Mongoose select fields (nested)

Question

I am trying to use the select operator in mongoose to select certain fields for the following object:

{
    \"_id\" : ObjectId(\"5249bb97a5de48bda3000003\"),

You can use the same dot notation style in the select object with Mongoose as you do in your find example:

var fields = { 'properties.OBJECTID': 1, 'properties.TIMESTAMP': 1 };
var query = Feature.find({id: 1}).select(fields);

You can also use a Mongoose style selection string:

var query = Feature.find({id: 1})
    .select('properties.OBJECTID properties.TIMESTAMP');
