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

Throughout this chapter, we practiced how to use async/await when fetching data from a server. We also covered how to catch errors by using the try/catch pattern followed by how to use async/await inside loops. Firstly, we learned what a promise is and how to use it with three methods, then(), finally(), and catch(). Also, we discovered how to use Axios to use these three methods. After that, in the exercise, we practiced how to fetch data from OpenWeather API using Axios with then(), finally(), and catch(). After that, we dived into async/await by discussing what the async and await keywords are for. And then we talked about how to use then(), error(), and finally() methods with async/await, followed by an example of a benefit of using async/await over Promise while handling errors. In addition, we discussed how to use async/await within loops and saw an example of when to use for…of and map(), and also why the forEach() method is not recommended.
