cm-ngx-video-lazyloader

cm-ngx-video-lazyloader is an Angular library for lazy loading videos using IntersectionObserver.

Install

npm install --save cm-ngx-video-lazyloader

Usage

1. Import CmNgxVideoLazyloaderModule into your root module.
2. Add lazyLoadVideo directive to the video tag.
3. Place the video url inside data-src attribute instead of src attribute. The url will be dynamically assinged to the src attribute when the video is in viewport.

Example:

<video lazyLoadVideo class="card-video" loop autoplay muted id="1" poster="https://example.org/assets/Americas-poster.jpg">
  <source data-src="https://example.org/assets/Americas.mp4" type="video/mp4" />
      Browser not supported
</video>

If you wish to lazy load the poster as well, then you can pass in an optional input param [lazyLoadPoster]="true" in the video tag and place the poster url inside the data-poster attribute. This attribute is set as false by default.

Example:

<video lazyLoadVideo [lazyLoadPoster]="true" data-poster="https://example.org/...></video>
