A basic proximity search API built using MongoDB, node.js and express. This currently uses the Twitter Streaming API as the data source.
Built mostly as a chance to experiment with MongoDB. Twitter provides its own proximity search so this was mostly an exercise.
There are two main scripts:
ingest.js- Connects to the Twitter Streaming API and saves geo-tagged tweets into MongoDB
api.js- The public API server
/proximity?latitude=XX&longitude=XX
This provides the 100 posts nearest to the given coordinate ordered by increasing distance.
/proximity?latitude=XX&longitude=XX&q=SEARCHTERM
This filters on the given search term first then orders the posts by proximity to the given coordinate.
Both of these can take a &callback=XXX parameter to enable jsonp
