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

In the previous chapter, we have introduced React Router and saw some practical examples of how to construct simple routes. We now understand what routing is and why React Router v4 is a solid choice when it comes to defining routes, and how to use links, exact matches, and transitions.

There are situations, however, that might require you to implement additional functionalities. For example, when we navigate to a page using deep links, links that can be used navigate to a specific indexed page in our application, we may need to pass a few parameters, such as tokens or IDs. In this chapter, we will learn how to handle URL parameters and how to retrieve them via route props. We will also learn how to restrict access to routes, either by preventing navigating out of the current view to prevent losing existing form data or handling and storing navigation into the view layer if the user has no permissions or is not authenticated. This is possible with the use of Higher...
