On "Closure: The Definitive Guide" by Michael Bolin

Posted by Ricardo Bánffy at Dec 12, 2010 05:20 PM |

“Closure: The Definitive Guide” by Michael Bolin does a nice job on explaining a battle-tested, very complex tool that helps maintaining very complex JavaScript codebases manageable and understandable. Appendix B itself is worth the book, as it explains many of the JavaScript quirks to newbies and made me learn I was not as good as I thought I was. The world would be a better place if all JavaScript programmers read the appendix.

Closure: The Definitive Guide

The rest of the book is what I expected - it teaches the reader how to build an application using Closure to your advantage, making your code more future-proof, browser-proof, more expressive, verifiable and testable. It covers the Closure Library, the Closure Compiler (a tool able to compile your JavaScript code into very compact JavaScript and Java that runs on your server - and, maybe, your mobile too), templates, widgets, AJAX, automated building and debugging. While we learn all that, the author also teaches us about the process of making a Google-sized web application. If you are at all familiar with JavaScript, the idea of doing a huge application is terrifying. After reading the book, while still scary, at least if feels possible to mere mortals.

If you are feeling the pressure of maintaining a big JavaScript project and is considering selling management the idea of migrating it to a JavaScript framework that encourages good practices (JavaScript makes it very easy to shoot yourself in the foot), this may be the book for you.

You can grab it directly on the O'Reilly web site. The e-book version comes without DRM and has Kindle, ePub, PDF and Android versions.
