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.

Understanding the View layer


The View layer in SproutCore is a powerful and thick layer. In fact, I'm going to start by asserting that the View layer will likely be the most complex layer in your application.

The reason for this being that the View layer has the difficult task of presenting the abstract computational logic and data in a manner both meaningful and easy-to-use for the human being on the other side of the screen. On top of this, it has to work with multiple rendering engines and display sizes and still be fast, smooth, and beautiful.

So, we might as well get comfortable with the idea right now. Designing and developing a User Interface (UI) is hard work. It requires the web developer to move back and forth between the programmatic language of JavaScript and the semantic languages of HTML and Cascading Style Sheets (CSS). It requires foresight and nuance and a healthy dose of iteration.

Fortunately for us, SproutCore has done all of the difficult tasks already and so we don't...
