The Simplest Way to Implement a News Feed in an Ionic Application

Basically, since most of the information I could find online was outdated, I thought I’d ask this question here. I don’t have any personal server that I can store data on, however, I would like to have an application with a newsfeed that I can post to whenever I want to. I was thinking of using Facebook, but most tutorials I found for using the facebook api in ionic was to have Facebook authentication. Another one I thought of was using (a free domain) and use their rest API to fetch Json Data, however, it only seems like websites are supported with the REST APi. What is the simplest way to implement this?
