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 successfully built a complicated app using the useState, useEffect, and useContext/createContext hooks. We have learned about the importance of each and what sorts of problems these hooks provide solutions for. Most importantly, we have completely avoided class-based components in the entire process of implementing these complex components, each requiring states and data load/data modification for each event.

Through useEffect, we have learned how to modify the context to expose a global context to each component that needs to use it without having to resort to deep prop chaining. The data concerns for each component are now optimized, without any additional bloat in our component definitions, which is the ideal state for us. Our components are clean, lean, and very reusable.

In the next chapter, we will explore various external APIs in React in order to fetch data from the servers.
