Overview of this book

Are you interested in how React takes command of the view layer for web and mobile apps and changes the data of large web applications without needing to reload the page? This workshop will help you learn how and show you how to develop and enhance web apps using the features of the React framework with interesting examples and exercises. The workshop starts by demonstrating how to create your first React project. You’ll tap into React’s popular feature JSX to develop templates and use DOM events to make your project interactive. Next, you’ll focus on the lifecycle of the React component and understand how components are created, mounted, unmounted, and destroyed. Later, you’ll create and customize components to understand the data flow in React and how props and state communicate between components. You’ll also use Formik to create forms in React to explore the concept of controlled and uncontrolled components and even play with React Router to navigate between React components. The chapters that follow will help you build an interesting image-search app to fetch data from the outside world and populate the data to the React app. Finally, you’ll understand what ref API is and how it is used to manipulate DOM in an imperative way. By the end of this React book, you’ll have the skills you need to set up and create web apps using React.

Preface

Summary

In this chapter, we have described and implemented various React component lifecycle methods. Knowing how the lifecycle perpetuates itself is critical to architecting React components that are anything larger and more complex than a couple of static boilerplate components. Moreover, it is worth understanding how the lifecycle flows adding additional functionality of events as appropriate. For example, knowing about the lifecycle allows us to determine the best place to add in functionality such as making external AJAX calls that should modify the state without doing something that would affect the rendering pipeline for the component. This is something that is borderline required for mastery of writing smart React components.

If you remember the basic flow of implementing lifecycle methods, as mentioned in the chapter, you will have enough information to get you through most of the React components that you write in your lifetime. In the next chapter, we will look at class...
