At 21:57, instead of using the username as the key for the dictionary, it would have been better to swap the two and use the sid instead. Then you wouldn't need to loop over the dictionary and instead could directly index into it using the sid to get the user data.

Thanks for clutching my school project

Very very nice the video and the code. I will use it like a good example for a my game project. Thanks 🤙

How did you deployed it to production?

[WaldoTheWombat]

Hi Anthony, do you also have a video where you deploy a flask app that uses web sockets? because I just finished deploying my app watching a deployment tutorial by Tech with Tim, but it seems that the sockets don't work there:

'Cannot obtain socket from WSGI environment.'

Thanks for making the video. Have you deployed flask-socketio over ssl with wss etc on aws or any other cloud instance in a production like environment?

I am getting a 400 (Bad Request) error when trying to connect with the postman. Any idea what is going wrong? BTW video is very informative.

Thanks for the Video. Do you know a way to create a multi-chat on the same page? Or do you know a web tool to do that?. Is only a cultural question.. haha

How about pushing notifications to this message as well rooms sessions, please make a video.

Tell me where i am wrong:
1) useless setting autoconncet to false, your explonation contradicts the idea of ws. after handshake you can pass this name same way - and even you said it when moved to messages. this is useless in this aplicaion?
for instance:
var socket = io();
socket.on('connect', function() {
socket.emit('name', {data: 'Donald Duck'});
});
whats the point of disabling autoConnection here? btw -code above is right from documentation....

2) why dont you use rooms? sending message to server to emit it back to other users - why? You connect users give them room, and they emit to the room....
this contradicts one of advantages of socketIO as layer on websocet - handling many clinets via rooms...

peace

why is it not realistic to place in one file?

[Kennethlumor]

Please I'm pleading you to make a video on how to connect Google Oath to flask login, that will make users registered with the Google account before signing in

[learnmore]

does anyone knows how to deploy this on live production server?

[Kennethlumor]

Sir please and please I just wanted to remind you again about my request on this
