MERN Quick Start Guide

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.

Composing components

In React, all components can be isolated and complex UIs can be built by composing components which enables their re-usability.

Getting ready

In this recipe, you will work with re-usable components to generate a home page containing three sections: a header, a paragraph with a description, and a footer. These three sections will be written as three separate components that will be composed later to build a home page. Before you start, create a new package.json file with the following content:

  "scripts": { 
    "start": "parcel serve -p 1337 index.html" 
  "devDependencies": { 
    "babel-plugin-transform-class-properties": "6.24.1"...
