Node.js modules are self-contained pieces of code that can be imported using `require`. The `module.exports` object allows exposing functions, variables, or objects from a module for use in other parts of the application. By understanding how `require` and `module.exports` work, developers can craft robust, modular code that promotes code reuse, maintainability, and scalability.
Comprehensive guide to JavaScript modules comparing CommonJS, AMD, and ES6: explains syntax and loading models (CommonJS synchronous for Node/legacy, AMD asynchronous for large apps, ES6 native modules with tree shaking for modern web), shows when to choose each, and illustrates with an ES6-based e‑commerce workflow for clean, scalable, maintainable code.
