🎨 Universal Rollup plugin for styles: PostCSS, Sass, Less, Stylus and more.
@import statements inside regular CSS...and more!
# npm npm install -D rollup-plugin-styles # pnpm pnpm add -D rollup-plugin-styles # yarn yarn add rollup-plugin-styles --dev
// rollup.config.js import styles from "rollup-plugin-styles"; export default { output: { // Governs names of CSS files (for assets from CSS use `hash` option for url handler). // Note: using value below will put `.css` files near js, // but make sure to adjust `hash`, `assetDir` and `publicPath` // options for url handler accordingly. assetFileNames: "[name]-[hash][extname]", }, plugins: [styles()], };
After that you can import CSS files in your code:
import "./style.css";
Default mode is inject, which means CSS is embedded inside JS and injected into <head> at runtime, with ability to pass options to CSS injector or even pass your own injector.
CSS is available as default export in inject and extract modes, but if CSS Modules are enabled you need to use named css export.
// Injects CSS, also available as `style` in this example import style from "./style.css"; // Using named export of CSS string import { css } from "./style.css";
In emit mode none of the exports are available as CSS is purely processed and passed along the build pipeline, which is useful if you want to preprocess CSS before using it with CSS consuming plugins, e.g. rollup-plugin-lit-css.
PostCSS configuration files will be found and loaded automatically, but this behavior is configurable using config option.
/* Import from `node_modules` */ @import "bulma/css/bulma"; /* Local import */ @import "./custom"; /* ...or (if no package named `custom` in `node_modules`) */ @import "custom";
You can prepend the path with ~ to resolve in node_modules:
// Import from `node_modules` @import "~bulma/css/bulma"; // Local import @import "./custom"; // ...or @import "custom";
Also note that partials are considered first, e.g.
@import "custom";
Will look for _custom first (with the appropriate extension(s)), and then for custom if _custom doesn't exist.
styles({ mode: "inject", // Unnecessary, set by default // ...or with custom options for injector mode: [ "inject", { container: "body", singleTag: true, prepend: true, attributes: { id: "global" } }, ], // ...or with custom injector mode: ["inject", (varname, id) => `console.log(${varname},${JSON.stringify(id)})`], });
styles({ mode: "extract", // ... or with relative to output dir/output file's basedir (but not outside of it) mode: ["extract", "awesome-bundle.css"], });
// rollup.config.js import styles from "rollup-plugin-styles"; // Any plugin which consumes pure CSS import litcss from "rollup-plugin-lit-css"; export default { plugins: [ styles({ mode: "emit" }), // Make sure to list it after this one litcss(), ], };
styles({ modules: true, // ...or with custom options modules: {}, // ...additionally using autoModules autoModules: true, // ...with custom regex autoModules: /\.mod\.\S+$/, // ...or custom function autoModules: id => id.includes(".modular."), });
Install corresponding dependency:
For Sass support install sass or node-sass:
# npm npm install -D sass # pnpm pnpm add -D sass # yarn yarn add sass --dev
# npm npm install -D node-sass # pnpm pnpm add -D node-sass # yarn yarn add node-sass --dev
For Less support install less:
# npm npm install -D less # pnpm pnpm add -D less # yarn yarn add less --dev
For Stylus support install stylus:
# npm npm install -D stylus # pnpm pnpm add -D stylus # yarn yarn add stylus --dev
That's it, now you can import .scss .sass .less .styl .stylus files in your code.
See API Reference for Options for full list of available options.
Because alternatives did not look good enough - they are either too basic, too buggy or poorly maintained.
For example, the main alternative (and inspiration) is rollup-plugin-postcss, but at the time it is not actively maintained, has a bunch of critical bugs and subjectively lacks some useful features and quality of life improvements which should be a part of it.
With that said, here is the basic list of things which differentiate this plugin from the aforementioned one:
