Components

Asset

/**
 * Renders an asset component (Image, Video, or Lottie) dynamically based on the type provided in the payload.
 *
 * @param {Object} Astro.props - The props object passed into the component.
 * @param {Object} Astro.props.payload - Contains asset data and options.
 * @param {string} Astro.props.payload.type - The type of the asset, which determines which component to render. Expected values are:
 *  - `"Image"`: Renders the `Image` component.
 *  - `"Video"`: Renders the `Video` component.
 *  - `"Lottie"`: Renders the `Lottie` component.
 *
 * @example Usage:

  payload={{
    type: "Image",
    url: "https://example.com/image.jpg",
    alt: "Example Image",
    customClass: "image-class",
  }}
/>

<Asset
  payload={{
    type: "Lottie",
    url: "https://example.com/animation.json",

    attributes: { controls: true, poster: "https://example.com/poster.jpg" },
    width: 1280,
    height: 720
  }}
/>

Type Image

/**
 * Renders an image element with lazy loading, aspect ratio, srcset, and other configurable attributes.
 * 
 * Dynamic Behavior:
 * - Lazy Loading: If `lazy` is `true`, the `data-src` and `data-srcset` attributes are used instead of `src` and `srcset`, enabling lazy loading.
 * - Aspect Ratio: If `aspectRatio` is `true` and both `width` and `height` are provided, an `aspect-ratio` style is applied to maintain the image's aspect ratio.
 * - Srcset: Automatically generates a `srcset` for responsive images if `width` is provided in the `attributes`.
 *
 * @param {Object} Astro.props - The props object passed into the component.
 * @param {Object} Astro.props.payload - Contains image-related data and options.
 * @param {string} Astro.props.payload.url - The image URL.
 * @param {string} [Astro.props.payload.sizes] - The sizes attribute for responsive images.
 * @param {string} [Astro.props.payload.alt] - The alt text for the image (important for accessibility).
 * @param {string} [Astro.props.payload.customClass] - Custom classes to apply to the image.
 * @param {boolean} [Astro.props.payload.lazy=true] - Enables lazy loading for the image. Default is `true`.
 * @param {boolean} [Astro.props.payload.aspectRatio=true] - Enables aspect ratio styling for the image. Default is `true`.
 * @param {boolean} [Astro.props.payload.decodingAsync=true] - Determines if the image should be decoded asynchronously. Default is `true`.
 * @param {boolean} [Astro.props.payload.fetchPriority=false] - Determines if the image should have high fetch priority. Default is `false`.
 * @param {Object} [Astro.props.payload.attributes] - Additional image attributes like width, height, etc.
 *
 * @example Usage:
