This book is for web developers who want to learn to build fast, good-looking, native mobile applications using the skills they already have. If you already have some JavaScript knowledge or are using React on the web, then you will be able to quickly get up and running with React Native for iOS and Android.
What You Will LearnSet up the React Native environment on both devices and emulatorsGain an in-depth understanding of how React Native works behind the scenesWrite your own custom native UI componentsLearn the ins and outs of screen navigationMaster the art of layout and stylesWork with device-exclusive data such as geolocationDevelop native modules in Objective-C and Java that interact with JavaScriptTest and deploy your application for a production-ready environmentIn DetailReact Native is a game-changing approach to hybrid mobile development. Web developers can leverage their existing skills to write mobile applications in JavaScript that are truly native without using cross-compilation or web views. These applications have all of the advantages of those written in Objective-C or Java, combined with the rapid development cycle that JavaScript developers are accustomed to.
Web developers who want to develop native mobile applications face a high barrier to entry, because they are forced to learn platform-specific languages and frameworks. Numerous hybrid technologies have tried to simplify this process, but have failed to achieve the performance and appearance that users expect.
This book will show you all the advantages of true native development that React Native has without the steep learning curve, leveraging the knowledge you already have. We do this by getting you up and running quickly with a sample application. Next, we'll introduce you to the fundamentals of creating components and explain how React Native works under the hood. Once you have established a solid foundation, you will dive headfirst into developing a real-world application from start to finish. Along the way, we will demonstrate how to create multiple screens and navigate between them,use layout and style native UI components, and access native APIs such as local storage and geolocation. Finally, we tackle the advanced topic of Native modules, which demonstrates that there are truly no limits to what you can do with React Native.
Style and approachThis book provides a simple and easy way to build mobile applications in JavaScript. Each topic takes you through the life cycle of creating a fully-functional native app, with detailed explanations of the entire process.
Ethan Holmes is a Software Engineer from Vancouver, BC, Canada. He obtained a B.Sc. in computer science from Simon Fraser University. He has primarily been a full-stack web developer working and creating applications for start-ups in the Silicon Beach area. Currently, he is stationed at Cargomatic, disrupting the freight industry. After learning React for the web, learning React Native complemented the skills he obtained as a web developer and allowed him to quickly make the transition to mobile development.

Tom Bray has been developing for the web since the browser wars of the late 90s when DHTML was the buzzword of the day. Creating great user experiences using the cutting edge technologies of the day has always been his passion, from Flash to Flex to Adobe AIR to React, and React Native. He has created sophisticated software that has been used by large companies, such as Adobe, MySpace, Cisco, Informatica, and Dell; it has been a key contributor to numerous start-ups where he has worn many hats and gained a broad skill set. He currently serves as the Principal Software Architect with Cargomatic where he has designed a system to orchestrate the movement of ocean freight to and from America's ports—a solution that leveraged React Native to assign work to truck drivers and track their progress.
