Difference between MongoDB and Mongoose
I wanted to use the mongodb database, but I noticed that there are two different databases with either their own website and installation methods: mongodb and mongoose. So I came up asking myself this question: "Which one do I use?".
So in order to answer this question I ask the community if you could explain what are the differences between these two? And if possible pros and cons? Because they really look very similar to me.
I assume you already know that MongoDB is a NoSQL database system which stores data in the form of BSON documents. Your question, however is about the packages for Node.js.
In terms of Node.js, mongodb is the native driver for interacting with a mongodb instance and mongoose is an Object modeling tool for MongoDB.
Mongoose is built upon the MongoDB driver to provide programmers with a way to model their data.
EDIT: I do not want to comment on which is better, as this would make this answer opinionated. However I will list some advantages and disadvantages of using both approaches.
Using Mongoose, a user can define the schema for the documents in a particular collection. It provides a lot of convenience in the creation and management of data in MongoDB. On the downside, learning mongoose can take some time, and has some limitations in handling schemas that are quite complex.
However, if your collection schema is unpredictable, or you want a Mongo-shell like experience inside Node.js, then go ahead and use the MongoDB driver. It is the simplest to pick up. The downside here is that you will have to write larger amounts of code for validating the data, and the risk of errors is higher.
Mongo is NoSQL Database.
If you don't want to use any ORM for your data models then you can also use native driver mongo.js: https://github.com/mongodb/node-mongodb-native.
Mongoose is one of the orm's who give us functionality to access the mongo data with easily understandable queries.
Mongoose plays as a role of abstraction over your database model.
One more difference I found with respect to both is that it is fairly easy to connect to multiple databases with mongodb native driver while you have to use work arounds in mongoose which still have some drawbacks.
So if you wanna go for a multitenant application, go for mongodb native driver.
