Theme package from lundium contains basic theme for components. In order to use it, we first have to import library into project:
yarn add @lundium/theme-basic
npm install @lundium/theme-basic
Then, we can load minified styled inside of application root:
import '@lundium/theme-basic/dist/index.css';
If you want to use only a part of predefined styles, you can use sass source files. They can be imported in a same way as you'd partialy import bootstrap files: (into you root scss file preferably)
@import 'node_modules/@lundium/theme-basic/scss/front.scss';
