Overview of this book

A key technology for building web applications and tooling, Node.js brings JavaScript to the server enabling full-stack development in a common language. This fourth edition of the Node Cookbook is updated with the latest Node.js features and the evolution of the Node.js framework ecosystems. This practical guide will help you to get started with creating, debugging, and deploying your Node.js applications and cover solutions to common problems, along with tips to avoid pitfalls. You'll become familiar with the Node.js development model by learning how to handle files and build simple web applications and then explore established and emerging Node.js web frameworks such as Express.js and Fastify. As you advance, you'll discover techniques for detecting problems in your applications, handling security concerns, and deploying your applications to the cloud. This recipe-based guide will help you to easily navigate through various core topics of server-side web application development with Node.js. By the end of this Node book, you'll be well-versed with core Node.js concepts and have gained the knowledge to start building performant and scalable Node.js applications.

Deploying to Kubernetes

Kubernetes is an open source container orchestration and management system originally developed by Google. Today, the Kubernetes project is maintained by the Cloud Native Computing Foundation (https://www.cncf.io/).

Kubernetes is a comprehensive and complex tool that provides the following features, among others:

  • Service discovery and load balancing
  • Storage orchestration
  • Automated rollouts and rollbacks
  • Automatic bin packing, specifying how much CPU and memory each container needs
  • Self-healing
  • Secret and configuration management

An oversimplified description of Kubernetes is that it is a tool used to manage containers.

This recipe will serve as an introduction to Kubernetes, demonstrating how we can deploy a microservice, packaged into a Docker container, to Kubernetes.

Getting ready

You should have Node.js 14 installed, and access to both an editor and browser of your choice. This recipe also relies on the fastify...
