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

Using the useReducer Hook

Before we can start utilizing the second hook that React offers for state management, let's go through the fundamental difference as to how useState and useReducer approach state transitions (rather, how we can set a new state). With useState, we concentrate on how to transition each individual piece of state. With useReducer, we concentrate instead on the entirety of the state and setting logical rules for state manipulation.

Now, take a look at this pseudocode (this is provided as an example; don't try to run this):

const Thermostat = () => {
  const [temperature, setTemperature] = React.useState(20);
  return (
  <>
  <div>current temperature is {temperature}</div>
  <button onClick={() => do(INCREMENT)}>increase temperature</button>
  <button onClick={() => do(DECREMENT)}>decrease temperature</button>
