Getting Started with React

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.

An introduction to Webpack

Webpack is a module bundler, which is used to deploy JavaScript-based applications. It takes the input as modules with dependencies and then outputs these into static assets.

From the Webpack documentation site (, the following image explains the same.

Building a simple React application

As in the earlier chapters, let's build a simple React-based application with which we will be integrating the Webpack and deploy thereafter.

Install the packages vis npm from a terminal as:

sudo npm install babel-loader babel-preset-es2015 babel-preset-react babel-preset-stage-2
npm -g install httpster


httpster: It is a simple http server to run the static content. In chrome browser, the index.html file sometimes doesn't render due to the X-origin error. Hence, running this webserver from your application directory will be easier to test your application in Chrome. Just run the command httpster.
