kandi X-RAY | socketio Summary
A copy of github.com/googollee/go-socket.io renamed with defects fixed and updated to 1.4.5 of socket.io. Updated to work with socket.io version 2.3.0 and jQuery 3.5.1. socketio is an implementation of socket.io in Go (golang). This provides the ability to perform real time communication from a browser to a server and back. Content can be pushed from the server out to the browser. It is compatible with the 2.3.0 version of socket.io in Node.js, and supports room and namespace.

QUESTION
I'm trying to make a simple script to push events from a python app to a client. I made a Console React component, which uses SocketIO to receive the events, and I'm pushing the messages with Flask SocketIO.
This is my app.py:
ANSWER
Answered 2021-Jun-14 at 00:58I solved it following @Miguel's comment.
Long story short, the useEffect() function is executing on every render, and every time it executes it adds a new handler without deleting the previous one, so after a few renders things get out of control exponentially. So I just added a line to delete the handler when it finishes.
QUESTION
im trying to create a simple app with a login just to play around with socketio, vue and nodejs (express), i got the sending and receiving to work on both the client and the server. But i got a problem when i try to integrate a session so i can keep a user logged in.
i tried many different modules nothing worked for me. I'm sure that there is just something i am not getting right now, since i'm pretty new to nodejs and all that.
anyway here is my code:

I am having the same issue as this thread: Reflecting tables with Flask-SQLAlchemy raises RuntimeError: application not registered I tried adding:
...ANSWER
Answered 2021-Jun-10 at 08:24The issue is that the app tries to go through the reflection classes without being fully loaded, so sqlalchemy gets an error due to not finding the currently running app and raises RuntimeError. I found that to fix that you need to provide app_context and therefore this fixed my issue.
I changed my app file to:
QUESTION
I am trying to create a room and get the output on the client side through the emit, but it doesn't seem to work.
can you please tell me what's wrong with it.
I think this is the error but I can't figure out what it means:-
participants = ns[room[0]]._fwdm.copy() if room[0] in ns else {} TypeError: 'int' object is not subscriptable
File "E:\KabirProject\WebsocketDocs\app.py", line 36, in join_roomm emit('room joined', "Heyy I've joined the room", to = room)
here are my server side codes:-

Answered 2021-Jun-09 at 18:15This happened because I was trying to pass an integer in the to parameter and I think it only accepts string so when I started passing string It started working.

We really tried a lot but it still can not get the Symfony RabbitMQ bundle (https://github.com/php-amqplib/RabbitMqBundle) running in AWS (with Docker). AWS only allows AMQPS and port 5671 to be opened in the AWS managed service.
This is our current configuration in detail:

Answered 2021-Jun-09 at 09:33Finally solved - you have to define a custom AMQPChannel with a custom AMQPConnection with SSL options and then set this AMQPChannel to the producer:
QUESTION
I'm having issues with Node SocketIo client not emitting data. So when the client connects in the index.html does log the "Connected This Is A Test", however it does not socket.emit('cool'), no errors nor does it seem to log on server.js. I'm not sure why its not emitting or the server isnt listening.
Server.js
...ANSWER
Answered 2021-Jun-08 at 03:12On your server, you need to be listening for the cool message on a specific connected socket, not on the io object. The io object does not have specific socket messages other than announcing a newly connected socket. To listen for messages from a specific socket, you need a listener on the connected socket itself. The usual place to add that listener is in the connection event where you are presented with the newly connected socket object.
So change this:
QUESTION
I used flask-socketio to implement websocket. I used the eventlet/socketio sleep() function, which supposed to work asynchronously. And this is working in my custom event but when it is under the connect event, it is not working. Here is the reproducible code:
Backend code:
...ANSWER
Answered 2021-Jun-06 at 09:25The connect event handler is supposed to be used only to decide if a client connection is accepted or rejected. It has to run quickly, because the connection isn't fully established until the connect handler returns.
Move your logic to a normal event, and just use the connect handler for authentication/authorization purposes.
QUESTION
I couldn't understand which version of socketio-java-client is compatible with flask-socketio server.
Whether I have to check the version of socketio-java-client version with the flask-socketio or python-socketio or to the python-engineio versions?
...ANSWER
Answered 2021-Jun-05 at 18:31The Python Socket.IO documentation only tracks compatibility information against the JavaScript reference implementation and with the protocol version numbers. Unfortunately I do not have the time to test and update a compatibility table for every Socket.IO implementation that is out there.
What you need to do is find out with what version of the JavaScript reference implementation your Java client aligns with.
Or if you prefer, you can just test things out until it works. For the Python Socket.IO there are really two major versions that you need to test out.
First, try the latest one:
QUESTION
So, I have opened windows in pywebview at a time. Now from window 1, I want to click a button and show some texts in window 2. How can communicate between them? I was thinking of using flask-socketio or any socket based solution. But that seems like overkill for this, is it? How can this be easily achieved?
This is the code to open multiple windows in pywebview:
...ANSWER
Answered 2021-Jun-05 at 04:31Well, in the end, I had to go with the hard way (though it was easy), the socket way. I used flask-socketio to implement this feature. Here is an example:
Suppose I have 2 separate windows, Window_1, and Window_2. Now I have a button in Window_1, from where I will click a button and a pop-up will show in Window_2.
