When we think about Design Patterns, without a mistake, we point to some code structure, that more or less defines some good practice in software development. One rule is — it must contain some code example.

Many would not consider the Module pattern as an actual pattern, not in a conventional way. It is understandable, as someone may think more about a Module as a project structure than a pattern.

Additional troubles come when we consider NodeJS Modules. They are coupled collections of code written in JavaScript and TypeScript, versioned, and released together.

The trouble is how to connect that story now with the Module pattern in the Domain-Driven Design. Is there a sense at all to do such a thing or we can live without this pattern?

As with any other pattern from Domain-Driven Design, even Module has its examples in day-to-day use in software development. Naturally, that use may differ from other languages, but the main idea is still there.

Let us examine that idea.
