CoffeeScript Application Development

By: Ian Greenleaf Young

Overview of this book

JavaScript is becoming one of the key languages in web development. It is now more important than ever across a growing list of platforms. CoffeeScript puts the fun back into JavaScript programming with elegant syntax and powerful features. CoffeeScript Application Development will give you an in-depth look at the CoffeeScript language, all while building a working web application. Along the way, you'll see all the great features CoffeeScript has to offer, and learn how to use them to deal with real problems like sprawling codebases, incomplete data, and asynchronous web requests. Through the course of this book you will learn the CoffeeScript syntax and see it demonstrated with simple examples. As you go, you'll put your new skills into practice by building a web application, piece by piece. You'll start with standard language features such as loops, functions, and string manipulation. Then, we'll delve into advanced features like classes and inheritance. Learn advanced idioms to deal with common occurrences like external web requests, and hone your technique for development tasks like debugging and refactoring. CoffeeScript Application Development will teach you not only how to write CoffeeScript, but also how to build solid applications that run smoothly and are a pleasure to maintain.

In this chapter, we:

  • Learned how to make asynchronous AJAX requests with a callback to process the response.

  • Integrated a third-party library for easier AJAX requests.

  • Learned how to perform multiple asynchronous operations at once, and how to track when they finished.

  • Used these skills to request information from DuckDuckGo's API and display it in our pet store application.

  • Used Promises, Async.js, and IcedCoffeeScript to help us control the flow of asynchronous code.

Asynchronous operations are a common sight in JavaScript, and we got some useful experience working with them in CoffeeScript. We learned some helpful features of CoffeeScript that help us keep our operations on track, and we learned some good architectural principles to keep in mind when working with asynchronous code of any sort.

The features we've added in this chapter mark the end of the new functionality we'll be adding to our pet shop application. It looks pretty good, don't you think? We'll still be working with the...
