# tools.cssExtract

- **类型：**

```ts
type CSSExtractOptions = {
  pluginOptions?: Rspack.CssExtractRspackPluginOptions;
  loaderOptions?: Rspack.CssExtractRspackLoaderOptions;
};
```

- **默认值：**

```js
const defaultOptions = {
  pluginOptions: {
    ignoreOrder: true,
    // 默认值由 Rsbuild 的 output.distPath 和 output.filename 选项决定
    filename: 'static/css/[name].css',
    chunkFilename: 'static/css/async/[name].css',
  },
  loaderOptions: {},
};
```

通过 `tools.cssExtract` 可以更改 [CssExtractRspackPlugin](https://rspack.rs/zh/plugins/rspack/css-extract-rspack-plugin) 的配置。

:::info
该配置项的使用方式与 Rsbuild 完全一致。详细信息请参考 [Rsbuild - tools.cssExtract](https://v2.rsbuild.dev/zh/config/tools/css-extract)。
