'Opa Application Development' by Li Wenbo is a well written introductory book that can take a person with no experience of the Opa Language to feeling comfortable with the language and allowing them to start programming right away.The book is short (only about 100 pages to read through), but it is packed with examples of the topics discussed. While it doesn't cover everything about the language, it does give you enough of the basics for building your application and gives pointers where to further research on your own when you need more advanced topics.I would highly recommend this book to anyone looking to learn about the Opa language.

Opa Application Development[...]This guide/book has really explored the Opa Framework. While there are plenty to choose from after reading this I would give it a shot, I really appreciate the how to features the Author uses.You should be intermediate in your web development skills to get the most out of this book. I would recommend this to anyone looking to use this framework, it's not a cut n paste from the manual!

This is the second book I've read on Opa (the other being O'Reilly's Opa: Up and Running). I think the contents of the book have been great but the book's example code could have been better. The code itself is fine but it's organized a little strange (naming convention for example). You can download the code before hand to check it out.

This is a clear, straight-forward introduction to the Opa web-programming language. It is full of original and useful content. (Disclaimer: I was given a free copy for this review.) I am an enthusiastic admirer of the Opa language project, and found this book to be a great addition to my library. To help future buyers with their own purchasing decision, the rest of this review has been split into two parts; the bad, and the good. The bad: Not much was bad about this book, but I didn't give it all five stars, because it really is not quite as much of a book for those new to the language as it could be. I used it to help some students of mine learn about coding in Opa, and found that, really, they needed a little more background than the HTML/CSS/.js suggested as prerequisites. However, anyone with experience with Ruby on Rails, one of the Python web frameworks (Django, I'm lookin' at you ...), or any of the Javascript frameworks could easily jump right into the book and, by the end, have enough of a background to code up a pretty good, lean web app. Which brings me to. ... The good: This was a really fun way to learn Opa! (Another disclaimer: I also have read and will be reviewing another book on Opa.) I had no trouble at all using the examples in this book as a way to help me and others (my students) learn how to work the Opa web-programming language. This book is a series of guidelines, with all code explicitly spelled out. That's perfect for me, as I find the "textbook" approach, of giving problem-sets and quizzes irritating and pedantic. "Opa Application Development" is pleasantly informative and easy to understand. I am quite confident in my abilities to use Opa for production websites/web apps in the future, thanks to this book. To recap: Yes, buy this book, especially if you like (as I do) to have lots of examples presented as a guideline.

I read this book as introduction to Opa, because the language catched my eye and I was interested to learn more about it.While writing this review I have 15 years of working as developer under my belt, since the new millenium mostly with PHP.The versatility of PHP is a double-edged sword, its tempting to just stick to it, because for nearly every problem there is a solution available, but there are issues I am not happy with, so I am looking around for possible alternatives."Opa Application Development" helped me a lot in getting my head into the depths of Opa, but it is not an unconditional recommendation.Firstly you really have to have some experience in programming, because the book does expect at least basic knowledge and then some.Secondly you must expect some trouble getting Opa up and running, that the book uses more than 10% of its pages on explaining how to set everything up is indeed necessary and already the required steps are changing. For example when I installed Node.js it was in version 0.10.12 and from 0.10 and above it already includes npm, so trying to install npm separately gave me the funniest kind of errors.Thirdly there is a number of typos, also in the source code examples, but that is not so bad if you download the source examples and use the provided files.Putting this all aside, if you persevere and work completely through the book, you will have the tools and knowledge to successfully start your own project in Opa.At this moment in time there are not too many books about Opa and while this book is by no means easy to digest, its is not a bad pick to get started in Opa if you have a professional background.For me it really whet my appetite for more and I will try out if I can use Opa in one of my private projects.
