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.
