Seamless integration between Rollup and PostCSS
Seamless integration between Rollup and PostCSS.
yarn add rollup-plugin-postcss --dev
You are viewing the docs for v1.0, for v0.5 please see here.
// rollup.config.js
import postcss from 'rollup-plugin-postcss'
export default {
plugins: [
postcss({
plugins: []
})
]
}
Then you can use CSS files:
import './style.css'
Note that the generated CSS will be injected to <head> by default, and the CSS string is also available as default export unless extract: true:
// Inject to `<head>` and also available as `style`
import style from './style.css'
It will also automatically use local PostCSS config files.
postcss({
extract: true
})
postcss({
modules: true,
// Or with custom options for `postcss-modules`
modules: {}
})
Install corresponding dependency:
Sass install node-sass: yarn add node-sass --devStylus Install stylus: yarn add stylus --devLess Install less: yarn add less --devThat's it, you can now import .styl .scss .sass .less files in your library.
For Sass/Scss Only.
Similar to how webpack's sass-loader works, you can prepend the path with ~ to tell this plugin to resolve in node_modules:
@import "~bootstrap/dist/css/bootstrap";
Type: string[]
Default: ['.css', '.sss', '.pcss']
This plugin will process files ending with these extensions and the extensions supported by custom loaders.
Type: Array
PostCSS Plugins.
Type: boolean object
Default: true
Inject CSS into <head>, it's always false when extract: true.
You can also use it as options for style-inject.
Type: boolean string
Default: false
Extract CSS to the same location where JS file is generated but with .css extension.
You can also set it to an absolute path.
Type: boolean object
Default: false
Enable CSS modules or set options for postcss-modules.
Type: boolean
Default: true
Automatically enable CSS modules for .module.css .module.sss .module.scss .module.sass .module.styl .module.stylus .module.less files.
Type: boolean function
Default: false
Use named exports alongside default export.
You can supply a function to control how exported named is generated:
namedExports(name) {
// Maybe you simply want to convert dash to underscore
return name.replace(/-/g, '_')
}
If you set it to true, the following will happen when importing specific classNames:
$ sign wrapped underlines, eg. -- => $__$$ signs, eg. switch => $switch$All transformed names will be logged in your terminal like:
Exported "new" as "$new$" in test/fixtures/named-exports/style.css
The original will not be removed, it's still available on default export:
import style, { class$_$name, class$__$name, $switch$ } from './style.css'
console.log(style['class-name'] === class$_$name) // true
console.log(style['class--name'] === class$__$name) // true
console.log(style['switch'] === $switch$) // true
Type: boolean object
Default: false
Minimize CSS, boolean or options for cssnano.
Type: boolean "inline"
Enable sourceMap.
Type: string function
PostCSS parser, like sugarss.
Type: string function
PostCSS Stringifier.
Type: string function
PostCSS Syntax.
Type: boolean
Enable PostCSS Parser support in CSS-in-JS.
Type: boolean object
Default: true
Load PostCSS config file.
Type: string
The path to config file, so that we can skip searching.
Type: object
ctx argument for PostCSS config file.
Note: Every keys you pass to config.ctx will be available under options inside
the postcss config.
// rollup.config.js
postcss({
config: {
ctx: {
foo: 'bar'
}
}
})
// postcss.config.js
module.exports = context => {
console.log(context.options.foo) // 'bar'
return {}
}
Type: name[] [name, options][]
Default: ['sass', 'stylus', 'less']
Use a loader, currently built-in loaders are:
sass (Support .scss and .sass)stylus (Support .styl and .stylus)less (Support .less)They are executed from right to left.
Type: Loader[]
An array of custom loaders, check out our sass-loader as example.
interface Loader {
name: string,
test: RegExp,
process: (this: Context, input: Payload) => Promise<Payload> | Payload
}
interface Context {
/** Loader options */
options: any
/** Sourcemap */
sourceMap: any
/** Resource path */
id: string
}
interface Payload {
/** File content */
code: string
/** Sourcemap */
map?: string | SourceMap
}
Type: id => void
A function to be invoked when an import for CSS file is detected.
