Deprecated options

This page lists configuration options that have been deprecated in Rspack.

These options are kept for backward compatibility only and should not be used in new projects.

experiments.css

• Type: boolean
• Default: false

:::warning Deprecated This option is deprecated since Rspack 2.0. Users now need to manually add CSS rules to enable CSS support. In a future version, Rspack will automatically add CSS-related default rules. :::

Migration

To use CSS in Rspack 2.0, you need to manually add CSS rules to your configuration:

export default {
  module: {
    rules: [
      {
        test: /\.css$/,
        type: 'css/auto',
      },
    ],
  },
};

Legacy usage (deprecated)

export default {
  experiments: {
    css: true,
  },
};

experiments.incremental

This option has been moved to top-level incremental.

rules[].loaders

An array to pass the loader package name and its options.

:::warning This option has been deprecated. Use rules[].use instead. :::
