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.

CRUD operations with Mongoose

One of many reasons why developers opt to use Mongoose instead of the official MongoDB driver for Node.js is that it allows you to create data structures with ease by using schemas and also because of the built-in validation. MongoDB is a document-oriented database, meaning that the structure of the documents varies.

In the MVC architectural pattern, Mongoose is often used for creating models that shape or define data structures.

This is how a typical Mongoose schema would be defined and then compiled into a model:

      const PersonSchema = new Schema({ 
          firstName: String, 
          lastName: String, 
      const Person = connection.model('Person', PersonSchema) 
Model names should be in singular since Mongoose will make them plural and lowercase them when saving the collection to the database. For instance, if the...
