I really like your presentation style. No attempt at humour or to be entertaining just explaining clearly what is on the screen. Thanks!!

Love your video as u cleared my doubt regarding socket...before ur video socket was nightmare but now it is like piece of cake.

Is it possible to upload files using SocketIO File Upload (siofu) from a JS client to a Python server? any recommendations on where to find information on that subject?

[@beautybeast865]

Hi sir.. I'm using django in a container. I would like to know how can I set my workers more than 1.. or should i make another container to serve my django app for using 4 workers.. if i do that my nginx can't see my socket connections.

On windows? Try inside the WSL, gunicorn does not run natively on that OS

Thanks for the helpful/awesome tutorial Miguel! In part 8: Authentication, I was not able to set a username in the Firefox browser. The username keeps resulting to None. Any tips on what I should be looking at?

I figured it out, I never added the transport Options on my client

[@rohitkatkar3736]

Hello, Is it possible to have server streaming using socket io in python?

[@rohitkatkar3736]

Meaning: One request from client and multiple response from server.

[@miguelgrinberg]

@@rohitkatkar3736 yes, of course.

[@rohitkatkar3736]

Thanks for quick response. Could you please tell me how?

[@miguelgrinberg]

@@rohitkatkar3736 There are no requests or responses. The server or the client can send to the other side whenever they want.

[@rohitkatkar3736]

Thanks alot. I will try again. Thanks.♥️

Can you tell me can I user python-socketio for real company projects or channels??

[@LeeanRepzTraining]

amazing video man!!! could you possibly do a video with these two together socket io/ python + javascript for a friend request scenorio along with database

[@smithchristian4251]

I am using RPI as my client and taking many sensor reading every second, but I am confuse if I should use async functionality or regular functionality? Also i am using eventlet in my server. Second question: is it okay if client.py use async functionality but server.py doesn't can they still communicate fine?

[@miguelgrinberg]

You should use sync Python if your hardware I/O library is sync, or async if your I/O library is async. The problem occurs when you mix different modes. The server can be sync or async, doesn't matter.

Sir please show us that how to deploy flask application with flask-socket.io , gunicorn and nginx

[@elbajadourvillacampa5149]

Is it possible to just start the server in a specific host and port and allow html pages to connect to it. I am currently making a web app using Laravel Vue and the data will be emitted from a Python Application. I'm wondering if is possible? Thank You

[@miguelgrinberg]

Yes. This package does not care about that. You can configure your python web server to listen on any host and port.

[@Seanomarachain]

Vayas tus vacas son gordos. Thank you, you are a real clear communicator, and this was really interesting. Do you see the likes of web-sockets protocol replacing REST stateless communications? What do you think will happen? I actually think this type of event driven I/O is more natural. What sort of projects have you used this on?

[@miguelgrinberg]

HTTP and WebSocket do not compete, they have different use cases, so I do not expect either one to replace the other.

[@leamon9024]

Hi, if possible, could you do a tutorial about how to do load testing for this library by using tools like JMeter, locust...etc.?

[@mirrorinfinite5392]

Hi Miguel, on part 3 where we use gunicorn with eventlet, does this mean we are making our socket io server into an asynchronous server? Does one eventlet worker correspond to one thread meaning the server is single-threaded? From what I understand, the eventlet worker is an async worker which can spawn greenlet pseudo threads when a new request(eg new events) is received. Thank you for the tutorial!

[@miguelgrinberg]

A single eventlet worker can handle hundreds or even thousands of concurrent clients. And yes, it is asynchronous.

[@fersalamanca2606]

Hi Miguel! this tutorial is amazing. What would be the difference if I wanted to implement this inside a Flask server? I assume is mainly on the setup but appreciate any advice you could spare. Thanks in advance!

[@miguelgrinberg]

There is no difference. You can combine Socket.IO and any standard WSGI App (Flask, Django, etc) into a single server. The Flask-SocketIO extension integrates Socket.IO with Flask.

[@fersalamanca2606]

@@miguelgrinberg ok, so the only difference here is that you are setting up a pure socketio server and if I wanted to do it with flask, I’d have to use flask-socketio instead of py-socketio?

[@miguelgrinberg]

@@fersalamanca2606 correct.

sir iam making a strangers video calling platform like azar i was thinking to have backend python server and js client how can i do that imean how can i p2p using python and socketio

Sorry, but this is an extremely complex question that cannot be answered in a comment. You should learn more about p2p and mabe webrtc if you intend to implement something of this complexity.

Sir, thank you for the tutorials. By the way i interested your udemy course mega flask tutorial. Is it still works in 2021?

Yes, the course is still valid and up to date!

Thanks for the tutorial and you are always creating quality content. I do have a question. How to implement the following function with flask-socketio? Create two clients, a user and agent html files respectively. And a python flask server. Agent input message and send message to server then the message will show up in user client html.

[@rushibutley8477]

Thank you so much miguel ❤️, you’re gem. Your tutorials are awesome. Just request, It will be great if you can also add maybe part where tweaks we need to do to scale our python code. For example i had to tweak socket server library to run along side load balancers, to create lookup service and to do that i had to override few classes. Code can be looked here: github.com/rushi47/Threaded_Socket_Server It will be great if you can explain such advance concepts as well. Basically i learnt python from your tuts only but now am in situation lot of Times where I can’t look anywhere for any help.

[@miguelgrinberg]

There are many ways to deploy a highly available service, and this is largely unrelated to socket.io, so I don't believe it belongs in this course.

[@rushibutley8477]

@@miguelgrinberg Hey i was talking in general it didn’t need to be mention here, that was one of idea. It will be great if you can share your that experience as well maybe series on highly scaling services.
