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 package is a directory with one or more modules inside of it and a package.json file wich has metadata about the package.
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
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.
In the Node.js module system, each file is treated as a separate module.
npm has some official def here.
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:
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.
Introducing Package Diff - intrinsic, Table of Contents. Modules. Accessing the main module; Addenda: Package In the Node.js module system, each file is treated as a separate module. The main property of a package.json is a direction to the entry point to the module that the package.json is describing. In a Node.js application, when the module is called via a require statement, the module's exports from the file named in the main property will be what's returned to the Node.js application.
