Actually it would be better to cache the fetchArticleContent for more than 1 hour, no idea how to do that.

Actually it would be better to cache the fetchArticleContent for more than 1 hour, no idea how to do that.

If I'm not mistaken, you should just be able to change the value in the line const CACHE_TIMEOUT = 3600; to the actual amount of seconds you'd like to cache for, up to 24 hours (86400).
