1698 // The finalsclub backchannel server uses socket.io to handle communication between the server and
1699 // the browser which facilitates near realtime interaction. This allows the user to post questions
1700 // and comments and other users to get those almost immediately after they are posted, without
1701 // reloading the page or pressing a button to refresh.
1703 // The server code itself is fairly simple, mainly taking incomming messages from client browsers,
1704 // saving the data to the database, and then sending it out to everyone else connected.
1707 // Posts - Posts are the main items in backchannel, useful for questions or discussion points
1708 // [[ example object needed with explanation E.G:
1710 Post: { postID: '999-1',
1712 userName: 'Bob Jones',
1713 userAffil: 'Instructor',
1714 body: 'This is the text content of the post.',
1715 comments: { {<commentObj>, <commentObj>, ...},
1717 votes: [ <userID>, <userID>, ...],
1718 reports: [ <userID>, <userID>, ...]
1720 Comment: { body: 'foo bar', userName: 'Bob Jones', userAffil: 'Instructor' }
1722 if anonymous: userName => 'Anonymous', userAffil => 'N/A'
1727 // Comments - Comments are replies to posts, for clarification or answering questions
1728 // [[ example object needed]]
1729 // Votes - Votes signifyg a users approval of a post
1730 // [[ example object needed]]
1731 // Flags - Flagging a post signifies that it is against the rules, 2 flags moves it to the bottomw
1732 // [[ example object needed]]
1736 // body - Main content of the post
1737 // userId - Not currently used, but would contain the users id that made the post
1738 // userName - Users name that made post
1739 // userAffil - Users affiliation to their school
1740 // public - Boolean which denotes if the post is public to everyone, or private to school users only
1741 // date - Date post was made, updates when any comments are made for the post
1742 // comments - An array of comments which contain a body, userName, and userAffil
1743 // votes - An array of user ids which are the users that voted
1744 // [[ example needed ]]
1745 // reports - An array of user ids which are the users that reported the post
1746 // [[ reports would be "this post is flagged as inappropriate"? ]]
1747 // [[ bruml: consistent terminology needed ]]
1749 // Posts and comments can be made anonymously. When a post is anonymous, the users info is stripped
1750 // from the post and the userName is set to Anonymous and the userAffil to N/A. This is to allow
1751 // users the ability to make posts or comments that they might not otherwise due to not wanting
1752 // the content of the post/comment to be attributed to them.
1754 // Each time a user connects to the server, it passes through authorization which checks for a cookie
1755 // that is set by Express. If a session exists and it is for a valid logged in user, then handshake.user
1756 // is set to the users data, otherwise it is set to false. handshake.user is used later on to check if a
1757 // user is logged in, and if so display information that otherwise might not be visible to them if they
1758 // aren't apart of a particular school.
1760 // After the authorization step, the client browser sends the lecture id which is rendered into the html
1761 // page on page load from Express. This is then used to assign a 'room' for the user which is grouped
1762 // by lecture. All posts are grouped by lecture, and only exist for that lecture. After the user is
1763 // grouped into a 'room', they are sent a payload of all existing posts for that lecture, which are then
1764 // rendered in the browser.
1766 // Everything else from this point on is handled in an event form and requires a user initiating it. The
1767 // events are as follows.
1770 // A user makes a new post. A payload of data containing the post and lecture id is sent to the server.
1771 // The server recieves the data, assembles a new post object for the database and then fills it with
1772 // the appropriate data. If a user selected for the post to be anonymous, the userName and userAffil are
1773 // replaced. If the user chose for the post to be private, then public will be set to false and it
1774 // will be filtered from being sent to users not logged into and not having access to the school. Once
1775 // the post has been created and saved into the database, it is sent to all connected users to that
1776 // particular lecture, unless it is private, than only logged in users will get it.
1779 // A user votes for a post. A payload of data containing the post id and lecture id are sent along with
1780 // the user id. A new vote is created by first fetching the parent post, then adding the user id to the
1781 // votes array, and then the post is subsequently saved back to the database and sent to all connected
1782 // users unless the post is private, which then it will be only sent to logged in users.
1785 // Similar to the vote event, reports are sent as a payload of a post id, lecture id, and user id, which
1786 // are then used to fetch the parent post, add the user id to the reports array, and then saved to the db.
1787 // Then the report is sent out to all connected users unless it is a private post, which will be only sent
1788 // to logged in users. On the client, once a post has more two (2) or more reports, it will be moved to the
1789 // bottom of the interface.
1792 // A user posts a comment to a post. A payload of data containing the post id, lecture id, comment body,
1793 // user name, and user affiliation are sent to the server, which are then used to find the parent post
1794 // and then a new comment object is assembled. When new comments are made, it updates the posts date
1795 // which allows the post to be sorted by date and the posts with the freshest comments would be pushed
1796 // to the top of the interface. The comment can be anonymous, which then will have the user
1797 // name and affiliation stripped before saving to the database. The comment then will be sent out to all
1798 // connected users unless the post is private, then only logged in users will recieve the comment.
