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.

Deploying on cloud provider


So far, we've deployed everything locally so that you can experiment freely without costs. But for us to make our service available to the wider internet, we need to deploy our cluster remotely, with a cloud provider.

DigitalOcean supports running Kubernetes clusters, and so we will sign in to our DigitalOcean dashboard and create a new cluster.

Creating a new remote cluster

After signing into your DigitalOcean account, click on the Kubernetes tab on your dashboard. You should be greeted with the message Get started with Kubernetes on DigitalOcean. Click on the Create a Cluster button and you will be shown a screen similar to how you configured your droplet:

Make sure you select at least three Nodes, where each node has at least 4 GB of RAM. Then, click Create Cluster. You'll be brought back to the main Kubernetes tab, where you can see that the cluster is being provisioned:

Click on the cluster and you'll be brought to the Overview section for the cluster:
