Feed Page

User Interface

• The feed page displays recent actions to a user's subscribed sections. These actions may include homework assignments that were added, updated, or deleted, or a new lecture posted on Wednesday at 8:00am.

Client

• Client sends request to server for data it needs (sections + courses)
• Data is received and the client applies to to the feed page + calendar and any other place needed.
• Client also opens web socket connection with the server to await updates to requested data. Any updates replace data that is currently in the app

Server

• The server awaits client requests for specific realms (sections, courses, etc.)
• Upon receiving a request, if the realms requested aren't cached, the server will get the data it needs from the API(s) and caches it temporarily (cache age must be discussed more)
• The server can use this cache for further requests for the same data
• When the server detects NEW data (after the cache expires), it can update clients through their websocket connection if they have requested such, now expired, data in the past.

Permissions

• Verified users (CA, Professors) should be able to add homeworks/update sections and courses, creating items to display on the user's feed
