如何使用mongoose应用geoNear并获得两个坐标之间的距离

Question

I am looking for a solution to retrieve docs from my collection by applying a query in Node. The Purpose is to retrieve the distance between two coordinates. It can be implemented using Native MongoDb but i want to get results with mongoose. How do i do that ?

Answer 1

The geoNear method from mongoose is used as following:

Model.geoNear([1,3], { maxDistance : 5, spherical : true }, function(err, results, stats) {
   console.log(results);
});

// geoJson
var point = { type : "Point", coordinates : [9,9] };
Model.geoNear(point, { maxDistance : 5, spherical : true }, function(err, results, stats) {
   console.log(results);
});
