hi there !
i checked out codes but im a beginner and i wasnt able to understand that well .
so i have a question " Does it work over internet? behind nat? different routers?"
if not how to configure that to work ?
Thanks !

https://cdnjs.cloudflare.com/ajax/libs/peerjs/0.3.18/peer.min.js doesn't seem to exist on cloudflare?

I'm running latest firefox and going to the resource directly gives me a 404. 0.3.16 seems to load fine.

I found peerjs able to connect but not able to send data to other peers.
here i am only include mobile related issues. It's working pretty good at laptops, pc.

Hi the demo isn't working since the peerserver couldn't be connected.

the demo currently only allows single sender and single reciever , is it possible to connect multiple peers to this? i.e the sender can signal to say 100 receivers ?

Unfortunately the demo currently does not work. Since the demo website is not using TLS, the user will get a CORS policy error:

Failed to load resource: the server responded with a status of 504 () receive.html:1 Access to XMLHttpRequest at 'https://0.peerjs.com/peerjs/id?ts=15438508918090.3806686527050229' from origin 'http://jackmckernan.tk' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I guess there are two solutions to this:

1. Add a certificate to the website and serve it via https (preferred) or
2. Add secure: false to the new Peer()call

hi, cool system.
I tried to run the demo on Chrome (latest) in MacOS and was not successful (even though the same works on Safari and Firefox).
The problem was that the sender issues a peer connect command, server receives the command (and thought it is connected). but the sender never saw that the connection was established and get stuck there.

after making successful connect, On sender.html send button is not working. Even i try to log the event sendButton.onclick but no log is showing.

One https://peerjs.com/examples.html

The example link goes to:
http://jackmckernan.tk/open-development/peer-to-peer-cue-system/

Following this link takes me to a page that attempts to get me to install an extension. Seems pretty fishy.

Peer ID is not generating suddenly from yesterday itself and this example is not working.

Hello

Is it possible to send data with PHP?

Thanks

when we try on different laptop that is hosted in a local server there is a media issue

Because this system was only designed for a single active pair of users, the identifiers used for inital connection and handshake are hand-assigned. For a multi-user system, this would need to be adapted to generate random ids that could be communicated prior to inital connection. This could be achieved through a centralized database (i.e. username linked with a randomly generated key at each login), any pre-existing two-way communication protocol, or simply with local generation and instructions to communicate to the second party. For ideas and implementation, take a look at this.

Should either identifier indicate that it is already in use, nothing can be done until the hold should expires on the server within two days or so. In this projects current state and with only a single active pair of users, the only option to rectify this is to manually change the indentifiers on both the sending and recieving page.

This error is especially prevalent when one user momentarily loses network connection. PeerJS (handles indentifier pool and initial handshake before dropping to direct peer-to-peer) has documentation suggesting a method to recover from this. At the time that this project was under active development, however, this method was unsuccessful at restoring connection or removing the "in use" status of the identifier on the PeerJS servers. There were several reports that error was on PeerJS's end of things. The PeerJS Repository no longer appears to be under active development, so chances this issue will not be resolved by them.

TypeError: Attempted to assign to readonly property.

I think you went overboard.
Sorry, about what I have to say.

I've been trying to decorticate your code for hours.
Why so much repetitions? This not coding. Never repeat, write once and reuse.
That's beside the useless one. You don't need a function to just return {};
Use a global if you have to.
And why does it loose connection every 5 mins?

All I need, is just this, sending small amount of data between web page in browsers.
I'm not gonna 9000+ lines of code for that.
I have made an entire Video and cache processor in less than 1200 JS lines.
Can't you make something simpler? So I can figure out what needs to be done (Easily).
Unless, that was your intend. In that case, You know what that makes you.

Here, give you an idea how this is done:
Replace your "EventEmitter" with a real event object.
Notice that you may pass as many parameters as you want.
Beside I think it is more useful in the event handler than the trigger.
But, If it must be; the correct way would be "TheseParameters.details" as an object passed through the event.
You could have an object handler Handling the extra argument in the handleEvent of the object.
You don't need: emit(event, a1, a2, a3, a4, a5)
Just use emit(event, ...args)

Working locally but not across network
Maybe the peerjs server is having trouble today?

Steps to reproduce:

1. take you mobile phone and ensure you are connected using operator, e.g. 4G network, and not local network
2. open browser on our mobile, make it as receiver, so visit https://jmcker.github.io/Peer-to-Peer-Cue-System/receive.html
3. PC: open browser on your PC, make it as sender, so visit https://jmcker.github.io/Peer-to-Peer-Cue-System/send.html
4. PC: type proper ID from receiver part and finish connection
5. PC: try to send some message

Expected result: the chat is working, you can send and read messages
Current result: it works only if receiver and sender are on the same or nearby network

The issue is very probably caused by TURN/STUN server.

is it peer to peer cue system capability of
having a voice chat each other?
While the 2 laptops connected on different wifi networks?
