Learning React Native: Building Native Mobile Apps with JavaScript

This book introduces the reader to React Native which is used to build phone applications on iOS and Android. The book assumes you are familiar with the React framework from web programming already and generally familiar with JavaScript programming already. There is a slightly heavier emphasis on the iOS development than on the Android side, but both get sufficient coverage.The beginning of the book explains the purpose of React Native and how it is different from React for the web. One of the main distinctions is that you can develop for iOS and Android simultaneously, and the author does a nice job of pointing out where you may need a specific component for one framework.Towards the middle of the book there is information about how to style your app, how to handle touch screen events, and reading from different APIs. There was a lot of screen shots to help guide the reader and the examples were relevant. Deployment of the application is discussed in the later chapters.I found many places where the author said that some technique is likely to be outdated soon as the React project changes really quickly. The author gives link suggestions where to find updates and I found this to be helpful.For some reason the book is listed as 272 pages on Amazon although my print copy has the index starting at page 245. There are tons of screen shots in the book, while helpful, make the book much shorter than I was expecting. I felt some sections were skimmed over a bit too quick like Reflux/Flux which had only 4 pages for them. Overall though, the author had clear explanations and provides a nice introduction to React Native.

Totally dated information for running react native on the mac. And almost no coverage for other platforms (e.g., Ubuntu).

Pretty good introduction, but needless to say React Native's pace is faster than the book keeps up with. I would stick with online information that is current. Stack Overflow has answered more questions for me than this book has.

I anxiously anticipated the release of this book and I can now say it was worth the wait! Bonnie's writing is clear and concise. She has a way of anticipating your questions with answers seemingly to be found on the next page. With this book Bonnie demonstrates a mastery of this new technology and a facility to teach. I was up and running with my first app in a few days. This book is your React Native primer.

This is an excellent book to learn about the inner workings of React-Native, and how to apply it to your own applications.Yes, it was published in Dec 2015, so it's not up-to-date, but we're talking about a framework that releases a new major update every two weeks; that's to be expected. Regardless you can learn what you need to understand and use React-Native, but if you don't understand React.js you will not learn as much as someone that does, as well as being able to focus on native-specific differences.There is a github repo for the projects, so you can use those npm package lists that use the older react-native so that everything works as shown in the book. You can also start learning how to read react-native docs, and make your own updates so that the projects work with the latest versions; something you will need to learn how to do with this technology at some point in time anyways.There are also maybe kind users posting errata with solutions on how to update the code to the latest react-native (0.28 at the time of this review), so you can quickly update the code if you get stuck updating it yourself; that is if you are using the latest libraries. I believe the author leaves the errata as "unconfirmed" so that users can see this errata, and is probably spending her time on a whole new book, instead of updating the current, as there have been so many changes and additions since react 0.11.4 (version used in book).No matter what, this book gets you started in the world of React Native, exposes you to many resources, and teaches you the most important key points so to gain the knowledge needed to understand the framework, and easily apply it to your own react-native apps.

The content is great, but almost every single code sample is outdated and several of the examples don't even compile. Also, most of the links to React Native's docs are broken. I really wouldn't recommend this book to someone who's an absolute beginner with React Native.

Extremely well written. This should be featured on Facebook's React Native homepage (yeah, it's that good!).

As with all the other O'Reilly books I have, this one does not disappoint. It has a very linear progression through the topic with ample examples and good, thorough descriptions.

Perfect!

I love mayer, but probably buying the full css guide was a smarter choice
