Name

The most important thing in package.json is the name and version fields. They are all necessary, if you don't have it you cannot install. The identifier composed of name and version is unique in the hypothesis. Changing the package should also change the version.

name is the name of this thing. note:

Don't put node or js in the name.

Version

The version must be parsed by node-semver, and it is packaged in npm's dependencies. (If you want to use it yourself, you can execute npm install semver)
