Overview of this book

ReactJS, popularly known as the V (view) of the MVC architecture, was developed by the Facebook and Instagram developers. It follows a unidirectional data flow, virtual DOM, and DOM difference that are generously leveraged in order to increase the performance of the UI. Getting Started with React will help you implement the Reactive paradigm to build stateless and asynchronous apps with React. We will begin with an overview of ReactJS and its evolution over the years, followed by building a simple React component. We will then build the same react component with JSX syntax to demystify its usage. You will see how to configure the Facebook Graph API, get your likes list, and render it using React. Following this, we will break the UI into components and you’ll learn how to establish communication between them and respond to users input/events in order to have the UI reflect their state. You’ll also get to grips with the ES6 syntaxes. Moving ahead, we will delve into the FLUX and its architecture, which is used to build client-side web applications and complements React’s composable view components by utilizing a unidirectional data flow. Towards the end, you’ll find out how to make your components reusable, and test and deploy them into a production environment. Finally, we’ll briefly touch on other topics such as React on the server side, Redux and some advanced concepts.

Chapter 7. Making Your Component Reusable

Until now, we have dug into React's components' lifecycle, properties, state, and ECMAScript with respect to React 0.1.13 and future versions. In this chapter, we will also see how we can write reusable components/code in React applications. Such reusable components in React are named Mixins. Furthermore, we will explore how the React component's properties can be validated.

The following topics to be covered in this chapter:

  • Understanding mixins

  • A higher order component in ECMA6 (as Mixin is not supported in ECMA6)

  • Different types of validations in a React application

  • The structure of a React component and application's architecture
