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 overview of Flux

Flux should not be confused as a framework based on ReactJS. Flux is an architecture and is designed in order to reduce the complexity of a huge application built with Model View Controller (MVC) architecture and has been designed as an alternative of MVC.

The following are the different Flux components:

  • View—This is like for any web app, the views (basically the react component) receives the event and passes it to the Actions

  • Action—They are helper methods (actionCreators) that pass the data (payload) and actionType, received from an external API/view to a dispatcher

  • Dispatcher—These are Central hub of all registered callbacks. It receives the actions and acts as a "traffic controller" before it passes it to the Stores

  • Store—It is a data layer that stores all the computations and business logic. It is also responsible for storing the application state and the single source of truth for the application state. It receives the action from the dispatchers based on the registered...
