Overview of this book

Backbone.js is a popular library to build single page applications used by many start-ups around the world because of its flexibility, robustness and simplicity. It allows you to bring your own tools and libraries to make amazing webapps with your own rules. However, due to its flexibility it is not always easy to create scalable applications with it. By learning the best practices and project organization you will be able to create maintainable and scalable web applications with Backbone.js. With this book you will start right from organizing your Backbone.js application to learn where to put each module and how to wire them. From organizing your code in a logical and physical way, you will go on to delimit view responsibilities and work with complex layouts. Synchronizing models in a two-way binding can be difficult and with sub resources attached it can be even worse. The next chapter will explain strategies for how to deal with these models. The following chapters will help you to manage module dependencies on your projects, explore strategies to upload files to a RESTful API and store information directly in the browser for using it with Backbone.js. After testing your application, you are ready to deploy it to your production environment. The final chapter will cover different flavors of authorization. The Backbone.js library can be difficult to master, but in this book you will get the necessary skill set to create applications with it, and you will be able to use any other library you want in your stack.

Uploading the avatar image at creation time

As we have seen so far, to upload and attach a file to a resource, it must already exist. How we can create a resource with a file attached? How can we create a contact that includes an avatar image?

To do so, we will need to create the resource in two steps. In the first step, we create the resource itself, and then in a second step we can upload all files we want to that resource. Yes, it's not possible to do this in a single server connection, at least without encoding the files you want to send:

Figure 5.4 Create contact process

The preceding figure shows how the process is done. Note that the model is responsible for handling these connections while the controller orchestrates the order of the communication and error handling. As we have seen previously, the ContactEditor triggers several events that the view can use to show to the user what's happening.

The views can be left as is; we should only modify the ContactEditor controller by changing...
