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

[@tylerpetrov8094]

Thanks for the vid! Definitely just what I needed to get up and running!

Thanks for clutching my school project

[@abhishekkandari7116]

Thank you for the tutorial.. will try this

[@annedou7567]

Thanks for the amazing video

[@markogrdinic5126]

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.

This is awesome! Great video

[@alexzakr]

It's so cool!

[@morshedulislamriaad6496]

ThankYou

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.'

[@prototypebharrat]

Yaa same problem.my app work in development environment but not in deployment

[@WaldoTheWombat]

@@prototypebharrat were you able to solve it?

[@itwasnoteasy]

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?

[@WaldoTheWombat]

hello, were you able to deploy it?

[@itwasnoteasy]

Yes, I switched to using flask socketio for my project purposes.

[@WaldoTheWombat]

@@itwasnoteasy what do you mean you switced to flask socket-io? That's flask socket-io is what's shown here

[@itwasnoteasy]

@WaldoTheWombat - that’s right I was trying to use flask-sock earlier and switched to flask-socketio. Then I installed gevent or eventlet to start the server. It worked fine over https. I don’t recollect the exact steps but it just worked fine. Part of the problem was to figure the exact command line for gunicorn and gevent/eventlet combination.

[@WaldoTheWombat]

​@@itwasnoteasy Could you *please* tell me how to do it?? I've watched both Tech With Tim's and Corey Schafer's tutorials on how to deploy Flask apps, but it doesn't work for web sockets.
I get:
'Cannot obtain socket from WSGI environment.'
I have no idea how to solve this and non of these tutorials really explain what how all these server programs work.

[@LoVe-iu9rd]

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

[@geovannis.a8687]

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

[@LoVe-iu9rd]

How did you deployed it to production?

[@robbedeboosere589]

does anyone have instructions for this?

[@GLBCHAT]

@@robbedeboosere589 I struggled with deploying for 3 days , then I could successfully deploy my app to heroku! Should I make a video about it?

[@WaldoTheWombat]

were you able do deploy it?

[@amanavakn205]

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.

[@cauefernandes5706]

I downloaded the source code, but it doesn't work anymore.

[@jenshauser6351]

haven't you allready uploaded that topic a while ago ? 🙂gonna check it :D

[@prettyprinted]

Yeah I did about 6 years ago. I wanted to make an updated video.

[@Franklin096]

Python version?

How to do with django rest framework?

[@prettyprinted]

How would you use sockets in an API app?

[@famisalpedo]

how to add videocall

[@chks_charles]

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

[@learnmore5438]

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

[@prettyprinted]

You'll have the easiest time by deploying to your own server instead of using a service. Look into something like Lightsail or Digital Ocean droplets.

[@learnmore5438]

@@prettyprinted thank you, i just deployed it btw.

[@WaldoTheWombat]

@@learnmore5438 can you please tell me ho you did it?

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

[@en_coded]

why is it not realistic to place in one file?

[@codedjango]

With django?

[@prettyprinted]

I'll consider making something similar in Django.

[@codedjango]

Thank you 👍

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