Building Enterprise JavaScript Applications

For most startups and tech firms, the cost of maintenance is many times higher than the cost of development. Writing understandable, consistent, and maintainable code from outset is the only way to prevent this. This book provides you with the tools to code a feature-rich platform which is not only maintainable but also scalable.

---

Strengthen your applications by adopting Test-Driven Development (TDD), the OpenAPI Specification, Continuous Integration (CI), and container orchestration.

Key Features

Create production-grade JavaScript applications from scratch
Build microservices and deploy them to a Docker container for scaling applications
Test and deploy your code with confidence using Travis CI

Book DescriptionWith 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.
