Overview of this book

The MERN stack is a collection of great tools—MongoDB, Express.js, React, and Node—that provide a strong base for a developer to build easily maintainable web applications. With each of them a JavaScript or JavaScript-based technology, having a shared programming language means it takes less time to develop web applications. This book focuses on providing key tasks that can help you get started, learn, understand, and build full-stack web applications. It walks you through the process of installing all the requirements and project setup to build client-side React web applications, managing synchronous and asynchronous data flows with Redux, and building real-time web applications with Socket.IO, RESTful APIs, and other concepts. This book gives you practical and clear hands-on experience so you can begin building a full-stack MERN web application. Quick Start Guides are focused, shorter titles that provide a faster paced introduction to a technology. They are for people who don't need all the detail at this point in their learning curve. The presentation has been streamlined to concentrate on the things you really need to know.

Writing Redux store enhancers

A Redux store enhancer is a higher-order function that takes a store creator function and returns a new enhanced store creator function. The createStore method is a store creator which has the following signature:

createStore = (reducer, preloadedState, enhancer) => Store 

While a store enhancer function has the following signature:

enhancer = (...optionalArguments) => ( 
createStore => (reducer, preloadedState, enhancer) => Store 

It may look a bit difficult to understand now, but you don't really have to worry if you don't get it at first because you will probably never need to write a store enhancer. The purpose of this recipe was simply to help you to understand their purpose in a very simple way.
