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.

The Importance of Good Code


In this chapter, we implemented the logic to allow users to authenticate themselves to our API server. We also used JSON web tokens to keep our application stateless; this is important when we want to scale your application, something which we will discuss in Chapter 18, Robust Infrastructure with Kubernetes.

However, it is important to remember that security is not an easy undertaking. What we've covered in this chapter is only a small part of the puzzle. You should view this chapter as a first step in securing your application, and always stay informed about the latest security holes and best practices.

In the next chapter, we will finish up our backend API by documenting our API using OpenAPI and Swagger.
