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.

React Native

As the name suggests, React Native is used to build native applications in iOS and Android platforms using JavaScript and ReactJS. Some of the key features of React Native, favored by the Facebook developer teams ( for the native platforms, are mentioned here:

  • It has the power of consistency in look and feel using React component counterparts

  • You can develop the app using Chrome developer tools and run in a simulator

  • There is asynchronous execution of all the code between the application and the native platform

  • React Native seamlessly handles touch events, polyfills, StyleSheet abstraction, designing common UI layouts

  • It's widely used to extend native code creating iOS and Android modules and views and reusing them later, with ease

  • React Native's qualities of being declarative, asynchronous, and responsive are highly beneficial for iOS development
