If you need a more advanced user interface, the option might be use the UI components that provides a set of reusable React components just to plug and play. **The UI components are compatible with v5.x and ahead**.

To install install the dependency in a local project.

:::caution

The UI components are in _experimental_ mode, currently used to build the main user interface [`@verdaccio/ui-theme`](https://github.com/verdaccio/verdaccio/tree/master/packages/plugins/ui-theme), If you are willing to use it **feedback is welcome**.

:::

```bash
npm i -D @verdaccio/ui-components@6-next
```

## How to use it {#how-to-useit}

There are a set of tools can be used in order to build your own user interface:

- `components`: Independent components to use to build different layouts, all components are based on [MUI (Material UI)](https://mui.com/).
- `providers`: Providers are useful components that uses the React [`Context`](https://reactjs.org/docs/context.html), for instance, the `VersionProvider` connects the Redux store with independent components. The `AppConfigurationProvider` is able to read the
- `store`: The Redux store powered by [`Rematch`](https://rematchjs.org), could be used with the global object `__VERDACCIO_BASENAME_UI_OPTIONS` that verdaccio uses to provide the UI configuration.
- `theme`: The `ThemeProvider` is an abstraction of the _material-ui_ theme provider.
- `sections`: A group of components to setup quickly sections of the application, like the sidebar, header of footer.
- `layouts`: Are the combination of one or more sections ready to use.
- `hooks`: A collection of useful React hooks.

The combination of them depend of your needs, it could be used to inject custom components, routes or addition of new pages or components.

## Examples {#examples}

```jsx
import React from 'react';
import { Route, Router, Switch } from 'react-router-dom';
import { Provider } from 'react-redux';
import {
  Home,
  store,
  Loading,
  NotFound,
  Route as Routes,
  TranslatorProvider,
  VersionProvider,
  loadable,
} from '@verdaccio/ui-components';

// to enable webpack code splitting
const VersionPage = loadable(() => import('../pages/Version'));

const App: React.FC = () => {
  // configuration from config.yaml
  const { configOptions } = useConfig();
  const listLanguages = [{lng: 'en-US', icon: <someSVGIcon>, menuKey: 'lng.english'}];
  return (
      <Provider store={store}>
        <AppConfigurationProvider>
          <ThemeProvider>
            <TranslatorProvider i18n={i18n} listLanguages={listLanguages} onMount={() => {}}>
              <Suspense fallback={<Loading />}>
                <Router history={history}>
                  <Header HeaderInfoDialog={CustomInfoDialog} />
                    <Switch>
                      <Route exact={true} path={Routes.ROOT}>
                        <Home />
                      </Route>
                      <Route exact={true} path={Routes.SCOPE_PACKAGE}>
                        <VersionProvider>
                          <VersionPage />
                        </VersionProvider>
                      </Route>
                    </Switch>
                </Router>
                {configOptions.showFooter && <Footer />}
              </Suspense>
            </TranslatorProvider>
