HTML5 Server-Side Events with Passenger 3.x, Rails 3.2, Ruby 1.9.3

[Dan]

Hello,

I was wondering if it's possible to implement HTML5 server-side events (SSE) with a Rails 3.2 app deployed to Passenger 3.x.  I saw there is CRAMP gem (http://cramp.in/) that looks like it supports SSE, but not sure about the Rails/Passenger compatibility and how to set it up.  I appreciate any help that can be provided.

Thanks.

Dan

FYI - I'm using Passenger with Apache...

Whether Server Side Events are properly supported depends on the web
server. So far we've not tested it. We know that Phusion Passenger 4.0
+ Nginx 1.4.0 works with WebSockets though.

What are you using for Websockets - Rails 4?  Trying to find something that works for Rails 3.2...

Hi Dan,

You can use something like websocket-rails (https://github.com/DanKnox/websocket-rails) to work with websockets, Rails itself does not come with an websocket API.

Kind regards,

Tinco

Thanks for the response! Unfortunately it sounds like that wouldn't work through Passenger with Apache. I would have to switch to standalone mode...

I did read some articles about embedding Sinatra within rails, and using that for Server-Side events.

Maybe I'll try that out, see if it's compatible with Passenger/Apache.
