Mongoose for Application Development

By: Simon Holmes

Overview of this book

Mongoose is all about putting the data model where it should be: in your application. You can control everything from within your application in JavaScript, eliminating the need to work with the database or a separate management system. Mongoose for Application Development is a practical, hands-on guide that takes you from installing the technology stack through the steps of developing a web application. It covers the key features of Mongoose and how to use them to rapidly develop a Node.js and MongoDB application. This book introduces the full technology stack of Node.js, MongoDB, Express, and Mongoose. It will take you through the process of building an application on this stack with a focus on how Mongoose makes the process quicker and easier. You will see how Mongoose removes a layer of complexity when dealing with MongoDB whilst giving you more control over your data from your application. You will learn how to define schemas and models for your data in JavaScript. Using these schemas and models, you will learn how to build the cornerstone of any web application that will include CRUD operations (creating, reading, updating, and deleting data). If you want to learn how to build applications quickly and efficiently using Node.js, then Mongoose and this book are ideal for you. Using practical examples throughout, Mongoose for Application Development not only teaches you about the concepts of Mongoose, but walks through how to use them to build a real-life application.

Model methods and instance methods


As we have seen in Chapter 3, Schemas and Models, a document in a Mongoose collection is a single instance of a model. So it makes sense that if we're going to work with our data then it will be through the model.

So what do we mean by model methods? Well, if we have a model called User, some of the methods provided by Mongoose are User.create, User.find, User.update, and User.remove. The method names may be slightly different, but out of the box we've got methods for all four CRUD (Create, Read, Update, and Delete) operations right there.

Instance methods are the same concept, except that they are applied to specific instances instead. We will look at a good example of this soon, with the instance.save method.

Mongoose also allows you to define your own model methods, giving you the flexibility to create the functionality you want. We'll see more about these static methods and create one ourselves in Chapter 6, Interacting with Data – Reading, Querying, and...
