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

React Router Special Cases

Let's look at a few special cases where we'll be using advanced routing techniques.

Passing URL Parameters between Routes

URL parameters are variables that we define in the routes and which can take a special form. We will use those parameters to handle cases where we need to pass information into the route via the URL and to create SEO-friendly links such as the following:

/recipes/stews/meat

Another example of this is as follows:

/users/theo/profile

To define URL variables, we need to prepend them with a colon (:), followed by the name of the parameter. For example, the following strings are examples of valid parameters:

:id, :username, :email, :type, :search

However, the following strings are not valid parameters:

?id, -username, &email, type, *search*

When we use parameters like this, we just need a valid link to match that route. We can access the matched parameter by name using the useParams() function...
