v5.1.0
Centrifugo is an open-source scalable real-time messaging server. Centrifugo can instantly deliver messages to application online users connected over supported transports (WebSocket, HTTP-streaming, SSE/EventSource, GRPC, SockJS, WebTransport). Centrifugo has the concept of a channel – so it's a user-facing PUB/SUB server.
Centrifugo is language-agnostic and can be used to build chat apps, live comments, multiplayer games, real-time data visualizations, collaborative tools, etc. in combination with any backend. It is well suited for modern architectures and allows decoupling the business logic from the real-time transport layer.
Several official client SDKs for browser and mobile development wrap the bidirectional protocol. In addition, Centrifugo supports a unidirectional approach for simple use cases with no SDK dependency.
For details, go to the Centrifugo documentation site.
What's changed
Improvements
- Support for EC keys in JWK sets and EC JWTs when using JWKS #720 by @shaunco, JWKS docs updated
- Experimental GRPC proxy subscription streams #722 - this is like Websocketd but on network steroids 🔥. Streaming request semantics - both unidirectional and bidirectional – is now super-simple to achieve with Centrifugo and GRPC. See additional details about motivation, design, scalability concerns and basic examples in docs, and we provided standalone example for Go backend to experiment with
- Transport error mode for server HTTP and GRPC APIs #690 - read more in docs
- Support GRPC gzip compression #723. GRPC servers Centrifugo has now recognize gzip compression, proxy requests can optionally use compression for calls (see updated proxy docs).
Misc
- Release is built with Go 1.21.3
- Dependencies updated (crypto, otel, msgpack, etc)
