Building Enterprise JavaScript Applications

By: Daniel Li

Overview of this book

With the over-abundance of tools in the JavaScript ecosystem, it's easy to feel lost. Build tools, package managers, loaders, bundlers, linters, compilers, transpilers, typecheckers - how do you make sense of it all? In this book, we will build a simple API and React application from scratch. We begin by setting up our development environment using Git, yarn, Babel, and ESLint. Then, we will use Express, Elasticsearch and JSON Web Tokens (JWTs) to build a stateless API service. For the front-end, we will use React, Redux, and Webpack. A central theme in the book is maintaining code quality. As such, we will enforce a Test-Driven Development (TDD) process using Selenium, Cucumber, Mocha, Sinon, and Istanbul. As we progress through the book, the focus will shift towards automation and infrastructure. You will learn to work with Continuous Integration (CI) servers like Jenkins, deploying services inside Docker containers, and run them on Kubernetes. By following this book, you would gain the skills needed to build robust, production-ready applications.

Over to you

We have already gone over how to write E2E tests in a previous chapter, and we have demonstrated how to apply TDD for our Register and Login pages.

Now, we pass the baton to you so that you can improve on what we've done so that it conforms to the design, as well as complete the rest of the app in a TDD manner.


You don't need to focus on making things look pretty – that's not the focus here. Just make sure that all of the components are there and that the user flow is correct.

After you've done this, take a look at our implementation and use it to improve yours. Then, we'll take a look at unit tests and other types of testing that can be applied to front-end code.
