Section 3 – Developing our frontend UI

Chapter 14, Creating UI with React, teaches you React from first principles, discussing concepts such as virtual DOM, pure components, and JSX. At the end of the chapter, we'll also compare different module bundlers and loaders, such as Webpack, Rollup, and SystemJS.

Chapter 15, E2E Testing in React, uses the React knowledge you've gained in the previous chapter to implement a TDD workflow involving Cucumber and Selenium and using headless browsers. We will follow this process as we implement client-side routing into our application.

Chapter 16, Managing States with Redux, explains how to use Redux to keep the state of your application consistent.
