                    mode: "base64"
                },
                {

                    mode: "base64"
                },
                {
                    test: /\.less$/i,
                    mode: "less"
                }
            ]
        }) 
    ]
};

This plugins supports require forms of importing files.

const css = require("./styles.css"); /* creates a string that contains the content of the CSS file */
const parsedCss = require("./styles.less"); /* creates a string that contains the CSS code parsed from the LESS file */
const font = require("./font.woff"); /* creates a string with the content of the font in base64 data URL */

Options

include

Type: array or string Default: []

A single file, or array of files to include when minifying.

exclude

Type: array or string Default: []

A single file, or array of files to exclude when minifying.

rules

Type: Array Default: null

A collection of rules for processing imported files. Each element is defined as

{
    test: RegularExpression,
    mode: "plain" | "base64" | "css" | "less" | "sass",
    minimize: boolean
}

The option minimize works only for css, less and sass.

Why

With Web Component frameworks, its useful to be able to import the css for components in a variety of ways. Other solutions for Rollup either lack features or are large and bloated with extra features that some users may not need such as SASS or LESS support.
