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.

Chapter 10. Deploying Our Application on a VPS

In the last few chapters, we created a robust user directory API, which is now ready to face the outside world. Thus, in this chapter, we'll learn how to expose our API to the World Wide Web (WWW). First, we will need to set up a Virtual Private Server (VPS) to host and serve our API, and associate it with a public, static IP address; we will achieve both of these goals using DigitalOcean (DO), a popular cloud provider. Then, to make it easier for our API consumers, we'll purchase a domain name from a domain registry, and configure its Domain Name System (DNS) records to resolve the domain name to the static IP.

By following this chapter, you will:

  • Learn to set up and secure a VPS
  • Learn about privileged ports
  • Keep processes alive using PM2
  • Set up NGINX as a reverse proxy to our API
  • Understand the architecture of the DNS
  • Purchase and configure a domain name
