzed by Purgecss with an array of filenames or globs. The files can be HTML, Pug, Blade, etc.
|
||
|
|
|
||
|
|
### `extractors`
|
||
|
|
Type: `Array<Object>`
|
||
|
|
|
||
|
|
Purgecss can be adapted to suit your needs. If you notice a lot of unused CSS is not being removed, you might want to use a custom extractor.
|
||
|
|
More information about extractors [here](https://www.purgecss.com/extractors.html).
|
||
|
|
|
||
|
|
### `whitelist`
|
||
|
|
Type: `Array<string>`
|
||
|
|
|
||
|
|
You can whitelist selectors to stop Purgecss from removing them from your CSS. This can be accomplished with the options whitelist and whitelistPatterns.
|
||
|
|
|
||
|
|
### `whitelistPatterns`
|
||
|
|
Type: `Array<RegExp>`
|
||
|
|
|
||
|
|
You can whitelist selectors based on a regular expression with whitelistPatterns.
|
||
|
|
|
||
|
|
### `rejected`
|
||
|
|
Type: `boolean`
|
||
|
|
Default value: `false`
|
||
|
|
|
||
|
|
If true, purged selectors will be captured and rendered as PostCSS messages.
|
||
|
|
Use with a PostCSS reporter plugin like [`postcss-reporter`](https://github.com/postcss/postcss-reporter)
|
||
|
|
to print the purged selectors to the console as they are processed.
|
||
|
|
|
||
|
|
### `keyframes`
|
||
|
|
Type: `boolean`
|
||
|
|
Default value: `false`
|
||
|
|
|
||
|
|
If you are using a CSS animation library such as animate.css, you can remove unused keyframes by setting the keyframes option to true.
|
||
|
|
|
||
|
|
#### `fontFace`
|
||
|
|
Type: `boolean`
|
||
|
|
Default value: `false`
|
||
|
|
|
||
|
|
If there are any unused @font-face rules in your css, you can remove them by setting the fontFace option to true.
