How get the data of the nested JSON object MongoDB with node.js

Question

I have a JSON object on MongoDB

I can`t understand how to get Products by ID from the Menu?

Answer 1

You can read that by using the following command.
To read a single data from array:

db.dbname.findOne({'products': 
     {$elemMatch:{
          '_id': id_of_the_product_you_want_to_read
           }
     }})

You can change the parameters _id to the necessary parameter you want.
