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. To enable this module after installation, add the following to /etc/nginx/nginx.conf and reload NGINX: load_module modules/ngx_nchan_module.so; Alternatively, enable all installed modules by adding this line to the top of /etc/nginx/nginx.conf: include /usr/share/nginx/modules/*.conf;

Compatible with all RHEL-based distributions, including CentOS, AlmaLinux, Oracle Linux, Rocky Linux, etc.
