MongooseJS Find Max, Min and Avg Number

I have a MongoDB database containing a series of values including a Number field, I wish to get the maximum number, minimum and average. How is the best way to do this using mongoosejs and nodejs?

node.js
mongodb
mongoose
locomotivejs

I recomend you to use "agregation".

Here you can find some examples: SQL to Agregation

I hope it helps. Regards,
