Mastering Backbone.js

By: Abiee Echamea

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.

IndexedDB, on the other hand, does not have this limitation; however, it has a complex API. The main downside of IndexedDB is that it is not fully supported on all major browsers:

Figure 6.4: Browser support for IndexedDB

At the moment of writing this book, IndexedDB is fully supported by Chrome and Firefox, while Safari and IE have partial support.

A big difference between localStorage and IndexedDB is that IndexedDB is not a key/value store; IndexedDB has collections (tables) and a query API. If you have worked with MongoDB, you will be familiar with the way IndexedDB stores data.

Getting started with IndexedDB

An IndexedDB database is composed of one or more stores. A store is like a JSON container, it contains a collection of JSON. If you have worked with SQL, then a store is like a table. If you have worked with MongoDB, a store is a like a collection...
