libnpmpublish
libnpmpublish is a Node.js
library for programmatically publishing and unpublishing npm packages. Give
it a manifest as an object and a tarball as a Buffer, and it'll put them on
the registry for you.

API
opts for libnpmpublish commands
libnpmpublish uses
npm-registry-fetch. Most 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:
opts.defaultTag- registers the published package with the given tag, defaults tolatest.opts.access- tells the registry whether this package should be published aspublicorrestricted. Only applies to scoped packages. Defaults topublic.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.provenance- when running in a supported CI environment, will trigger the generation of a signed provenance statement to be published alongside the package. Mutually exclusive with theprovenanceFileoption.opts.provenanceFile- specifies the path to an externally-generated provenance statement to be published alongside the package. Mutually exclusive with theprovenanceoption. The specified file should be a Sigstore Bundle containing a DSSE-packaged provenance statement.
> libpub.publish(manifest, tarData, [opts]) -> Promise
Sends the package represented by the manifest and tarData to the
configured registry.
manifest should be the parsed package.json for the package being
published (which can also be the manifest pulled from a packument, a git
repo, tarball, etc.)
tarData is a Buffer of the tarball being published.
If opts.npmVersion is passed in, it will be used as the _npmVersion
field in the outgoing packument. You may put your own user-agent string in
there to identify your publishes.
If opts.algorithms is passed in, it should be an array of hashing
algorithms to generate integrity hashes for. The default is ['sha512'],
which means you end up with dist.integrity = 'sha512-deadbeefbadc0ffee'.
Any algorithm supported by your current node version is allowed -- npm
clients that do not support those algorithms will simply ignore the
unsupported hashes.
Example
// note that pacote.manifest() and pacote.tarball() can also take
// any spec that npm can install. a folder shown here, since that's
// far and away the most common use case.
const path = '/a/path/to/your/source/code'
const pacote = require('pacote') // see: http://npm.im/pacote
const manifest = await pacote.manifest(path)
const tarData = await pacote.tarball(path)
await libpub.publish(manifest, tarData, {
npmVersion: 'my-pub-script@1.0.2',
token: 'my-auth-token-here'
}, opts)
// Package has been published to the npm registry. > libpub.unpublish(spec, [opts]) -> Promise
Unpublishes spec from the appropriate registry. The registry in question may
have its own limitations on unpublishing.
spec should be either a string, or a valid
npm-package-arg parsed spec object. For
legacy compatibility reasons, only tag and version specs will work as
expected. range specs will fail silently in most cases.
Example
await libpub.unpublish('lodash', { token: 'i-am-the-worst'})
//
// `lodash` has now been unpublished, along with all its versions
