Advice for Node.js and CouchDb Application Structure

I'm trying to build a simple web application using Node.js and CouchDb.

The application will store tweets from Twitter's Streaming API into a CouchDb database and then feed these back into a web application real time.

At the moment I have created a simple Node.js script which can store the tweets into a database and I can have this run in the background, however, I'm stuck on how to feed back the results to users.

Should I have this (the feeding of tweets to end users) sit in a separate script which also run in the background? Or should I bundle this up with my current script?, if so how would this look (pseudo)?

I'm new to Node.js so some guidelin开发者_开发技巧es on the best way to do this would be great!

Thanks in advance.

Couldn't the stream backwards be fed from COuchDB's continuous or triggered _changes notifications?

Regarding CouchDB's http api, I think it is not mandatory to put node.js between this, until node.js has other tasks like filtering or is acting as a security layer?
