Any asset file can be processed using `resources.PostCSS` which takes for argument the resource object and a slice of options listed below.
|
|
|
|
The resource will be processed using the project's or theme's own `postcss.config.js` or any file set with the `config` option.
|
|
|
|
|
|
```go-html-template
|
|
{{ $css := resources.Get "css/main.css" }}
|
|
{{ $style := $css | resources.PostCSS }}
|
|
```
|
|
|
|
{{% note %}}
|
|
Hugo Pipe's PostCSS requires the `postcss-cli` JavaScript package to be installed in the environment (`npm install -g postcss-cli`) along with any PostCSS plugin(s) used (e.g., `npm install -g autoprefixer`).
|
|
|
|
If you are using the Hugo Snap package, PostCSS and plugin(s) need to be installed locally within your Hugo site directory, e.g., `npm install postcss-cli` without the `-g` flag.

### Options
|
|
|
|
config [string]
|
|
: Path to the PostCSS configuration file
|
|
|
|
noMap [bool]
|
|
: Default is `true`. Disable the default inline sourcemaps
|
|
|
|
inlineImports [bool] {{< new-in "0.66.0" >}}
|
|
: Default is `false`. Enable inlining of @import statements. It does so recursively, but will only import a file once.
|
|
URL imports (e.g. `@import url('https://fonts.googleapis.com/css?family=Open+Sans&display=swap');`) and imports with media queries will be ignored.
|
|
Note that this import routine does not care about the CSS spec, so you can have @import anywhere in the file.
|
|
Hugo will look for imports relative to the module mount and will respect theme overrides.
|
|
|
|
_If no configuration file is used:_
|
|
|
|
use [string]
|
|
: List of PostCSS plugins to use
|
|
|
|
parser [string]
|
|
: Custom PostCSS parser
|
|
|
|
stringifier [string]
|
|
: Custom PostCSS stringifier
|
|
|
|
syntax [string]
|
|
: Custom postcss syntax
|
|
|
|
```go-html-template
|
|
{{ $style := resources.Get "css/main.css" | resources.PostCSS (dict "config" "customPostCSS.js" "noMap" true) }}
|
|
```
|
|
|
|
## Check Hugo Environment from postcss.config.js
|
|
|
|
{{< new-in "0.66.0" >}}
|
|
|
|
The current Hugo environment name (set by `--environment` or in config or OS environment) is available in the Node context, which allows constructs like this:
|
|
|
|
```js
|
|
module.exports = {
|
|
plugins: [
|
|
require('autoprefixer'),
|
|
...process.env.HUGO_ENVIRONMENT === 'production'
|
|
? [purgecss]
|
|
: []
|
|
]
|
|
}
|
|
``` |
