rollup-plugin-parcel-css

A Rollup plugin to use @parcel/css to handle CSS files

Usage

import css from "rollup-plugin-parcel-css";

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [css({ minify: true })],
};

Plugin Options

import type { TransformOptions, PseudoClasses } from "@parcel/css";

type LoaderName = "sass" | "less";

export type PluginOptions = {
  include?: string | RegExp | (string | RegExp)[];
  exclude?: string | RegExp | (string | RegExp)[];
  minify?: boolean;
  targets?: TransformOptions["targets"];
  cssModules?: boolean;
  pseudoClasses?: PseudoClasses;
  loaders?: LoaderName | LoaderName[] | (Loader | Loader)[];
};

CSS Modules

By default any file with name .module.* will be treated as CSS module. Setting option cssModules: true will force all files to be treated as CSS module

Sass

Enable Sass Loader

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [css({ loaders: "sass" })],
};

Sass options can be provided:

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [
    css({
      loaders: {
        type: "sass",
        options: {},
      },
    }),
  ],
};

Less

Enable Less Loader

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [css({ loaders: "less" })],
};

Loaders

Webpack-styled loaders. In case of mix project both Less & Sass can be enabled

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [css({ loaders: ["less", "sass"] })],
};

Or can bring own loader for cusstom file extensions or preprocessors; see Types definition for more details

export default {
  input: "./src/main.js",
  output: {
    file: "./build/app.js",
    format: "iife",
    sourcemap: true,
  },
  plugins: [css({ loaders: {
      test: /\.ext/;
  type: "custom-ext";
  options?: T;
  process: (code, filename , options) => {
        // process code, transform into css
        return {
            css: ""
        }
  }
  } })],
};
