Overview of this book

React 16 Essentials, Second Edition, fully updated for React 16, takes you on a fast-paced journey through building your own maintainable React 16 applications. React experts Artemij Fedosejev and Adam Boduch give you all the essentials you need to know and start working with React 16, in this new edition of the best-selling React.js Essentials title. You'll find the latest React 16 code updates, assessment of React Fiber, new coverage of Redux, and how to work as a modern React developer. The authors offer you their current assessment of React Fiber, and you'll soon be exploring React 16 hands on, creating your own single and multiple user interface elements with React 16. You'll then see how to create stateless and stateful components and make them reactive. You'll also learn to interact between your components and lifecycle methods, and gauge how to effectively integrate your user interface components with other JavaScript libraries. Delve deep into the core elements of the Redux architecture and learn how to manage your application and data persistence. Then go the extra mile with the Jest test framework, and run multiple tests on your applications and find solutions to scale without complexity. Today React is used by Facebook, Instagram, Khan Academy, and Imperial College London, to name a few. Many new users recognize the benefits of React and adopt it in their own projects, forming a fast-growing community. The speed at which React has evolved promises a bright future for anyone who invests in learning it today. Let Artemij and Adam bring you a brand new look at React 16 and React Fiber, and move your web development into the future.

Why Redux?

Before we get started with refactoring your application, we'll spend a couple of minutes looking at Redux at a high level. Just enough to whet your appetite. Ready?

One store to rule them all

The first major difference between traditional Flux applications and Redux is that, with Redux, you only have one store. A traditional Flux architecture might only call for one store as well, but it might have several of them. You would think that having multiple stores could actually simplify the architecture since you could separate states by different sections of the application. Indeed, this is a good tactic, but it doesn't necessarily hold up in practice. Creating more than one store can lead to confusion. Stores are moving parts in your architecture; if you have more of them, there's more potential for something to go wrong.

Redux removes this factor by allowing only one store. You might think that this would lead to a monolithic data structure that's difficult for various application...
