Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

REST is a powerful paradigm in web programming that uses the HTTP methods GET, POST, PUT, and DELETE to manage the create, read, update, and delete (often abbreviated as CRUD) actions for document management in web services.

Using REST, the URLs are nouns representing what you want to manipulate, and the HTTP methods are verbs that perform the actions on those nouns.

In the recipes that follow, we'll use node's express module to build a RESTful server that returns documents from Mongo, as well as supports the basic CRUD operations. Before you begin, you need to install three more modules.

How to do it…

You'll use npm, the Node.js package manager, to install the cross-object resource module to support cross-domain scripting, express module, and the body-parser module used by express. To do this, run in your project directory...
