Pro MERN Stack: Full Stack Web App Development with Mongo, Express, React, and Node - Softcover

Chapter 1: Why MERN

This is an introductory chapter that discusses the history of React and MERN and why it's suitable for a variety of web apps. One interesting topic that I will be discussing here is why it was created and what problem it tried to solve. This will give great insights into what kind of apps React is most suitable for, and for what kind of apps it will be a misfit.

Chapter 2: Intro to React and Hello World

This chapter starts with installation of some basic components: Node, npm, Express, Babel and React. Then, the first pieces of code is written, which brings up the customary Hello World app. All the code at this point is in React (ie, no server side coding). I introduce the basics of React in this chapter.

Chapter 3: React Components

Here, I'll invent the functional requirements of our sample app that we'll use throughout the book. Then, I'll start off the first important concept of React: components and composition. Using this, we'll build the first cut of the sample app - we'll build the UI to show a list of bugs, a placeholder for a filter to control the list and another placeholder which will become a form to add a bug to the list.

Chapter 4: Data from Server

In this chapter, I will describe how data can be served from the server via APIs. I'll introduce Express and describe how to create REST APIs using Express routes. At the end of this chapter, we'll be serving the data from the server instead of hardcoded data on in our app scripts, and using this data to render our components.

Chapter 5: Using MongoDB to save the data

Here, we'll take data handling to the next level and introduce MongoDB. We'll explore how to save and retrieve data from a MongoDB database via the Mongo shell, and later, via the MongoDB Driver from our app server.

Chapter 6: Build and Bundle using Webpack

When we have many components, it is good to modularize the app. It also becomes essential when we start using third party libraries. In this chapter, I show how the app can be split into modules. To manage the dependencies and create a single bundle containing all the front-end code, we will use a utility called webpack. At the end of this chapter, we have a complete stack and the required development tools all in place. Further chapters will improve our sample app by adding more features, which require other libraries and/or features of each component of the MERN stack.

Chapter 7: Dynamic Components and Interactivity

We'll take Components to the next level in this chapter. I'll cover how to dynamically update components by manipulating state, how to deal with user interaction and finally how to communicate between components. At the end of this chapter, the user will be able to add a record to the list using a form.

Chapter 8: Routing using React Router

Routing is the act of switching between sections of the app using a URL that indicates where we are. In a single page app (SPA) a new URL does not translate to a full page request to the server, the DOM is updated by making lightweight ajax calls. React by itself does not mandate any particular routing mechanism, but fortunately there are other libraries that simplify routing for us. In this chapter, we'll introduce React Router and use that to route between different views in the app.

Chapter 9: Forms and Component Lifecycle

Handling user input via forms the React is a little different from the conventional Javascript / jQuery way. In this chapter we'll explore how user input is captured. We'll explore controlled components and uncontrolled components and which is one is appropriate in which situation. We'll now have proper forms acting as input to adding a new bug, editing an existing one, and setting a new filter.

Chapter 10: Using React Bootstrap

React Bootstrap is an epitome of how to build reusable React components. By using s
