The Node Craftsman Book

By: Manuel Kiessling

Overview of this book

The Node Craftsman Book helps JavaScript programmers with basic Node.js knowledge to now thoroughly master Node.js and JavaScript. This book dives you deeper into the craft of software development with Node.js and JavaScript, incuding object-orientation, test-driven development, database handling, web frameworks, and much more. The Node Craftsman Book shows you how to work with Node.js and how to think deeply about how you build your Node projects. You'll master how to build a complete Node.js application across six crafting milestones, and you'll learn many specific skills to achieve that mastery. These skills include how to work with the Node Package Manager in depth, how to connect your Node applications to databases, and how to write unit tests and end-to-end tests for your code. You'll experience the full Node.js development picture, and learn how to craft and control your Node.js applications - right through to fully-fledged web applications using REST, and integration with Angular applications.

Summary

In this chapter, we created a complete web-based CRUD application. It consists of a Node.js backend and an AngularJS frontend, connected through a RESTful web service API. We learned how to create a continuous delivery environment where end-to-end specs provide a tests suite that verifies the correctness of the web service API and a migrations setup ensures that database schema and code are in sync. The application can be run in the context of different configuration environments, allowing to keep test, dev, and production data separated.
