emitting to server but not text area about flask-socketio-chat

[miguelgrinberg]

The "Received packet" log message is put out by the server. The text area where you expect the messages to appear is in the client, so you are not providing enough information to diagnose this problem.

The way this goes is more or less like this: A client types something and presses the submit button. That triggers an event from that client to the server. This corresponds to the log message that you copied above. For the message to appear to all the other connected clients, the server must have a handler for the event named "text", and in this handler an event must be emitted back to all clients. Then, when the clients receive the event they have to manipulate the DOM to make the text appear in the text area.

So you need to trace the path the data takes a bit more to find what part is broken.
