nginx-module-nchan - Scalable, flexible pub/sub server for the modern web
- Description:
Nchan is a scalable, flexible pub/sub server for the modern web,
built as a module for the NGINX web server. It can be configured
as a standalone server, or as a shim between your application
and hundreds, thousands, or millions of live subscribers.
It can buffer messages in memory, on-disk, or via Redis.
Messages are published to channels with HTTP POST requests or
Websocket, and subscribed also through Websocket, long-polling,
EventSource (SSE), old-fashioned interval polling, and more.
In a web browser, you can use Websocket or EventSource natively,
or the NchanSubscriber.js wrapper library. It supports Long-Polling,
EventSource, and resumable Websockets, and has a few other added
convenience options. It's also available on NPM.
- Architecture:
Optimized for aarch64 (ARM64) architecture. It can be used on AWS Graviton instances, as well as Raspberry Pi 4 and newer.

This package is compatible with all RHEL-based distributions, including CentOS, AlmaLinux, Oracle Linux, Rocky Linux, etc.
