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 to JSX

To be able to write components in React, we need to understand the primary templating language that React uses to build a component: JSX. The best way to describe JSX is as a type of hybrid between HTML and JavaScript.

JSX represents the easiest way to break down the boundaries between the HTML that you use as a basic markup for your web page, basically the UI of your app and the JavaScript that you need to make your app interactive. Ultimately, the JSX gets turned into JavaScript function calls behind the scenes, which enables you to write your components in a way that is comfortable and familiar for people used to working with writing HTML for a browser.

You can use most of the standard HTML tags and syntax that you already know (with a few notable exceptions), but you can also intersperse JavaScript into your templates to better approach laying things out programmatically. The idea is that if you can read HTML and JavaScript, you should be able to read...
