Latest Version

## Installation

```
npm install --save-dev rollup-plugin-scss sass
```

If any of them is installed, it will be used automatically, if both installed `sass` will be used.

## Usage

```js
// rollup.config.js
import scss from 'rollup-plugin-scss'

export default {
input: 'input.js',
output: {
file: 'output.js',
format: 'esm',
// Removes the hash from the asset filename
assetFileNames: '[name][extname]'
},
plugins: [
scss() // will output compiled styles to output.css
]
}

// OR

export default {
input: 'input.js',
output: { file: 'output.js', format: 'esm' },
plugins: [
scss({ fileName: 'bundle.css' }) // will output compiled styles to "bundle.css"
]
}

// OR

export default {
input: 'input.js',
output: { file: 'output.js', format: 'esm' },
plugins: [
scss() // will output compiled styles to "assets/output-123hash.css"
]
}
```

```js
// entry.js
import './reset.scss'
```

### Options

Options are passed to the sass compiler ([node-sass] by default). Refer to [ the Sass docs](https://sass-lang.com/documentation/js-api#options) for more details on these options.

One notable option is `indentedSyntax` which you'll need if you're parsing Sass syntax instead of Scss syntax. (e.g. when extracting a Vue `` tag) <br/>
By default the plugin will base the filename for the css on the bundle destination.

```js
scss({
// Defaults to output.css, Rollup may add a hash to this!
name: 'output.css',

// Literal asset filename, bypasses the automated filenaming transformations
fileName: 'output.css',

// Callback that will be called ongenerate with two arguments:
// - styles: the contents of all style tags combined: 'body { color: green }'
// - styleNodes: an array of style objects: { filename: 'body { ... }' }
output: function (styles, styleNodes) {
writeFileSync('bundle.css', styles)
},

// Disable any style output or callbacks, import as string
output: false,

// Enables/disables generation of source map (default: false)
sourceMap: true,

// Choose files to include in processing (default: ['/**/*.css', '/**/*.scss', '/**/*.sass'])
include: [],

// Choose files to exclude from processing (default: undefined)
exclude: [],

// Determine if node process should be terminated on error (default: false)
failOnError: true,

// Prefix global scss. Useful for variables and mixins.
prefix: `@import "./fonts.scss";`,

// A Sass (sass compatible) compiler to use
// - sass and node-sass packages are picked up automatically
// - you can use this option to specify custom package (e.g. a fork of one of them)
sass: require('node-sass'),

// Run postcss processor before output
processor: () => postcss([autoprefixer({ overrideBrowserslist: 'Edge 18' })]),

// Process resulting CSS
processor: (css, map) => ({
css: css.replace('/*date*/', '/* ' + new Date().toJSON() + ' */'),
map
}),

// or, just string (for backward compatiblity with v2 or simplicity)
processor: css =>
css.replace('/*date*/', '/* ' + new Date().toJSON() + ' */'),

// Log filename and size of generated CSS files (default: true)
verbose: true

// Add file/folder to be monitored in watch mode so that changes to these files will trigger rebuilds.
// Do not choose a directory where rollup output or dest is pointed to as this will cause an infinite loop
watch: 'src/styles/components',
watch: ['src/styles/components', 'src/multiple/folders']

// Any other options are passed to the sass compiler
includePaths: ...
})
```

## Examples

Using postcss + autoprefixer + includePaths (sass option)

```js
import scss from 'rollup-plugin-scss'
import postcss from 'postcss'
import autoprefixer from 'autoprefixer'

export default {
input: 'input.js',
output: {
file: 'output.js',
format: 'esm'
},
plugins: [
scss({
processor: () => postcss([autoprefixer()]),
includePaths: [
path.join(__dirname, '../../node_modules/'),
'node_modules/'
]
})
]
}
```

Minify CSS output:

```js
scss({
outputStyle: 'compressed'
})
```
