What is a npm package?

In general, Npm package is a folder containing a program described by a package.json file.

The folder usually contains files with source code, assets (images, videos, CSS files), documentation and other files.

• A package can also be called a module.

When someone refers to a package, he usually thinks about the folder with source files. However, the packages can be distributed in different forms:

• A package can be distributed as a gzipped archive.
• A package can be also a URL that points to gzipped archive.

For that reason, the package locaiton can be represented by

• Local path to a folder
• Local path to a gzipped archive
• URL to a gzipped archive
