libnpmaccess

What is libnpmaccess?

The libnpmaccess package is a Node.js library that provides programmatic access to the npm access control features. It allows you to manage package access permissions, such as granting or revoking access to npm packages for different users or teams.

What are libnpmaccess's main functionalities?

Grant Access

This feature allows you to grant access to a specific npm package for a user or team. In the code sample, 'read-write' access is granted to 'my-package' for the user 'username'.

const access = require('libnpmaccess');

async function grantAccess() {
  await access.grant('read-write', 'my-package', 'user:username');
  console.log('Access granted');
}

grantAccess();

Revoke Access

This feature allows you to revoke access to a specific npm package for a user or team. In the code sample, access to 'my-package' is revoked for the user 'username'.

const access = require('libnpmaccess');

async function revokeAccess() {
  await access.revoke('my-package', 'user:username');
  console.log('Access revoked');
}

revokeAccess();

List Access

This feature allows you to list the access permissions for a specific npm package. In the code sample, the access permissions for 'my-package' are listed.

const access = require('libnpmaccess');

async function listAccess() {
  const accessList = await access.lsPackages('my-package');
  console.log(accessList);
}

listAccess();

Other packages similar to libnpmaccess

npm

The npm package itself provides CLI commands for managing access control, such as `npm access grant` and `npm access revoke`. While libnpmaccess offers programmatic access, the npm package is more suited for command-line operations.

np

The np package is a streamlined tool for publishing npm packages. It includes some access control features but is primarily focused on simplifying the publishing process. It does not offer the same level of granularity in access control as libnpmaccess.

npm-cli-login

The npm-cli-login package is used for programmatically logging into npm. While it does not manage access control, it is often used in conjunction with other tools that do. It complements libnpmaccess by handling authentication.

README

libnpmaccess

libnpmaccess is a Node.js library that provides programmatic access to the guts of the npm CLI's npm access command and its various subcommands. This includes managing account 2FA, listing packages and permissions, looking at package collaborators, and defining package permissions for users, orgs, and teams.

Example

const access = require('libnpmaccess')

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

API

opts for libnpmaccess commands

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.

A couple of options of note for those in a hurry:

• opts.token - can be passed in and will be used as the authentication token for the registry. For other ways to pass in auth details, see the n-r-f docs.
• opts.otp - certain operations will require an OTP token to be passed in. If a libnpmaccess command fails with err.code === EOTP, please retry the request with {otp: <2fa token>}
• opts.Promise - If you pass this in, the Promises returned by libnpmaccess commands will use this Promise class instead. For example: {Promise: require('bluebird')}

> access.public(spec, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec.

Makes package described by spec public.

Example

await access.public('@foo/bar', {token: 'myregistrytoken'})
// `@foo/bar` is now public

> access.restricted(spec, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec.

Makes package described by spec private/restricted.

Example

await access.restricted('@foo/bar', {token: 'myregistrytoken'})
// `@foo/bar` is now private

> access.grant(spec, scope, team, permissions, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec. scope must be a valid scope, with or without the @ prefix, and team must be a valid team within that scope. permissions must be one of 'read-only' or 'read-write'.

Grants read-only or read-write permissions for a certain package to a team.

Example

await access.grant('@foo/bar', '@foo', 'myteam', 'read-write', {
  token: 'myregistrytoken'
})
// `@foo/bar` is now read/write enabled for the @foo:myteam team.

> access.revoke(spec, scope, team, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec. scope must be a valid scope, with or without the @ prefix, and team must be a valid team within that scope. permissions must be one of 'read-only' or 'read-write'.

Removes access to a package from a certain team.

Example

await access.revoke('@foo/bar', '@foo', 'myteam', {
  token: 'myregistrytoken'
})
// @foo:myteam can no longer access `@foo/bar`

> access.tfaRequired(spec, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec.

Makes it so publishing or managing a package requires using 2FA tokens to complete operations.

Example

await access.tfaRequires('lodash', {token: 'myregistrytoken'})
// Publishing or changing dist-tags on `lodash` now require OTP to be enabled.

> access.tfaNotRequired(spec, [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec.

Disabled the package-level 2FA requirement for spec. Note that you will need to pass in an otp token in opts in order to complete this operation.

Example

await access.tfaNotRequired('lodash', {otp: '123654', token: 'myregistrytoken'})
// Publishing or editing dist-tags on `lodash` no longer requires OTP to be
// enabled.

> access.lsPackages(scope, [team], [opts]) -> Promise

scope must be a valid org or user name, with or without the @ prefix. team is optional and, if provided, must be a valid team within that scope. team must be null in order to pass in opts.

Lists out packages a user, org, or team has access to, with corresponding permissions. Packages that the access token does not have access to won't be listed.

For a streamed version of these results, see access.lsPackages.stream().

Example

await access.lsPackages('zkat', null, {
  token: 'myregistrytoken'
})
// Lists all packages `@zkat` has access to on the registry, and the
// corresponding permissions.

> access.lsPackages.stream(scope, [team], [opts]) -> Stream

scope must be a valid org or user name, with or without the @ prefix. team is optional and, if provided, must be a valid team within that scope. team must be null in order to pass in opts.

Streams out packages a user, org, or team has access to, with corresponding permissions, with each stream entry being formatted like [packageName, permissions]. Packages that the access token does not have access to won't be listed.

The returned stream is a valid asyncIterator.

Example

for await (let [pkg, perm] of access.lsPackages.stream('zkat')) {
  console.log('zkat has', perm, 'access to', pkg)
}
// zkat has read-write access to eggplant
// zkat has read-only access to @npmcorp/secret

> access.lsCollaborators(spec, [user], [opts]) -> Promise

spec must be an npm-package-arg-compatible registry spec. scope must be a valid org or user name, with or without the @ prefix. team is optional and, if provided, must be a valid team within that scope. team must be null in order to pass in opts.

Lists out access privileges for a certain package. Will only show permissions for packages to which you have at least read access. If user is passed in, the list is filtered only to teams that user happens to belong to.

For a streamed version of these results, see access.lsCollaborators.stream().

Example

await access.lsCollaborators('@npm/foo', 'zkat', {
  token: 'myregistrytoken'
})
// Lists all teams with access to @npm/foo that @zkat belongs to.

> access.lsCollaborators.stream(spec, [user], [opts]) -> Stream

spec must be an npm-package-arg-compatible registry spec. scope must be a valid org or user name, with or without the @ prefix. team is optional and, if provided, must be a valid team within that scope. team must be null in order to pass in opts.

Stream out access privileges for a certain package, with each entry in [user, permissions] format. Will only show permissions for packages to which you have at least read access. If user is passed in, the list is filtered only to teams that user happens to belong to.

The returned stream is a valid asyncIterator.

Example

for await (let [usr, perm] of access.lsCollaborators.stream('npm')) {
  console.log(usr, 'has', perm, 'access to npm')
}
// zkat has read-write access to npm
// iarna has read-write access to npm
