WebSocket compression is enabled in some browsers by default (at the time of writing for example in Chrome, but not in Firefox). The client has to include the ‘Sec-WebSocket-Extensions: permessage-deflate’ header for this. If the server responds with the same extension, the WebSocket communication is compressed on a frame basis. As far as I know, … Read more
WebRTC is designed for high-performance, high quality communication of video, audio and arbitrary data. In other words, for apps exactly like what you describe. WebRTC apps need a service via which they can exchange network and media metadata, a process known as signaling. However, once signaling has taken place, video/audio/data is streamed directly between clients, … Read more

Main use case of the load balancer is to distribute the load among node in a group of the server to manage the resource utilisation of each node One of the use cases of a reverse proxy is to hide server meta information (ip,port etc..) from … Read more
Quite an old question I’ve asked, so I’d be happy to share our chosen practice: Once the client gets his JWT for the first time (when the application starts), a WebSocket is opened. To authenticate the channel, we send a message that we define as part of our protocol, called authMessage which contains that JWT. … Read more
No, websockets is only natively supported by Windows in Windows 8, regardless of which visual studio version you are using. http://www.paulbatum.com/2011/09/getting-started-with-websockets-in.html This is due to some low level issues in Windows 7 with http.sys. There’s an offchance it may be backported, but seems unlikely: http://weblogs.asp.net/owscott/archive/2012/03/01/what-s-new-in-iis-8.aspx To use websockets on Windows 7, you’ll have to write … Read more
I know you asked a while ago, but the information remains for those who are researching. I did an analysis with reverse engineering in version 2.3.0 (socket.io) and 3.4.2 (engine.io) and got the following: The first number is the type of communication for engine.io, using the enumerator: Key Value 0 “open” 1 “close” 2 “ping” … Read more
Have you looked at Primus? It offers the cookie requirements you mention, it supports all of the major ‘real-time’/websocket libraries available and is a pretty active project. To me it also sounds like vendor lock-in could be a concern for you and Primus would address that. The fact that it uses a plugin system should … Read more
What is RSocket? RSocket implements the Reactive Streams specification over the network boundary. It is an application-level communication protocol with framing, session resumption, and backpressure built-in that works over the network. RSocket is transport agnostic. RSocket can be run over Websockets, TCP, HTTP/2, and Aeron. How does RSocket differ from Websockets? Websockets do not provide … Read more
It seems to be possible using swagger-socket. Still, it seems that only a Java/Scala server implementation exists for now, which means they are not as much codegens for this that there is for “standard” Swagger REST services. Edit: As pointed out, this project seems to be dead. Unfortunately at the time of updating this answer, … Read more
