A demo of using WebRTC with no signaling server.

serverless-webrtc

This is a tech demo of using WebRTC without a signaling server -- the WebRTC offer/answer exchange is performed manually by the users, for example via IM. This means that the app can run out of file:/// directly, without involving a web server. You can send text messages and files between peers.

This repository contains two different clients that can talk to each other:

1. serverless-webrtc.js runs under node.js
2. serverless-webrtc.html runs in Chrome or Firefox

Chat is fully interoperable between all of the above (Node, Chrome, Firefox) in any combination (tested with Chrome 35 and Firefox 29).

For Node:

 λ npm install serverless-webrtc
 λ node_modules/serverless-webrtc/serverless-webrtc.js

Under Node, if you want to create a session instead of joining one:

 λ node_modules/serverless-webrtc/serverless-webrtc.js --create

For browsers:

In Chrome (but not Firefox), you'll need to run a local web server rather than just browsing to file:///, like this:

 λ cd serverless-webrtc
 λ python -m SimpleHTTPServer 8001 .
Serving HTTP on 0.0.0.0 port 8001 ...

and then browse to http://localhost:8001/.

For Android:

Vojtěch Sázel has ported this project to Android: serverless-webrtc-android.

serverless-webrtc's Issues

Sending unparsed data to fileReceiver

When you are sending data to fileReceiver you are sending unparsed object "e.data" not json parsed "data" variable. File transfer doesn't work, because it is expecting json parsed object.

Any idea have I can fix it ? thx

Text only version?

I'm working on a text-only fork of this project.
Is there a way to create an offer without a stream object?

Unable to find native module

I am getting this error . UNABLE TO FIND NATIVE MODULE when I run it on Node Js

Does this work in a closed network (f.e. on a wifi network with no internet)?

Does this work in a closed network (f.e. on a wifi network with no internet)?

I'd like to connect two devices by running code in each device's browser. They are on the same network via WiFi, without internet.

Is this what can be done?

Progress bar for file transfers

Is it possible to get a progress callback in Firefox?

Chromium Works But Doesn't

If I open up the hosted demo it works just fine in Chromium. If I clone the git repo and open it locally, it doesn't work in Chromium but does work in Chrome. What's going on? I want to use this script in Electron.js. Why would it work locally in Chrome but not Chromium? I haven't tried it in Electron yet but I'm hoping it will work. I don't want to run a python script.

Is there some difference between the hosted demo and what's in the git repo?

Large file transfers fail

Large (>100KB) file transfers sometimes fail silently, sometimes hang the browser. I don't know why yet.

Move the code from master to gh-pages

Then mark the gh-pages branch as the "default" in your Github settings, and delete the master branch.

Same as before, but all of a sudden you'll have a demo URL to point to, at http://cjb.github.io/serverless-webrtc/serverless-webrtc.html.

Broken in Chrome on Windows - jquery and getUserMedia detection, and non https - PR in comments

jquery gets callstack exceeded because the previous modals are not "hide" before the next modal is "show".

getUserMedia in adaptor.js detection doesn't identify chrome... additionally.. if not in HTTPS, getUserMedia doesn't exist.. This can be trivially shimmed around, allowing the datachannel (chat) to work.

There is a loong delay between offer generation and the ICE server result.. 30 seconds or so each way on my setup.. Is this normal?.. would be cool if this was wrapped into a small library.

Cool project!

Here is a PR with what I had to break to get this to work on Chrome/Windows:
Had to force "hide" any open modals before "show" ing the next one, or jquery gets a stack overflow...
I fixed it for the host, but might not have for the client, but it all eventually works...

I'm trying to connect my phone (Meizu m3s, Android, latest Chrome) and my PC (Windows, latest Chrome). Both are connected to same wifi network. It doesn't matter if it's a local file or hosted page, the error appears anyway.

When I visit https://cjb.github.io/serverless-webrtc/serverless-webrtc.html with Chrome or Firefox, the offer block stays empty. Chrome's console says:

How to actually make it nice

Sending that text to my next door neighboor is just going to scare him out.
I wonder what are the ways we could do this (beyond QR codes)

Open for ideas:

• encode them into a gif..?
• base emoji (too long)
• ..?

Connection establishment fails

Hello!
I've tried to chat with a friend, but we weren't able to connect to each other.
We used the browser demo link with a Firefox Browser.
When we looked at the offer or answer string we could only detect our local IP addresses but not the public ones.
Shouldn't this be the public addresses?
It seems to be a problem related to the STUN server connection.
I've changed the url to "stun:stun.l.google.com:19302" to try another server, but it still didn't solve the problem...

Is someone facing the same problem or has some advices?

Thanks in advanced

Demo is not working

Jquery appears to throw an error an prevent supplanting the string that was the local offer leaving it empty. Here is the full console log

Doesn't work on Chrome

Chrome doesn't support "reliable" (TCP) datachannels yet, but that's not the only reason this app doesn't work in Chrome. It would be great to at least fix the other reasons.

How would you build other clients?

Sorry if this is out of the scope of this project but if I wanted to build say a C++ client using QT to connect to peers in their browser, how do I connect to the peers? What is the nodejs native client leveraging to be able to do that?

This demo is completely broken

There are unanswered pull requests

Not working in Firefox 38

potential XSS in chat log

i wasn't able to test this because the demo is broken, but https://github.com/cjb/serverless-webrtc/blob/master/js/serverless-webrtc.js#L314 injects messages as HTML without escaping. so if alice sends <script>alert('hi')</script> to bob in the chat log, it may get executed in bob's browser (https://github.com/cjb/serverless-webrtc/blob/master/js/serverless-webrtc.js#L146)

Backdrop doesn't disappear when joiner "OKs" answer first

Running from file:///

If the person joining clicks "OK, I sent it" on the offer (2nd) dialog box before the creator clicks "OK, I pasted it", the backdrop doesn't disappear even though the connection is made and everything works. If I manually remove the

from the browser developer tools, everything still works.

Cannot create or join room

Hello,

I am trying out serverless-webrtc. I clone repo and try it out in browser (chrome 53, firefox 49b) and with node.js. I also try live demo and get same errors.

In node.js if I try to create room I get: "Invalid call to createOffer - function must either have prototype ([config]) or (successCallback, failureCallback, [config])."

In node.js if I try to join: "Unexpected token H in JSON at position 0"

In html if I try to create offer it doesn't work and same error as with Node.js: "Uncaught SyntaxError: Unexpected token H in JSON at position 0"

In html if I try to join the room I get error: "Uncaught SyntaxError: Unexpected token H in JSON at position 0 (anonymous function) @ serverless-webrtc.js:62dispatch"

Am I missing something or why is it not working?

*EDIT:
I guess I have to have a web camera to work properly. :) I am getting this error: "Error adding stream to pc1: [object NavigatorUserMediaError]"

Is it possible to work without web camera?
