SocketIO in Flask and Javascript

Creating a chat app which provides both personal and group chat option using Flask SocketIO and also dislplaying the details of available clients inside a table.

Sid in flask can be used inside emit method to identify any client. Thus when parameter room=request.sid is passed inside the emit function, the message is only sent to the particular client.

Note: Client can only send data to Server and not to anyother client.
