[postcss][postcss]-use ![Build Status][ci]

> Enable PostCSS plugins directly in your stylesheet.

``css
@use postcss-preset-env(stage: 0, browsers: "last 2 versions");

h1 {
& a {
color: red
}
}
`

Install

With npm do:

`
npm install postcss-use --save
`

Example

Options may be passed into plugins as a JSON object, an array, a hash map, or
as declarations. Hash maps will follow the format of
option: value, option2: value2.

#### Standard syntax

With [postcss-discard-comments]:

`css
@use postcss-discard-comments(removeAll: true);
/! test /
h1 {
color: red
}
`

#### Alternative syntax

You may also use configuration blocks that are more CSS-like. Note that root
array options cannot be parsed by this method.

`css
@use postcss-discard-comments {
removeAll: true
}
`

$3

`css
h1 {
color: red
}
`

API

$3

#### options

##### modules

Type: array|string
Required option.

The modules option specifies a list of allowable PostCSS Plugins, expressed
as a String, Array, or RegExp. By default, all plugins are disabled in
order to prevent malicious usage in browser environments.

`js
use({
// allow plugins starting with autoprefixer, postcss, precss, and cssnano
modules: [
/^autoprefixer/,
/^postcss/,
/^precss/,
/^cssnano/
]
})
`

`js
use({
// allow autoprefixer, postcss-preset-env, and postcss-flexbugs-fixes
modules: [ 'autoprefixer', 'postcss-preset-env', 'postcss-flexbugs-fixes' ]
})
`

Setting the option to "*" will allow PostCSS Use to require any plugins. This
is not recommended for environments where you may be accepting arbitrary user
input; use at your own risk.

##### resolveFromFile

Type: boolean (default: false)

The resolveFromFile option specifies whether plugins should be resolved
relative to the file that referenced them. This may be used to enable the usage
of different versions of the same plugin. By default, it is disabled.

`js
use({
resolveFromFile: true
})
`

##### options

Type: object (default: {})

The options option specifies individual options for specific plugins by
plugin name.

`js
use({
options: {
'postcss-preset-env': {
stage: 0,
browsers: 'last two versions'
}
}
})
``

Usage

See the PostCSS documentation for
examples for your environment.
