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.

Introduction

While building React applications, to improve their quality, we should use industry best practices. Data and its flow are important in our applications and for guidance, it is important to consider the Model-View-Controller (MVC) architecture. MVC is a common architectural pattern that is comprised of three main logical components: the Model, the View, and the Controller. The Model relates to data in the application and might even connect to a database. The Controller holds any business logic and causes changes to be made to the Model. Finally, the View is the presentation layer where changes in the Model are reciprocated.

In information technology, another aspect to consider is that software systems can store information about user interactions and events in something called the state. It is used to serve relevant content. A system that uses state is said to be stateful.

The Model part of the MVC architecture and the state in a stateful system are key to data integrity...
