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 4. Setting Up Development Tools

The first section of this book (Chapters 1-3) was written to provide sufficient background knowledge so that we can code without interruption. In this chapter, we will actually start building our user directory application, called 'hobnob', by setting up our local development environment.

The aim of this chapter is to help you understand how different tools and standards in the Node.js ecosystem work together. Specifically, we'll cover the following:

  • What is Node.js?
  • Different formats/standards for JavaScript modules
  • Managing modules with npm and yarn
  • Transpiling code with Babel
  • Watching for changes with nodemon
  • Linting our code with ESLint
