Question

I want to use something like EventMachine websockets to push status updates to the client as they happen.

My application crawls round a section of a website screen scraping relevant details of a user’s search. I want to push any screen scraping captures to the client as they happen. I also want to persist these changes to the database. I also want the job to complete even if the user closes down the browser.

At the moment, the job is initiated from the client (browser) and the job is placed on a resque queue that completes the job. The client polls the database and displays the results.

I want to have a play around with websockets but I don’t think I can get the same behaviour. It is more important that the results are persisted and the job completes than the real time pushes.

Am I wrong in the assumption that this cannot be done?

Have you looked at faye. Masseging With Faye(RailsCasts). You can keep on using the rescue queue to get the job completed and push the message to subscriber(your web client) as and when you find the results.
