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

This chapter provided us with a more in-depth look at state management in a less ad hoc basis through useReducer. useReducer gives us a lot of helpful state management via using functionalities such as actions and payload. Our state modifications can be controlled and managed in a way that would be difficult to implement using only the useState Hooks.

We also learned the proper way to clean up after ourselves to prevent the useEffect hook from getting us into a bad scenario where we subscribe to events and listeners and then never unsubscribe from them. You can experiment with this in your activity by removing the cleanup from your useEffect hook and seeing the result on your app.

In later chapters, we are going to dive even deeper into hooks, focusing on how to deal with shared context via Hooks to build great components with shared services.
