Chat-Room | A 1v1 Video Chatting application using Python3 sockets | Socket library

PROBLEM SUMMARY

My goal is to use an iOS app written in SwiftUI to connect with AgoraRtcEngineKit. I want to create an app that is audio-only and allows a host to broadcast audio and allows listeners to listen in.

The use of tokens is required by Agora.

I created an Agora Token Server using Node.js based on Agora's tutorial found here: https://www.agora.io/en/blog/how-to-build-a-token-server-for-agora-applications-using-nodejs/

Here is my index.js from my Agora-Node-TokenServer. This code is based on the Agora tutorial found here: https://github.com/digitallysavvy/Agora-Node-TokenServer/blob/master/index.js

I am trying to create chat room instance in database. I need to catch an error when room with two similar users is creating. Here is my chat-room models.py:

I'm making chat-app. If i click chat-room , i want to change all chat [{ ..., read: false => ..., read:true }]

I am making a chat-application where there are 2 pages. One page shows you default available chat-rooms in the select dropdown tag and the other allows you to make your own room.

What I am willing to do is to add the custom-room's name to the select-dropdown tag. I have tried to appendChild the room's name to select tag but it shows "Uncaught TypeError: Cannot read property 'appendChild' of null". Can anyone give me any suggestions to help me out? Thanks for the read! Appreciate it...

I am trying to implement sign-in based on Google OAuth2. Couldnt figure out the problem.

I am working on a desktop chat app using electron. In order to make the chat-room work, I have to configure the websockets. My problem is that I dont know what I should put in the const ws = new WebSocket("ws://129.0.0.1:5000"); I tried many things but I always get errors like

failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT

This is the renderer

Problem:

I am working on a chat application. When I send more than 9-10 requests, the browser slows down and eventually, it just hangs. On refreshing the page, everything is back to normal. I searched the socket.io documentation but couldn't get any solution regarding this matter.

Code:

Here is my Backend Express.JS code:

This question is very similar to This question

I have set up a Vue page with Laravel and showing all posts with a help of a GET request. I am also listening to a Laravel ECHO event and unshifting the value to the all posts array making it appear on top.

I have set up the infinite scroll and paginating 5 results per page using this package. Results appear on the page and pushing to the array from the listener also works. However, when infinite scroll loads the 2nd results page, the 6th result is duplicated.

The aforementioned package accepts next_cursor an offset value as the parameter instead of page=2 so it exactly loads the value without any duplications.

Controller.php

I want to send messages from nodejs backend to the specified websocket channel. So I want to implement/use similar function like convertAndSend function on the spring SimpMessagingTemplate.

I try to implement this with ws lib, but the send function only has two parameter: message & callback and I cannot specify the message destination. Here is a brief example from backend code:
