How to make a trigger (trigger) in mongodb?

What I want is to make a record of all the movements made in the database, for this I plan to use a table blog which has the following structure:

bitacora = {
  _id,
  action: String,
  userId: String,
  create_at:{
    type: Date,
    default: Date.now
  } 
}

The idea is that every time I delete, register or modify a record that is recorded in this table. Investigating in several pages I have found some things like mongoose-trigger but I do not understand very well how to implement it. I am something new in the subject and any contribution would be great, beforehand THANK YOU!
