SproutCore Web Application Development

By: Tyler Keating

Overview of this book

SproutCore is a framework that exists to allow developers to deliver on the promise of the Web with more than just simple attractive demos, but with complex software and remarkable user experiences. SproutCore’s creators recognized early on that developing real web software requires the same software development tools and practices that have evolved over decades in the native software field and thus SproutCore brings these to the Web. SproutCore Web Application Development is more than just a guide to one of the largest and most powerful web application frameworks out there, it’s also a guide to writing genre defining web applications and solving the unique problems that the web platform creates. Containing the results of thousands of hours of software development experience, this book is invaluable for anyone already writing software for the Web or just starting out. SproutCore Web Application Development comprises of three sections. In the first section we introduce SproutCore and walk through a simple SproutCore application. From there, we look in detail at all of the main components of the framework before finally working through a rigorous real-world example from start to finish. Learning about SproutCore means learning about writing software for the Web. In this book, you will not only learn what sets SproutCore apart from other web libraries and frameworks, you will also learn about solving the difficult challenges that web development poses. We will look at all the components of an application and how to translate wireframes, mocks, and design descriptions into clean, efficient, and maintainable code using MVC, data adaptors, statecharts, and more. We will look at SproutCore’s powerful binding and observing and watch how changes propagate across our app effortlessly and magically with very little code. By the time you complete SproutCore Web Application Development, you’ll be ready to develop your own application that redefines what it means to be a web application.

Chapter 4. The Model Layer

In this chapter, we will move to the opposite end of the application stack and look at the M or Model layer in SproutCore MVC. As it turns out, the implementation of the Model layer within SproutCore is one of the most impressive and unique features of the framework. This layer provides tools for modeling data, applying business logic, querying data, and synchronizing changes between the server and the client. Hence, we can say that the tools in this layer allow us to load raw data into our application from any remote source and use it in a simple and effective manner.

The first thing to recognize is that because we are creating applications for the web, our software is always in a client-server type of relationship where the actual data is stored separately from the application. Even when using a client-side data store such as IndexedDB or WebSQL, our application must asynchronously interface with the data store the same way it would as though the database were...
