Live content updates with <amp-live-list>

Another component for updating content dynamically is amp-live-list. Despite its similar name, it functions quite differently to amp-list. The main differences are as follows:

  • amp-live-list polls the source URL for new content at defined intervals, while amp-list performs a single fetch from a specified server endpoint
  • amp-live-list works with AMP-HTML pages, while amp-list deals with JSON data

Target use cases for amp-live-list include live blogs, breaking-news feeds, or any kind of live data that updates at intervals, such as sports scoreboards.


Note that amp-live-list will request updates from the URL it was visited on. So if the page is served via the AMP Cache, then amp-live-list will request updates from the AMP Cache URL. In practice, this can mean slower updates than if being updated from the original URL, depending on how frequently the AMP Cache refreshes from your original page, and that depends at least in part on the caching headers...
