I have been able to find nothing about storing information in a SharePoint Online app. I need to be able to pull down a bunch of information from the search API, store it, and be able to access it when the app is revisited. Ideally this would be shared between all users. Grabbing this info from the API on-demand is too slow for what I am trying to do.
EDIT: Initial idea is to create a list in my solution and deploy it with my app. I can create columns in it as needed and query it... unsure if this is going to be any faster than going to search.
