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

Building React Components

Since presentation and data can be abstracted, breaking the UI down into components reduces clutter and gives more meaning to the components, which can now perform specialized tasks. Writing components as container and presentational components, also referred to as smart and dumb components, is a pattern that is commonly employed by developers in React.

Container components usually have a local state and are concerned with the implementation of data and how things work. They have minimum to no markup. These components deal with data, be it loading it, calling actions, or mutating them. When creating a shopping cart application with the wireframe shown in Figure 5.3, it would suffice to have container components at the root level, which will then retrieve and hold the data and just pass it down to its children. The child components, which are typically the presentation components, receive values to be displayed and show the required JSX on screen as output...
