What are the best practices for organizing Node.js modules?

When organizing Node.js modules, consider using a clear directory structure, keeping modules small and focused, and using meaningful names.

Can you give me an example of a good directory structure?

Sure! A common structure is:

project/
│
├── src/
│   ├── controllers/
│   ├── models/
│   ├── routes/
│   └── services/
│
├── tests/
│   └── unit/
│
└── package.json

This separates concerns and makes it easier to manage your code.

How do I handle dependencies in my modules?

Use npm or yarn to manage dependencies. Keep them listed in your package.json and use semantic versioning to avoid conflicts.

What about testing my modules?

Testing is crucial! Use frameworks like Mocha or Jest to write unit tests for your modules, ensuring they work as expected.
