Storefront UI is installed as a dependency to your project:

```bash
npm install --save @borngroup/lightswitch-storefront-ui-vue
# or
yarn add @borngroup/lightswitch-storefront-ui-vue
```

Once the library is installed, you need to import its **root stylesheet**. It contains _global_ styles and SCSS variables. **Component styles** are automatically imported as part of `.vue` files for each component.

We recommend putting it in your `main.js` or the root component of your application.

```js
import "@borngroup/lightswitch-storefront-ui-vue/styles.scss";
```

That's all! Now you can import any of Storefront UI components like this:

```js
import { SfComponentName } from "@borngroup/lightswitch-storefront-ui-vue";
```

<div class="alert warning">

For best extendability and performance we ship Storefront UI as (unpackaged) source code which requires **webpack** in your project to use the library.

Storefront UI is working out of the box with **Nuxt** and **Vue CLI 2 & 3**!
In order to use it in custom projects you need the following webpack loaders: `css-loader@>1.0.1`, `scss-loader`, `sass-loader`, `vue-loader`

</div>

## Install custom font

StorefrontUI bases on [Raleway](https://fonts.google.com/specimen/Raleway) and [Roboto](https://fonts.google.com/specimen/Roboto) font styles. To include it in your project,
you need to add the following snippet in the `<head>` of your main `.html` file in a Vue project.

```html
<link rel="dns-prefetch" href="https://fonts.gstatic.com" />
<link
  rel="preconnect"
  href="https://fonts.gstatic.com"
  crossorigin="anonymous"
/>
<link
  rel="preload"
  href="https://fonts.googleapis.com/css?family=Raleway:300,400,400i,500,600,700|Roboto:300,300i,400,400i,500,700&display=swap"
  as="fetch"
  crossorigin="anonymous"
/>
<script type="text/javascript">
  !(function (e, n, t) {
    "use strict";
    var o =
        "https://fonts.googleapis.com/css?family=Raleway:300,400,400i,500,600,700|Roboto:300,300i,400,400i,500,700&display=swap",
      r = "__3perf_googleFonts_dc153";
    function c(e) {
      (n.head || n.body).appendChild(e);
    }
    function a() {
      var e = n.createElement("link");
      (e.href = o), (e.rel = "stylesheet"), c(e);
    }
    function f(e) {
      if (!n.getElementById(r)) {
        var t = n.createElement("style");
        (t.id = r), c(t);
      }
      n.getElementById(r).innerHTML = e;
    }
    e.FontFace && e.FontFace.prototype.hasOwnProperty("display")
      ? (t[r] && f(t[r]),
        fetch(o)
          .then(function (e) {
            return e.text();
          })
          .then(function (e) {
            return e.replace(/@font-face {/g, "@font-face{font-display:swap;");
          })
          .then(function (e) {
            return (t[r] = e);
          })
          .then(f)
          .catch(a))
      : a();
  })(window, document, localStorage);
</script>
```

This will make sure your font is loaded efficiently and won't affect the page initial load performance.

If you want to use your own font instead, use this [snippet generator](https://googlefonts.3perf.com/) to generate the related font snippet.

For Nuxt.js project, you can add the following to the `head` section of `nuxt.config.js` (or a specific page component).

```js
export default {
  head: {
    meta: [
      {
        rel: "preconnect",
        href: "https://fonts.gstatic.com/",
        crossorigin: "anonymous",
      },
      {
        rel: "preload",
        as: "style",
        href:
          "https://fonts.googleapis.com/css?family=Raleway:300,400,400i,500,600,700|Roboto:300,300i,400,400i,500,700&display=swap",
        crossorigin: "anonymous",
      },
      {
        rel: "stylesheet",
        href:
          "https://fonts.googleapis.com/css?family=Raleway:300,400,400i,500,600,700|Roboto:300,300i,400,400i,500,700&display=swap",
        media: "print",
        onload: "this.media='all'",
      },
    ],
  },
};
```

## Using with Nuxt

To use Storefront UI in a Nuxt project you need to include it's transpilation during build process using nuxt.config.js or your alternative webpack config.
For example in Nuxt 2-edge all you have to do is to add `/^@borngroup/lightswitch-storefront-ui/` to the [transpile.build](https://nuxtjs.org/api/configuration-build/#transpile) array e.g.

```
module.exports = {
	build: {
		transpile: [/^@borngroup/lightswitch-storefront-ui],
	},
}
```

Make sure that you already have all required webpack loaders.

## Customization

Storefront UI is very flexible in terms of customization. You can read [here](/setup-customization.md) about its capabilities.
