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

When creating Node.js modules, it's important to follow best practices like using CommonJS or ES6 module syntax, keeping modules small and focused, and ensuring proper error handling.

Can you explain why keeping modules small is important?

Keeping modules small enhances readability, maintainability, and reusability. It allows developers to understand and test each module independently.

What about naming conventions for modules?

Use clear and descriptive names for your modules. It's common to use lowercase letters and hyphens to separate words, which improves clarity.

How should I handle dependencies in my modules?

Use a package manager like npm to manage dependencies. Always specify the version in your package.json to avoid breaking changes.

Any tips for testing my Node.js modules?

Yes! Use testing frameworks like Mocha or Jest. Write unit tests for each module to ensure they work as expected and catch bugs early.
