Roy Derks is a serial start-up CTO, conference speaker, and developer from Amsterdam. He has been actively programming since he was a teenager, starting as a self-taught programmer using online tutorials and books. At the age of 14, he founded his first start-up, a peer-to-peer platform where users could trade DVDs with other users for free. This marked the start of his career in web development, which back then primarily consisted of creating web applications using an MVC architecture with the LAMP stack.

In 2015, he was introduced to React and GraphQL at a hackathon in Berlin, and after winning a prize for his project, he started to use these technologies professionally. Over the next few years, he helped multiple start-ups create cross-platform applications using React and React Native, including a start-up he co-founded. He also started giving workshops and talks at conferences around the globe. In 2019, he gave over 20 conference talks about React, React Native, and GraphQL, inspiring over 10,000 developers worldwide.

Kirill Ezhemenskii is an experienced software engineer, frontend and mobile developer, solution architect, and a CTO at a healthcare company. He is also a functional programming advocate and an expert in React stack, GraphQL, and TypeScript. He is a React Native mentor.

This book will help you take your React knowledge to the next level by showing how to apply both basic and advanced React patterns to create cross-platform applications. The concepts of React are described in a way that's understandable to both new and experienced developers; no prior experience of React is required, although it would help.

In each of the 12 chapters of this book, you'll create a project with React, React Native, or React 360. The projects created in these chapters implement popular React features such as Higher-Order Components ( HOCs ) for re-using logic, the context API for state-management, and Hooks for life cycle. Popular libraries, such as React Router and React Navigation, are used for routing, while the JavaScript testing framework Jest is used to write unit tests for the applications. Also, some more advanced chapters involve a GraphQL server, and Expo is used to help you create React Native applications.
