Node Modules

This lesson is part of Node.js · All levels

Summary

Node.js breaks down the code into small reusable modules. A module is a JavaScript file that exports a function, object, or value via module.exports. With this pattern, projects become more organized and easier to test because each responsibility is on its own file.

Key points

Modules are JS files that export API via module.exports
Local modules are loaded with require('./path/file') and external packets with require('nama')
The node caches the module so it doesn't reload repeatedly
The node provides built-in modules such as fs, path, http, and os
