Mongoose __v property - hide?

To disable '__v' property, which is not recommended, use the versionKey schema option:

var Schema = new Schema({...}, { versionKey: false });

To hide it from all queries, which sometimes can be not what you want too, use the select schema type option:

var Schema = new Schema({ __v: { type: Number, select: false}})

You can disable the "__v" attribute in your Schema definitions by setting the versionKey option to false. For example:

var widgetSchema = new Schema({ ... attributes ... }, { versionKey: false });

I don't think you can globally disable them, but can only do it per Schema. You can read more about Schema's options here. You might also find the Schema set method helpful.
