MongoDB's geospatial features make it pretty easy to build a Meteor application
with location based services. This demo shows a
Leaflet-powered map and a text based listing of
restaurants, with reactive behavior when the map is updated (dragged, zoomed,
etc.). Using MongoDB's $geoWithin geospatial operator (which only works on the
server, not with minimongo) a restaurants subscription is created based on
the current GPS bounds of the map.
A live demo is available here.
