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.

Understanding Flux

Flux is the application architecture from Facebook that complements React. It's not a framework or a library, but rather a solution to a common problem—how to build scalable client-side applications.

With the Flux architecture, we can rethink how data flows inside of our application. Flux makes sure that all our data flows only in a single direction. This helps us to reason about how our application works, regardless of how small or large it is. With Flux, we can add new functionality without exploding our application's complexity or its mental model.

You might have noticed that both React and Flux share the same core concept—one-way data flow. This is why they naturally work well together. We know how data flows inside of a React component, but how does Flux implement the one-way data flow?

With Flux, we separate the concerns of our application into four logical entities:

  • Actions

  • Dispatchers

  • Stores

  • Views

Actions are objects that we create when we want to change our application...
