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.

Server-side rendering

Server-side rendering in ReactJS is done by JavaScript (NodeJS or io.js). This method actually prerenders the initial state of the React components at the server side. Thus, it is helpful in fast rendering of web pages, as the users can see the web pages without having to wait for the entire JavaScript at the client side to finish loading.

However, this kind of rendering should not be used for those applications where a huge amount of data has to be piped from the server to the client side, which may slow the page load. In such cases, we may use pagination or bulk load the data in chunks, which won't slow the page load, but can be fetched from the server side in specific time intervals.

The following two methods from the React API provides the backbone of server-side rendering (


The react-dom/server package allows you to render your components on the server.
