Hands-On Design Patterns with React Native

By: Mateusz Grzesiukiewicz

Overview of this book

React Native helps developers reuse code across different mobile platforms like iOS and Android. This book will show you effective design patterns in the React Native world and will make you ready for professional development in big teams. The book will focus only on the patterns that are relevant to JavaScript, ECMAScript, React and React Native. However, you can successfully transfer a lot of the skills and techniques to other languages. I call them “Idea patterns”. This book will start with the most standard development patterns in React like component building patterns, styling patterns in React Native and then extend these patterns to your mobile application using real world practical examples. Each chapter comes with full, separate source code of applications that you can build and run on your phone. The book is also diving into architectural patterns. Especially how to adapt MVC to React environment. You will learn Flux architecture and how Redux is implementing it. Each approach will be presented with its pros and cons. You will learn how to work with external data sources using libraries like Redux thunk and Redux Saga. The end goal is the ability to recognize the best solution for a given problem for your next mobile application.

JavaScript and functional programming

Functional programming basically means using functions in a certain way to write a logical piece of code. Most languages allow functions to be really complex and hard to understand. Functional programming, however, puts constraints on functions in order to be able to compose them and mathematically prove something about their behaviour.

One of the constraints is the regulation of communication with the external world (for instance, side effects, such as data fetching). Some assert that no matter how many times we call a function with the same arguments, it will return the exact same value. All of these constraints will give us certain benefits. You can name some of these benefits already, such as time-traveling, which uses pure reducers.

In this chapter, we will learn a bunch of useful functions that will ease us into Chapter 9, Elements of...
