@vltpkg/dep-id

A library for serializing dependencies into terse string identifiers, and turning those serialized identifiers back into Spec objects.

Usage

import {
  getId,
  getTuple,
  hydrate,
  hydrateTuple,
  joinDepIDTuple,
  splitDepID,
} from '@vltpkg/dep-id'
import { manifest } from '@vltpkg/package-info'

{
  // default registry
  const spec = Spec.parse('x@latest')
  const mani = await manifest(spec)
  const id = getId(spec, mani) // registry;;x@1.2.3
}

{
  // not default registry
  const spec = Spec.parse('x@vlt:y@latest', {
    registries: { vlt: 'http://vlt.sh' },
  })
  const mani = await manifest(spec)
  const id = getId(spec, mani) // registry;vlt;y@latest
}

{
  // git, hosted
  const spec = Spec.parse('x@github:a/b#branch')
  const mani = await manifest(spec)
  const id = getId(spec, mani) // git;github:a/b;branch
}

// Hydrate by providing a name, and options for the spec creation
const spec = hydrate('git;github:a/b;branch', 'x') // x@github:a/b#branch

Note

multiple different spec/manifest combinations can result in the same identifier. For example, the specifiers x@npm:y@latest and asdf@npm:y@1.x might both ultimately resolve to the same package, so they only need to appear in the store once.

BROWSER API

An isomorphic API @vltpkg/dep-id/browser is provided for use in the browser.
