Live-Updating AMPs in Focus
Publishers are becoming increasingly interested in leveraging the real-time, live, nature of the Web to connect to Internet users as events and news develops. While that has not always been easy to do, it is starting to change.
The Accelerated Mobile Pages Project announced a beta for a new AMP component that updates page content dynamically without additional navigation or reload. Essentially, readers looking at an earlier version of the page will see new updates as they are published.
Publishers/developers have control over the content and can override the components defaults styles. What that means is that it is possible to apply a different style on new items, such as highlight the background for new items for a few seconds.
The new component also includes a customizable button which will make it possible users to pull in updates on demand.
Google project manager Eric Lindly went into some detail about how it actually works and the best method for implimentation on the AMP blog, but remember that this is still a beta so there will likely be changes made in the future.
