Amazon SNS: Notify browser client?

Question

I have long running task and I would like to update the progress to the client running a desktop browser. I want to use Amazon SNS for this. However, I've yet to find any examples or guides on how to do this.

I am using python on my backend. As the process runs, I want to post to Amazon SNS, which will then fire back to the client.

Answer 1

deepstream.io is a nodejs server for publishing AWS SNS messages directly to the browser. It's mechanism is long-polling https and wss.
