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

Introduction

JavaScript is a synchronous language and React, being a JavaScript framework, is synchronous too. Being synchronous means only one line of code can be executed at a time and the next line of code cannot start until the current code has finished executing. This can cause an issue when we make network requests. When we make network requests in a synchronous fashion the code is executed sequentially from top to bottom. This means when one network request is executed, the remaining code has to wait until that network request is completed, which can dramatically reduce the user experience. The solution for that is to make asynchronous callbacks for network requests where the operations run in parallel. The Promise API provides a simpler way to manage asynchronous operations compared to the traditional asynchronous callbacks. The Promise API can also be easily integrated with React, which helps us to create asynchronous operations easily when making network requests in React...
