What packages can be found in NPM?

According to the definitions of survivejs and npmjs; we can say: A minimal npm package should contain metadata in a package.json file and an associated source file (usually index.js). In practice, packages contain more than that and you will have at least a license file and the source in various formats.

Often projects contain more files than are required to execute them; A package is a file or directory that is described by a package.json file; A package must contain a package.json file in order to be published to the npm registry.

Packages can be unscoped or scoped to a user or organization, and scoped packages can be private or public!
