CUNY Academic Commons

Here's background on how this is built:

- The list of sites that are the source for Latest News is defined here https://github.com/cuny-academic-commons/cac/blob/f3158f150819ff9c7ae901c07dc4ba4b215ac0e6/wp-content/mu-plugins/cac-functions.php#L341
- On the home page, the latest items from these source sites is pulled using the WP REST API. See https://github.com/cuny-academic-commons/cac/blob/f3158f150819ff9c7ae901c07dc4ba4b215ac0e6/wp-content/themes/bp-nelo/parts/home/latest-news.php#L3. I tried doing this with switch_to_blog(), but that function isn't sufficient - things like fetching post thumbnails failed because of limitations in blog-switching and persistent caching. I made a modification to the /posts/ endpoint on the source sites so that the post thumbnail is included in the payload https://github.com/cuny-academic-commons/cac/blob/f3158f150819ff9c7ae901c07dc4ba4b215ac0e6/wp-content/mu-plugins/cac-functions.php#L366
- Because we are using Featured Images, it's critical that items on in.commons and news.commons always have Featured Images. Scott, I've added you as a watcher so that this can become part of the team workflow.
- The API calls are cached, and the cache is invalidated when a new post appears on one of the source sites. https://github.com/cuny-academic-commons/cac/blob/f3158f150819ff9c7ae901c07dc4ba4b215ac0e6/wp-content/mu-plugins/cac-functions.php#L353
