With Feedamic and Sitemapamic
Since 2.1.0 of Scheduled Cache Invalidator for Statamic, when the cache is invalidated, an event is dispatched.
And Feedamic (2.5.0) and Sitemapamic (3.2.0) are both ready to listen - and you don't need to do anything extra either.
Feedamic
Feedamic is our RSS feed generator for Statamic.
When the Scheduled Cache Invalidator invalidates an entry (or entries), the parent Collection handles are passed to Feedamic - and Feedamic will automatically clear the cache for any of your Feedamic feeds that use any of the Collections.
Sitemapamic
Sitemapamic is our sitemap generator for Statamic.
When the Scheduled Cache Invalidator invalidates an entry, your Sitemapamic cache will be cleared automatically.
