mongodb, sorting by geoNear and date?

Question

how to sort by proximity and date in mongoDB? I tried this. But they just sort by date:

   coll.find({\'date\':{$gte:date},\'location\':{$nearSphere:[lat,lng]}})

It's recommended to use $geoNear in an aggregate : https://docs.mongodb.com/manual/reference/operator/aggregation/geoNear/

You can sort on your date and distance in the aggregate :

    coll.aggregate([
   {
     $geoNear: {
        near: { type: "Point", coordinates: [ lat, lng ] },
        key: "location",
        spherical: true,
        distanceField: "dist.calculated",
        query: { "date": {"$gte": date} }
     }
   },
   {$sort: {"dist.calculated":1, "date": 1}}
])
