Why use this

API-only — official npm registry JSON (no HTML scraping)
Delta-only — subsequent runs emit new versions only
First-run safe — empty state seeds LAST_SEEN with zero PPE delta charges
No auth required for public packages
Schedule-friendly — pair with an Apify schedule for continuous monitoring
Scoped packages supported (@scope/name)

Input

Field	Required	Description
`packages`	yes	List of npm package names (incl. scoped)
`sinceVersion`	no	On first run for a package, treat this version and older (by publish time) as already seen
`includePrereleases`	no	Include semver prereleases (default true)
`resetState`	no	Clear `LAST_SEEN` and re-baseline (0 emits that run)

Example

{
  "packages": ["lodash", "axios", "@apify/utilities"],
  "includePrereleases": true,
  "resetState": false
}

Output

Each dataset item is a newly detected version, for example:

package, version, published_at, package_description, is_prerelease, is_latest, registry_url, tarball_url

First-run behavior

Situation	Dataset items	`version-delta` charges
Empty state, no `sinceVersion`	0	0 (baseline only)
Empty state + `sinceVersion`	Only newer than that version	1 per item
Later runs	New version strings only	1 per item

Tips

Run once to baseline, then attach a schedule (e.g. hourly/daily).
Keep package lists focused — each packument fetch is one HTTP GET.
Set a user max total charge on the run so costs stay predictable.

ToS / scope

Uses the public npm registry REST API only. See ./AGREEMENT.md. Respect npm registry terms and fair use.
