Packt Publishing recently sent me a copy of Learning Alfresco Web Scripts by Ramesh Chauhan to review in exchange for my thoughts on the book which I’ll share with you now…
Web Scripts are an essential part of Alfresco. If you are extending or customizing the platform and you have time to learn only one thing about it, web scripts might very well be that thing. The reason is that they are key to so much else you might want to do such as integrating Alfresco with a third party system or customizing Alfresco Share, which is, at its core, comprised of web scripts.
Most technical books on Alfresco give some attention to web scripts, but this one dives into the details. After reading it, you’ll know how to do simple things with web scripts and you’ll have some idea of how to do more complex work beyond understanding the Model-View-Controller basics.
While the comprehensiveness is a good thing, I think it also presents a bit of a challenge which comes down to this: Who is this book for? If it is for beginners, it needs a lot more examples and could cut back on a lot of the technical detail. If it is for experts, point to existing sources for the basics and drill deeper on the interesting technical topics.
I did see a couple of bad practices in the book. First, in the chapter on Java-backed web scripts (Ch. 6) the author provides an example Spring configuration XML file that injects the lower-cased Alfresco beans into the web script class. This may sound like a trivial nitpick, but it’s actually a big no-no that I see repeatedly. If you have good reason for using the unsecured, internal-only, lower-cased beans, explain it. Otherwise, stick to the public, secured, upper-cased beans so that beginners don’t pick up a bad habit.
Similarly, there is a part that discusses where web script files can live in the Alfresco WAR. The author does point out that the extension directory is “preferred” but I don’t think this is worded strongly enough. Those other locations should have been left out entirely or maybe it could have said, “Place your files only in the extension directory. While these other locations may technically work, you should never use them.”
I was happy to see the chapter on the Maven SDK and the discussion of AMPs. And I think putting the Eclipse details later was a good idea, as one of the features of web scripts is that you don’t have to use Java or an IDE of any kind if you don’t want to. The book doesn’t cover Surf, Aikau, or Share customization in any detail, and I think that was also a good decision as those areas are too fluid at the moment and because the singular focus on web scripts is one of the book’s assets.
Overall, Learning Alfresco Web Scripts is a very thorough and comprehensive treatment of an important technical topic for Alfresco developers.
