The animal on the cover of Building Web Apps with WordPress is a common iguana (Iguana iguana). This reptile is native to Central and South America, and its range encompasses parts of Mexico and extends all the way down to southern Brazil. There are also populations in South Florida, Hawaii, and the Rio Grande Valley in Texas that arose from the escape or disposal of captive individuals. In some South American countries, iguana eggs are sold as a novelty food; they are boiled in salt and can fetch twice the price of a chicken egg.
The word iguana is derived from the language of the Taíno people, who called the lizard iwana. Despite being commonly known as the green iguana, this species can be many different colors, depending on their area of origin. In the more southern countries of their range, iguanas appear more bluish in color, with bright blue markings. On islands like Aruba and Grenada, their skin can be lavender or black; individuals from the western side of Costa Rica are red, and Mexican iguanas tend to be a light orange.
Iguanas are excellent climbers and can fall for about 50 feet without being hurt. Their strong back legs and claws allow them to grasp branches and make long leaps from tree to tree. As well as being at home in the canopy, iguanas are natural swimmers who use their powerful tails to propel them through the water. Their tails are also used as weapons to protect the iguanas from predators or to incapacitate a rival. If the tail gets caught in something, the iguana will allow it to break in order to escape; a new tail eventually grows out to replace the old one.
Because of their dramatic looks and laid-back nature, green iguanas are popular pets. However, they require specialized care, and it is sadly very common for iguanas to be abandoned or disposed of because an owner could not provide the correct environment. They need to be provided with varied leafy vegetables and access to fresh water, and should be kept at a constant temperature of 79°F and given access to UVA and UVB lighting. An iguana can live up to 20 years if cared for properly, so the decision to keep one as a pet should be given much consideration.
Comments about oreilly Building Web Apps with WordPress:
I was looking forward to a guide to creating a full-featured web app using WordPress but this book didn't really do that.
"you'll learn how to use WordPress plugins and themes to develop fast, scalable, and secure web apps" I don't don't agree with that description.
It basically goes through a lot of functionality that you can hook into to change how wordpress behaves, but nothing like a full example of anything. For that you just need to go through the source code.
It was hard to follow the examples because there are no named files in the examples to reference to their SchoolPress application, just some sample code snippets that aren't always fully-working examples. I'm happy to dig into source code but give me some idea where the code should be or where I can see a good example of how this works.
I didn't think the book was terrible, just not what I would have expected given the title. The writing is clear overall.
I would suggest a more classic book on developing wordpress plugins to better cover the code behind the topics that I was hoping would be in this book.
Bottom Line No, I would not recommend this to a friend

Comments about oreilly Building Web Apps with WordPress:
XML-RPC is not very used today, now exist the JSON API and this part is missing in the book. The Heartbeat API is not explained, the wordpress security development pattern is not explained enough, is explained only some techniques for a better security in a wordpress environment. Woocommerce is not explained :-(
For the rest explain the basic of a wordpress system, explain buddypress, and other things really interesting.
Bottom Line Yes, I would recommend this to a friend
