What Are Node Packaged Modules?

A Node Packaged Module is a packaged library that can easily be shared, reused, and installed in different projects. There are many different modules available for a variety of purposes. For example, the Mongoose module provides an ODM for MongoDB, Express extends Node’s HTTP capabilities, and so on.

Node.js modules are created by various third-party organizations to provide important features that Node.js lacks out of the box. This community of contributors is very active in adding and updating modules.

Each Node Packaged Module includes a package.json file that defines the packages. The package.json file includes informational metadata such as the name, version, author, and contributors, as well as control metadata such as dependencies and other requirements that the Node Package Manager will use when performing actions such as installation and publishing.
