Book Description
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.
What you will learn
- Use JSX to include logic in the view layer of applications
- Get familiar with the important methods and events in the React lifecycle
- Distinguish between class and functional component syntaxes
- Create forms with Formik and handle errors
- Understand the React Hooks API and the problems it can solve
- Fetch outside data using the Axios library and populate the data to the app
Who this book is for
The React Workshop is for web developers and programmers who are looking to learn React and use it for creating and enhancing web applications.

1. Getting Started with React
Introduction
Problems before React
- Data needs to be entered into the username field.
- Data needs to be entered into the password field.
- The user needs to click the login button.
- The user is now logged in.
- If the user's username and password do not work, the user should see a failed login message.
- If the user fails to enter a username, the user should see a message reminding them to fill in the username field.
- If the user fails to enter a password, the user should see a message reminding them to fill in the password field.
- A message box displaying information if a username/password combination is incorrect, which evidently requires interaction with the server
- A message box displaying information if either of the username/password fields is left blank
- What if we want to progressively check the username field to make sure it matches an email format if we are using emails for usernames?
- What if we want to validate whether each field has been filled (either for format or if the values have been filled) as we move through each of the fields, displaying a red box around input fields that are blank or skipped as we move along?
- Their visual state (how the field is displayed to the user)
- Their data state (what is entered into the field)
- Their state in relation to other UI elements (how the login form knows about the data state of the username and password fields)
- Their interaction state (can the button be clicked if either the username or password fields are blank?)
Introducing React
- The component
- The state
- The display (or render)
