Introduction:

Developers and architects who have worked with web app stacks other than the MERN stack in the past will find this book beneficial for learning about this cutting-edge stack. Discover the features of React 16 in this book to make the most of this library. To create JavaScript-based SPAs, you’ll need to use tools like Babel and Webpack. Additionally, you’ll discover how to assemble all the parts into a finished web application. Numerous additional complimentary tools are also covered in this book, including React Router, GraphQL, React-Bootstrap, Babel, and Webpack.This revised edition will make use of the most recent versions of React (16) and React Router (4), which take a very different approach to routing than React Router 2, which was used in the book’s first edition. This book should be valuable and beneficial to you, I hope.

Mern Stack:

MongoDB, Express, React, and NodeJS are collectively referred to as the MERN stack. With the help of this framework, programmers can create web apps on top of well-liked Javascript frameworks. Web application development with the MERN Stack is quite effective. The development of the MERN Stack has various advantages, including shorter development times, scalability, and cost reduction. Due to how easily complex web applications can be created using the MERN Stack development framework, with a lot of features and functionality, without losing efficiency and scalability, it has become more and more popular in recent years. Developers for the MERN Stack are in high demand since they are required to build apps that leverage the MERN Stack. They are also required when utilising these technologies to create online and mobile applications. One of the most difficult and in-demand job titles in the world is MERN Stack Developer. The demand for MERN Stack Developers is rising as MERN Stack gains in popularity. Now is the time to start your research and get ready for a successful future if you’re interested in a profession in MERN Stack Development.

Topics covered by this book:

  • Introduction is covered in Chapter 1, where we learn about web application development. Even a few years ago, web application development was not what it is now.

  • A basic MERN application, the Hello World example in Chapter 2, is given at the beginning of the chapter. Any Hello World exercise’s main goal is to establish a setting with the majority of the stack’s technological components.

  • React components are covered in Chapter 3. React components have a role in this. React components respond to user input, alter state, communicate with other components, and do many more things.

  • When the button in Chapter 4 is clicked, a row will be added to the original list of problems. This button will be added underneath the Issues table. By doing so, you will gain knowledge of a component’s state as well as how to change it, deal with events, and connect with other components.

  • Instead of using the hard-coded array of problems in the browser’s memory, Chapter 5 begins saving data to and retrieving it from the Node.js server. The goal is to become accustomed to using REST APIs to communicate with the server.

  • You may read more about MongoDB in Chapter 6. The intention is to go from using an in-memory list of issues to adding and retrieving issues from a MongoDB database.

  • You’ll take a break from routine coding and feature addition in chapter 7. Instead, you’ll structure a little bit so that your application can expand while being manageable.

  • You’ll learn about routing, or how to handle many pages that you might need to display, in chapter 8.

  • About Forms is Chapter 9. Every web application needs user input, and the Issue Tracker is no different. When you filled out a form to create a new issue, you received some user input. However, it was incredibly simplistic and did not show how React was supposed to handle forms.
