- socket takes care of modifying the username in the forked socket
session and sending a status message to chat window
- ajax request takes care of updating the flask session so that on
refresh or re-opening of the URL in same browser, the username remains
same
- Disabled till username not changed
- On change, if username is empty, then disabled
- On change, if username is changed back to previous, then disabled
- Else allow saving
- Refactors server side code to use instance variable instead of
background thread to generate a list of connected users
- Send this user list anytime any change is made to the list. It can
be: join, update username, disconnect
- In js, render the entire user list everytime it is received.
- Scroll to the bottom of the chat, everytime the current user
sends a message
- Else, if already at the bottom of the chat, scroll to the bottom
after appending incoming status or chat message. But if the user
is scrolled up in the chat window, then do not scroll to the bottom
- When refreshed or close tab is clicked, default browser warning is
shown.
- On receiving disconnect, the browser removes user from room.
- If refreshed, it is shown as if the user left and joined again.
- allows users to update their username and save the new username
- runs a background thread for every user session which emits a
broadcast with the username so every user can build their list of
active users in the frontend via the socket information
- on updating username, stop the old thread and start a new thread
with the new username being emitted. The username is updated in
everyone's list along with a status message for the same.
