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.

Advantages of Webpack

Along the various advantages of using Webpack, as yet another bundler, these are the most important ones:

  1. Code splitting: Based on the code size, it helps modularize the code chunks of code and loads these modules as and when needed. You can define the split points on your code, based on which the code chunks will be used. Thus, it helps in faster page load and performance improvement.

  2. Loaders: As in the earlier-mentioned image, in the left-hand side, you can see that there are various other formats such as coffescripts/jsx instead of JavaScript and .less instead of .css. Thus, these loaders (npm packages) are used to convert these other formats into the accepted standardized formats, which makes the life of the developers much easy to code into any format they want. In React-based applications that we were seeing earlier, JSX formats are widely used. Hence, these loaders will come handy.

  3. Clever parsing: It helps to parse most of the third-party library and handles the...
