Mercure
Protocol for pushing data updates to web browsers and other HTTP clients over server-sent events, with a reference hub server written in Go.
Mercure is a protocol for pushing updates from a server to browsers and other HTTP clients, and its reference hub is a server that implements it. The hub is a custom build of the Caddy web server with the Mercure module. The project publishes a Docker image, a Compose file, a Helm chart and prebuilt archives, and a Go library is available for applications written in Go.
Worth knowing
The license page states AGPL-3.0 for the hub and offers a commercial license through Mercure Enterprise. The paid tiers add multi-node clustering and the Redis and PostgreSQL transports, and the hosted Mercure Cloud runs its servers in Amsterdam.
