I am Node noob. What is the difference between a "package" and a "module" in Node.js?

About packages and modules, There is one to one mapping between module and a JS file which means each file is simply a module. Like File1.JS, File2.JS, all these are considered as modules. Answers: Every Node app is a package, and should have a package.json file. Those apps that act as middleware (or the equivalent of libraries), and are meant to be installed inside other apps are modules. In short all modules are packages, but not all packages are meant to be used as modules, though many can be.

Modules will be installed, if listed as dependencies in the package.json file, and placed into the node_modules folder, but npm recurses through their package.json files to add the modules they rely on.

What is the difference between Node modules and package.json , I am Node noob. What is the difference between a "package" and a "module" in Node.js? Modules are libraries for node.js. See the below excerpt from the api:  A module is any file or directory in the node_modules directory that can be loaded by the Node.js require() function. To be loaded by the Node.js require() function, a module must be one of the following:

A module is a single JavaScript file that has some reasonable functionality.

A package is a directory with one or more modules inside of it and a package.json file wich has metadata about the package.

A package can be very simple for example, underscore just has a single Javascript file (we see two versions of it regular and minified version and package.json)

open@open-PC MINGW64 ~/Desktop/module-package-demo/node_modules/underscore
$ dir
LICENSE       README.md      underscore-min.js
package.json  underscore.js  underscore-min.js.map

Whereas a more complex package like Express has one Javascript file in the root but inside its sub-directories has quite a few more Javascript files and more within sub-directories of that

open@open-PC MINGW64 ~/Desktop/module-package-demo/node_modules/express
$ dir
History.md  index.js  lib  LICENSE  package.json  Readme.md

Now it's very common for people to refer to a package as a module.

Difference between a module and a package in Node?, James shows how to work with modules in Node.js, focusing on how to export and consume them, and explaining the difference between  There is one to one mapping between module and a JS file which means each file is simply a module. Like File1.JS, File2.JS, all these are considered as modules. Whereas package is a collection of files or modules grouped together. It is reusable code which developers can download in their local development environment.

Quick Summary A package is a file or directory that is described by a package.json. This can happen in a bunch of different ways! For more info, see "What is a package?, below. A module is any file or directory that can be loaded by Node.js' require(). Again, there are several configurations that allow this to happen. For more info, see "What is a module?", below.

Understanding module.exports and exports in Node.js, It is also commonly used to install a wide range of CLI tools and run project scripts. npm tracks the modules installed in a project with the package. The Node.js Package Manager (npm) is the default and most popular package manager in the Node.js ecosystem, and is primarily used to install and manage external modules in a Node.js project. It is also commonly used to install a wide range of CLI tools and run project scripts. npm tracks the modules installed in a project with the package.json

Everything what you can require() is a module. In most cases in the CommonJS world it's one file is a module.

A package can contain several modules, but you usually loading the entry point (main), which is specified in the package.json or it's index.js if no main property is provided, for instance: require('express')

But you can also require another file (not the main file) if you know the location, for instance: require("express/lib/application") (in node.js you can omit the extension: .js)

A package can access modules from other packages if they are listed in the dependencies property of the package.json.

Actually npm installs all the packages into node_modules which is confusing, because it should be node_packages.
