This library has no v1 release, API may change. Before v1 release patch version updates only have backward-compatible changes and fixes, minor version updates can have backward-incompatible API changes. Master branch can have unreleased code. Only two last Go minor versions are officially supported by this library. Centrifuge library is a real-time core of Centrifugo server. It's a general-purpose real-time messaging library for Go programming language. Real-time messaging can help create interactive applications where events are delivered to online users with minimal delay. Chats apps, live comments, multiplayer games, real-time data visualizations, collaborative tools, etc. can all be built on top of Centrifuge library. The library is built on top of efficient client-server protocol schema and exposes various real-time oriented primitives for a developer.
Features
- Fast and optimized for low-latency communication with millions of client connections
- WebSocket bidirectional transport using JSON or binary Protobuf formats, both based on a strict Protobuf schema
- Code generation is used to push both JSON and Protobuf serialization performance to the limits
- Our own WebSocket emulation layer over HTTP-streaming (JSON + Protobuf) and Eventsource (JSON) without sticky sessions requirement for distributed setup, or SockJS (JSON only)
- Possibility to use unidirectional transports without using custom Centrifuge SDK library
- Effective non-blocking broadcasts towards client connections using individual queues
- Native authentication over HTTP middleware or custom token-based (ex. JWT)
