Anyone know of a gem/plugin that lets you send alerts to currently
logged in users of a Rails app via AJAX?
For example, I want to send an alert like “The system will be going
down in 5 minutes for a quick upgrade. Please save your work now and
I’m working on an AJAX-heavy Rails app in which the user doesn’t
reload the entire page much, so just the standard rails flash messages
and warnings wouldn’t be too useful. Perhaps the client side would use
AJAX to poll the server for these global system alerts.
It’s no big task to write my own code for this, but this seems like
such a commonly needed feature that I’m wondering if there is already
a gem/plugin for it? Or is there another way that is commonly used to
send a global system message to users?
