What it is

Centrifugo is a scalable, language-agnostic real-time messaging server that implements a PUB/SUB pattern over modern transports (WebSocket, HTTP-streaming, Server-Sent Events, gRPC, WebTransport). It decouples real-time communication from application backends, allowing developers to publish messages into channels via HTTP/gRPC API while clients subscribe using official SDKs. Monolithic Go application structured under internal/ with specialized packages: internal/api (HTTP/gRPC handlers with code-generation), internal/apiproto (Protocol Buffer definitions and OpenAPI/Swagger schema), internal/app (server engine, clustering, TLS, logging), internal/admin (web UI handlers), and internal/cli…

Start here

Open these first:

  • internal/app/node.go — Core node orchestration and lifecycle management for the messaging server.
  • internal/api/api.go — Central API handler multiplexing HTTP, gRPC, and WebSocket protocol requests.
  • internal/config/config.go — Configuration schema and validation for all server settings.
  • internal/client/client.go — Client connection state management and subscription handling.
  • internal/apiproto/api.proto — Protocol buffer definitions for gRPC and messaging API contracts.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and inspect: git clone https://github.com/centrifugal/centrifugo.git && cd centrifugo. Verify Go version (go.mod declares 1.26) and run go mod download. No Makefile or package.json; use go build or go run…

Daily commands:

Use go run ./cmd/centrifugo (inferred from cmd.go in internal/app) with appropriate flags like --config config.toml for configuration files (TOML via pelletier/go-toml/v2). The admin UI can be enabled with `--admin.…

…shortened for this brief.

Key cautions & unknowns

  • Single-maintainer risk — top contributor 86% of recent commits
    1. Code generation is mandatory: api.proto changes require running internal/apiproto/generate.sh or code will be out of sync. 2. Configuration is complex: multiple brokers (NATS, Kafka, SQS, Azure, GCP) are optional…
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
