apd VS centrifuge

https://github.com/cockroachdb/apd is currently the best implementation in the ecosystem (performance, correctness). Have you already evaluated it?

FWIW I think cockroachdb/apd is the best third party option. While building bojanz/currency I've evaluated and benchmarked the others and found them either less maintained, slower, or both.

I have a package for handling currency amounts and calculations that is based on cockroachdb/apd, in my opinion the best arbitrary-precision decimal implementation in Go right now. So, I can offer a bit of insight.

The best decimal package is still cockroachdb/apd. I wrap it in bojanz/currency for money handling.

https://github.com/cockroachdb/apd remains the best decimal library for Go (ericlagergren/decimal is faster but unmaintained).

Note: In benchmarks ericlagergren/decimal was noticeably faster than cockroachdb/apd, but it has known bugs when used with go mod, so I decided to wait and go with cockroachdb/apd for now. The Amount struct wraps the decimal implementation completely, making it easy to do the swap later without breaking BC.

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

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

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.
