libnpmaccess is a Node.js library that provides programmatic access to the guts of the npm CLI's npm access command. This includes managing account mfa settings, listing packages and permissions, looking at package collaborators, and defining package permissions for users, orgs, and teams.

const access = require('libnpmaccess')
const opts = { '//registry.npmjs.org/:_authToken: 'npm_token }

// List all packages @zkat has access to on the npm registry.
console.log(Object.keys(await access.getPackages('zkat', opts)))

libnpmaccess uses npm-registry-fetch.

All options are passed through directly to that library, so please refer to its own opts documentation for options that can be passed in.
