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.

Introduction to Gulp

Now that we have seen a module bundler, let's see what Gulp will do for us. Gulp is a build tool for compiling and compressing JS/assets, and it does live reload on the browsers. Gulp file is basically a file with the set of instructions, which Gulp should do. The file can have a default task or several other tasks to be called from one another.

Installing Gulp and creating Gulp file

Let's install gulp and configure it with our existing application:

npm install -g gulp (for globally installing gulp)
npm install gulp –save-dev (as a developer dependancy)

Next, create a simple gulpfile.js file at the root of your app directory:

var gulp = require('gulp');

gulp.task('default', function() {
  // tasks goes here

Let's execute the command from terminal:

Then, we are installing some other packages for Gulp-related tasks. We are adding these in our package.json file and running npm install, in order to install these:
