Setting Up MongoDB Using Mongoose

We need to be able to persist our todos for our application somewhere, and so we are going to use MongoDB.⁶ MongoDB, also known simply as Mongo, is a popular NoSQL document object store. It’s similar to a relational database in that you can store and retrieve data, but it’s more fluid in that it doesn’t require a traditional schema, meaning we can just start using it without writing a bunch of table creation scripts. That makes it a great choice for us because it means we don’t have to jump through a lot of hoops just building tables and the like. We can simply start throwing todos into the store.

I’m going to make the assumption here that you have MongoDB installed. If you don’t, feel free to go⁷ to do that now and come back when you’re done.
