Realtime node.js app vs. mongodb

Question

I have a node.js app that polls every x seconds a mongodb database to show data variations.

I think there must be a better way to do it, using all the capabilities of node.js environment ... which is the most efficient way to trigger mongodb data variations and showing them using node?
