Direct Message a fellow User

Your direct messages with someone are private, and can not be accessed by anyone else. In order to test this, feel free to chat with bot from the user list.

Explore

Chat feature in Alexandria shows the timestamp of the message, along with the userName and avatar (profile picture) of the message sender (as obtained from their Google Account).

You can also start a meeting from here, which will redirect you to the Meeting UI. Any messages exchanged in a meet call shall come up as Meeting Logs in the Chat UI itself after meeting conclusion.

When on the DirectMessage UI, note the ID string in the URl. This ID is unique to just you and whoever you're chatting with (I call this a pairID ); I use this ID to store messages and handle events common to just the two of you (like starting a call)

Working

• All messages are stored as documents under collection dms\<pairID>\messages\.

• The pairID for two users is obtained by taking a substring from each user's uid, converting both ascii strings to Hexa separately and then summing them.

    function ascii_to_hexa(str) {
    var arr1 = [];
    for (var n = 0, l = str.length; n < l; n++) {
    var hex = Number(str.charCodeAt(n)).toString(16);
    arr1.push(hex);
    }
    return parseInt(arr1.join(""), 16);
    }
  

Troubleshooting

• If Call Logs do not show up after a meeting conclusion, please try again.
