ws VS centrifuge

Then take a look at this article - https://www.freecodecamp.org/news/million-websockets-and-go-cc58418460bb/ - using external from Go std lib epoll implementation and https://github.com/gobwas/ws lib it's possible to reduce memory usage per connection drastically. Though keep in mind that this approach is not obvious to implement right and you better to go with STD lib.

Yes, but there are two excelent libs for golang websockets - https://github.com/gobwas/ws - https://github.com/centrifugal/centrifuge

Yes, I find https://github.com/gobwas/ws to be far superior. It has a lot more ability to customize and get high performance as well as a utility package that is much higher level and makes it easy to use. It doesn't have some of the problems of gorilla because they didn't have to support people already depending on it

There's https://github.com/gobwas/ws and https://github.com/nhooyr/websocket but neither have seen a commit in over a year

Oh, thanks! And sorry for still not switching to https://github.com/gobwas/ws :)

Hello, +1 to WebSockets. If you need to choose WS library – go with https://github.com/gorilla/websocket or https://github.com/gobwas/ws. You can also look at Centrifugo server (https://centrifugal.dev/, supports WebSocket, SockJS bidi transports, also EventSource, HTTP-streaming, GRPC unidirectional transports and many builtin features) or https://github.com/centrifugal/centrifuge Go library.

I prefer gobwas/ws because it has the high level "easy mode" (though some things will still be a small learning curve if you are used to REST mostly) and a low level API that you can dive into if you need very high performance and don't mind getting deeply into the details. It has the advantage of being written much after the most popular Gorilla websocket implementation which has some complexity and other issues that it can't totally remove in order to keep compatibility for all of its many users. It's also battle-tested via mail.ru. See A Million Websocket and Go for more details on its inception.

BTW, Centrifugo is based on https://github.com/centrifugal/centrifuge Go library which may provide much more control and flexibility for Gophers than a standalone server and can be embedded to any Go app leveraging all Centrifugo client SDKs.

There are libraries which provide more advanced APIs for creating real-time applications, for example https://github.com/centrifugal/centrifuge

What https://github.com/centrifugal/centrifuge does:

Have you considered https://github.com/centrifugal/centrifuge? It also uses Gorilla WebSocket for WebSocket transport at the moment – but it's hidden inside and may be replaced if needed since Transport interface is pluggable. It's more heavyweight though than both Melody and Gorilla WebSocket but provides much more functionality out-of-the-box.

Not a Socket.IO compatible but maybe you will find it useful/interesting: https://github.com/centrifugal/centrifuge

Thanks! BTW, Centrifugo's core is based on https://github.com/centrifugal/centrifuge Go library - which theoretically can be more flexible and extensible solution for Go developers than Centrifugo server since server dictates some auth/permission/channel/api rules.
