libnpmpack
Advanced tools
libnpmpack is a Node.js library for
programmatically packing tarballs from a local directory or from a registry or github spec. If packing from a local source, libnpmpack will also run the prepack and postpack lifecycles.
const pack = require('libnpmpack')
$ npm install libnpmpack
> pack(spec, [opts]) -> PromisePacks a tarball from a local directory or from a registry or github spec and returns a Promise that resolves to the tarball data Buffer, with from, resolved, and integrity fields attached.
If no options are passed, the tarball file will be saved on the same directory from which pack was called in.
libnpmpack uses pacote.
Most options are passed through directly to that library, so please refer to
its own opts
documentation
for options that can be passed in.
// packs from cwd
const tarball = await pack()
// packs from a local directory
const localTar = await pack('/Users/claudiahdz/projects/my-cool-pkg')
// packs from a registry spec
const registryTar = await pack('abbrev@1.0.3')
// packs from a github spec
const githubTar = await pack('isaacs/rimraf#PR-192')
