Extracts and exports all CSS files that have been imported as a module, preserving or not the original path of the asset.
Extracts and exports all CSS files that have been imported as a module, preserving or not the original path of the asset.
In addition to this a styles property can be added to the metadata of each entry that imports one or more CSS files.
The
stylesproperty contains a list of paths to the generated assets which can, for example, be used by other plugins to generate HTML template.
With yarn:
yarn add --dev rollup-plugin-css-export
With npm:
npm install --save-dev rollup-plugin-css-export
If you want to import libraries directly from
node_modules(e.g. normalize.css) you may need to install the @rollup/plugin-node-resolve plugin.
| Name | Type | Default | Description |
|---|---|---|---|
| metaKey? | string | Symbol | undefined |
The name of the metadata key. When the value is nullish the plugin will not process or export any metadata. |

| exclude? | String | RegExp | Array[...String|RegExp] | undefined |

Metadata are not directly accessible in the bundle. You have to retrieve the extended information from the module with the this.getModuleInfo method.
import css from "rollup-plugin-css-export"; const metaKey = Symbol("styles"); export default { input: ["src/red.js", "src/blue.js", "src/purple.js"], output: { dir: "dist", // preserveModules: true, }, plugins: [ css({ metaKey }), { name: "your-plugin", generateBundle(_, bundle) { Object.entries(bundle).forEach(([id, entry]) => { if (entry.isEntry) { const info = this.getModuleInfo(entry.facadeModuleId); console.log("META:", id, info.meta[metaKey]); } }); }, }, ], };
