css-url-relative-plugin

Webpack plugin to convert css url(...) to relative path (only support webpack 4).

This plugin aim to solve the problem that webpack generate incorrect relative path when your publicPath is empty (defaults to '') or './', it will replace incorrect path in css url(...)s with correct relative path at end of webpack compilation process.

For example:

/*
 * /project
 * |- dist
 * |  |- xxx.hash.png
 * |  |- page
 * |     |- index.hash.css
 * |- src
 *    |- img
 *    |  |- xxx.png
 *    |- page
 *       |- index.css
 */
/* page/index.css (original css code you write) */
body {
  background: url(../img/xxx.png)
}

/* page/index.hash.css (webpack generated) */
body {
  /*
   * css-url-relative-plugin will generate: url(../xxx.hash.png)
   */
  background: url(xxx.hash.png)
}

As you can see, the image path in url(...) is relative to output dir, not the css file.

Usage

const CssUrlRelativePlugin = require('css-url-relative-plugin')

module.exports = {
  ...
  plugins: [
    new CssUrlRelativePlugin(/* options */)
  ]
}

Options

root

Like root option in css-loader, it's the path to resolve URLs.
