Approaches to find and read data

Mongoose offers many ways of querying data, but much like what we saw in Chapter 5, Interacting with Data – Creation, there is more than one way to execute your command.

• Using the QueryBuilder interface to build a query step by step before executing it at a specific point in your code

• Immediately with a single command

Here we have the best of both worlds. Using the QueryBuilder interface offers a greater level of flexibility and complexity, whereas the immediate execution option gives us a nice and easy way to quickly run simple queries.

There are a number of static model methods provided by Mongoose to assist in the bulk of find operations, including Model.find, Model.findOne, and Model.findById. We will look at these static model methods in more detail very soon, and we'll also see how we can create our own.

Using the QueryBuilder

Mongoose provides a simple QueryBuilder interface for when you want to build up the query over multiple steps before executing it...
