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.

Picking a cluster management tool


Having to manage these different cluster management components individually is tedious and error-prone. Luckily, cluster management tools exist that provides a common API that allows us to configure these tools in a consistent and automated manner. You'd use the Cluster management tool's API instead of manipulating each component individually.

Cluster management tools are also known as cluster orchestration tools or container orchestration tools. Although there may be slight nuances between the different terms, we can regard them as the same for the purpose of this chapter.

There are a few popular cluster management tools available today:

  • Marathon (https://mesosphere.github.io/marathon/): By Mesosphere and runs on Apache Mesos.
  • Swarm (https://docs.docker.com/engine/swarm/): The Docker engine includesswarm mode that manages Docker containers in clusters called swarms. You may also group certain containers together using Docker Compose.
  • Kubernetes: The de facto...
