Usage as Web Component

The component requires a type. It also allows for a carousel-height (in rem units), a fit-to-container property which causes it to size to its container (horizontally), and slick-options.

<link
  href="https://unpkg.com/@uportal/content-carousel/dist/slick-theme.css"
  rel="stylesheet"
/>
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/@uportal/content-carousel"></script>

<content-carousel
  type="rss"
  source="/hero.rss"
  slick-options='{ "slidesToShow": 1, "infinite": true, "arrows": true }'
  carousel-height="30rem"
  fit-to-container="true"
>
</content-carousel>

Options

• type (required, enum[rss, portlet, passthrough]): type of data source to use.
• source (optional, string): location or content to render in slides.
• slick-options (optional, slick settings): configuration for slick carousel.
• carousel-height (optional, string): css height to apply on slides.
• fit-to-container (optional, boolean): by default carousel will fit content, true will make carousel match width of surrounding container.

Types

There are three data source types currently supported RSS, Portlet, and Passthrough.

RSS

RSS can read any RSS feed that does not require authentication. The URL of the feed must be passed as the source attribute to the component.

<content-carousel type="rss" source="/content.rss"> </content-carousel>

Portlet

Portlet leverages the portlet registry to display slides. The URL to the registry must be passed as the source attribute to the component. The component will automatically authentice as the current user with uPortal. Specific portlet categories can be displayed by the component by changing the URL. For example /portletRegistry.json?category=Academics will display only portlets within that category.

<content-carousel type="portlet" source="/portletRegistry.json">
</content-carousel>

Passthrough

Pass through allows for arbitrary HTML to be rendered as slides. Add the HTML into the <content-carousel> and include class="slick-item" on each slide be be rendered.

<content-carousel type="passthrough">
  <div class="slick-item">arbitrary</div>
  <div class="slick-item">content</div>
  <div class="slick-item">displayed</div>
  <div class="slick-item">as</div>
  <div class="slick-item">slides</div>
</content-carousel>

Slots

The HTML content of the component can also be modified using slots.

Header

The header slot goes about the slides, and is outside the slide deck.

<content-carousel type="rss" source="/content.rss">
  <h1 slot="header">Example Header</h1>
</content-carousel>

Empty

The empty slot replaces the carousel when no content was found.

<content-carousel type="rss" source="/content.rss">
  <p slot="empty">Uh Oh, that couldn't be found.</p>
</content-carousel>

Slide

leveraging the Vue’s templating language within a slide will not work until https://github.com/vuejs/vue-web-component-wrapper/issues/8 is resolved

The slide slot the rendering of individual slides to be changed. The template has access to the following data to display:

interface CarouselItem {
  id: string;
  destinationUrl?: string;
  imageUrl?: string;
  altText?: string;
  title?: string;
  description?: string;
}

<content-carousel type="rss" source="example.rss">
  <template slot="slide" slot-scope="props">
    <h1 class="slick-item"></h1>
  </template>
</content-carousel>

Usage as Vue component

The component source can also be imported and used directly within other Vue projects.

import contentCarousel from '@uportal/content-carousel/src/components/ContentCarousel.vue';
