For heaven’s sake, format that mess!

{
   // formatted code
}
// wrapped in ```

thanks for the attention, but any tool or site to format the code

4

Yeah, he told you. Just do ``` before and after the code

You just need to edit your post and put three ` on the line before and after your code.

This is how I’m using it:

// collection.js
Rooms = new Mongo.Collection("rooms");
if(Meteor.isServer) {
	Rooms._ensureIndex({ location : "2dsphere" });
}

// publish.js
Meteor.publish("rooms-nearby", function (lat, lng) {
	return Rooms.find({
		location:{
			$near:{
				$geometry:{
					type: "Point",
					coordinates:[lat, lng]
				}, 
				$maxDistance:5000000
			}
		}
	}, {
		fields: {
			name: 1,
			_id: 1,
			location: 1
		}
	});
});

// subscribe.js
var location = Geolocation.latLng() || { lat: 0, lng: 0 };
Meteor.subscribe("rooms-nearby",location.lat,location.lng);

Using this package: https://atmospherejs.com/mdg/geolocation

I will just add that $near is forcing fallback to polling driver mode for this query, it is not so realtime as oplog.

What type must be set to lat and lng? Becouse i use simpleschema and need to specify that value
