In MongoDB, is 'users' a default collection?

Question

So I've been learning MEAN through the book 'Mean Machine' and in one of their examples we connect to a db to store user info while creating our RESTful api. Now, every time that we save the user info it gets stored in a collection named 'users' even though no where in the code does it explicitly save to a users collection. Also, when I just create an empty db it does not have the 'users' collection. So, is there something that I'm missing here? Or is 'users' a default collection in MongoDB?

Answer 1

Collection creation in Mongo is implicit . You can simply pretend the collection exists in your code, it will be actually created as necessary. This is keeping in line with the schema-less philosophy: you do not need to declare anything in advance, neither the names of your databases or collections nor the data structure of the documents you're going to store within them.
