socket.io-stream | Stream for Socket.IO | Socket library

I'm currently developing an application to stream video feed from client to server in NodeJS. The server side code is as shown below

server.js

I use RequireJS to load some scripts.

Now I would like to create some own methods which also needs the loaded script. I've tried a lot but I always get Uncaught (in promise) ReferenceError: hd is not defined. Both scripts are loaded in my index.html.

Calling the method 'connect' from main.js

I created a web app to let people communicate. I want to implement screen sharing and audio calls.

My current app is programmed in NodeJs and uses express and socket.io to serve the client connection and open a socket connection. I want to stream video and audio. My problem with WebRTC is that all those who connect to a call are vulnerable to a DDoS attack since it is p2p. I found an article from Discord explaining how they managed to let the entire traffic go through their servers: https://blog.discord.com/how-discord-handles-two-and-half-million-concurrent-voice-users-using-webrtc-ce01c3187429, that's exactly what I want to achieve.

Could I possibly use socket.io-stream https://www.npmjs.com/package/socket.io-stream ? I didn't yet figure out how, and it seems like all socket.io streaming libraries are made for file upload/download, not for actual video/audio streaming.

If that doesn't work, a library such as what Discord managed to make would be the perfect solution, since all traffic is proxied, and not p2p. Though I couldn't find any of those libraries, maybe I'm just looking for the wrong thing? Best regards

I am capturing data in the browser at about 15 fps that I would like to stream to my server. Right now this is just a single float var (distance). I am using socket.io-stream & socket.io to communicate between server and client. Basic io.emit() and io.on() events are working, but I can't for the life of me figure out how to stream a single var--I have even tried converting the single float to a Blob(), and ArrayBuffer, but I cannot see the data update on the server.

Here is my frontend code:

I make a simple audio recording web app using Firebase Hosting. I would like to record audio on browser and upload it to Cloud Storage. When I deploy and access my app, I can record audio. However the app failed to upload the audio to Cloud Storage.

(I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )

This is an error message in browser's console.

I need to build a new version of a javascript Node.js app. I have the source code and the macOS and Windows installers for the previous version of the app.

How can I find what version of Node.js was used to build the previous version of the app, so I can use the same Node.js version to build my new version of the app?

I understand that version of Node.js could have been different when building the macOS version and the Windows version. Ideally, I'd like to know what version of Node.js was used for each platform, but if I can get at least one that would be sufficient for my needs.

UPDATE: package.json:

I am trying to play wav raw data in the browser, which is transmitted from the nodejs server via socket.io, the main idea is to play the receiving data as soon as posible, so I don't need to wait until receiving data is done. I tried to use blob for this case, but next thing always happens: if I've got a chunk of raw data and I am converting it with blob for playing, then when the second chunk is ready and being converted with blob again, then while playing the audio breaks up for a while.

Also I was trying to use the code below and it's worked, but I could hear a lot of noises while playing it. Can anyone, please, help me with this problem and tell me how can I play audio without noises?

P.S. the timeout in the transmitting is a part of the main idea, I tried playing music without it, but still no luck.
