Mongoose is the most popular library for using Mongodb on Node.js.
I took some time to learn about the case sentivity and model name renaming it does behind the curtain.
Let’s assume the model I have is ‘Campaign’.
mongodb collection name is case sensitive (‘Campaigns’ is different from ‘campaigns’)
mongodb best practises is to have all lower case for collection name (‘campaigns’ is preferred)
mongoose model name should be singular and upper case (‘Campaign’)
mongoose will lowercase and pluralize with an ‘s’ so that it can access the collection (‘Campaign’ » ‘campaigns’)
Knowing this is especially useful if you are dealing with existing collections.
