ImageLoading enum

Loading strategies determining when the browser initiates image network fetching.

Controls the HTML loading attribute on <img> elements. By default, bloomImage and BloomImage specify ImageLoading.lazy to minimize bandwidth consumption and avoid competing with critical resources during initial page load.

For above-the-fold hero images or critical visual elements, specify ImageLoading.eager (or set priority: true on bloomImage) to prevent delayed Largest Contentful Paint (LCP).

bloomImage(
  src: '/assets/banner.webp',
  alt: 'Homepage Banner',
  loading: ImageLoading.eager,
);

Values

lazy → const ImageLoading

Defers loading the image until it reaches a calculated distance from the viewport.

Recommended for all below-the-fold images to conserve network bandwidth and speed up the initial page render.

const ImageLoading('lazy')
eager → const ImageLoading

Loads the image immediately upon DOM parsing, regardless of viewport position.

Recommended for above-the-fold hero images, key product shots, and critical UI elements contributing directly to Largest Contentful Paint (LCP).

const ImageLoading('eager')
