Module Patterns

Understanding and using the Node module system

About the Book

The first short book of this series is a short introduction that sets the foundation of the next books to come. It shows what you can do with JavaScript and the Node module system to create and consume different types of modules: Singletons, Closure-based and prototype-based pseudo-classes, façades and others.
