What is the users object in npm registry json response?

Question

For the json response for any npm package. In jQuery for example, http://registry.npmjs.org/jquery there exists a dictionary users with some usernames as keys and a boolean value as the value.

"users": {
    "dodo": true,
    "fgribreau": true,
    "parroit": true,
    "cedx": true,
    "bendiken": true,
    "funroll": true
}

What is this user dictionary? I couldn't find any reference about it. If someone could explain?

Thank You.

Answer 1

According to the npm registry docs

users an object whose keys are the npm user names of people who have starred this package

A description for what starring is can be found here

"Starring" a package means that you have some interest in it. It's a vaguely positive way to show that you care.

"Unstarring" is the same thing, but in reverse.

It's a boolean thing. Starring repeatedly has no additional effect.
