In this lesson, you learned how to use Mongoose to interact with a MongoDB database. Let’s review some of the topics that we covered:
- Mongoose is a Node package that interacts with a running MongoDB database.
- MongoDB stores documents in collections and collections of documents in databases. Each document has key-value pairs as entries.
- Using a
Schema
, we can set the structure of documents dynamically, usingpaths
with schema types and validators. - Models are JavaScript classes that we compile from our
Schema
definitions. - You can use models to create, read, update, and delete documents from a database.
- You can query a database using
.find()
and.findOne()
. Mongo also provides query operators to allow for more complex queries.
Mongoose also allows for the creation of methods associated with a database:
.statics()
adds static “class” methods to the Models itself..methods()
adds an instance method to documents.
