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.

The Importance of Good Code

From IP to domain

Right now, we can access our API using an IP address. But if we want developers to use our API, we shouldn't expect them to remember a random sequence of numbers! Instead, we want to give them an easy-to-remember domain name such as

To do that, we must first purchase the domain name and then configure its Domain Name System (DNS) settings so that it will resolve to our server's IP address.

Buying a domain

While the DNS is responsible for resolving domain names to IP addresses, a domain registrar is the entity/business that registers the domain(s) for you. There are many registrars available; the one we will be using is Namecheap.

First, we must search for the domain we want on the Namecheap website. Although a registrar is an entity that can register domain names for many TLDs, it must first check with one or more domain registries to see whether the domain name is available. Domain registries collectively hold a list of all domain names and their availability...
