Connecting to MongoDB through Mongoose

Mongoose is a popular object document mapper (ODM) for Node.js that provides a natural interface for working with MongoDB documents, collections, and databases. You can think of Mongoose as a superset of MongoDB functionality that is tailored to work inside Node.js. We will use Mongoose for all the details of connecting to MongoDB, defining our model schemas, and retrieving documents. One of the strengths Mongoose shares with Express is its very lightweight, flexible, and compossible approach to database queries.

Getting ready

To use Mongoose, we will need to install it to our Express application's package.json file:

npm install mongoose --save

Once saved to our package.json file, we can import Mongoose into our Express application in order to communicate with our running MongoDB process.

Note

For supplemental information on using Mongoose, you check out the official Mongoose documentation website while working through this section:http://mongoosejs.com/
