Why this estimate
With JavaScript on, this lists what the filter found for this package.
Most used major version: 26, not the latest one, with 20% of last week's downloads above the crawler floor. Most used single version: 26.1.0.
Snapshot from the daily build of Nov 6, 2026, last 7 days of npm data. With JavaScript on, this page recomputes it live from the npm API.
How many people use jsdom?
npm counted 152,802,777 downloads of jsdom in the last 7 days. Nobody can count people exactly, npm included: it does not record who downloaded what. After removing mirror spikes and crawlers, about 153M look like real installs. At this scale most of them come from CI, builds and other packages that depend on jsdom, so the number of people behind them is far smaller.
Is jsdom still maintained?
Most likely yes, going by its releases. The latest version, 31.0.0, came out on Nov 5, 2026. The last 12 months saw 17 stable releases, typically 18 days apart. It was first published on Nov 21, 2011. npm lists 6 maintainers.
Is jsdom still used?
Downloads with publish spikes removed are up 63% over 3 months and up 265% over 11 months. For scale, the median of the 269 packages we track, which lean towards today's most downloaded, is up 157% over 11 months, so this one is ahead of that. Last week, 20% of downloads above the crawler floor were on major version 26, not the latest one; the most used single version was 26.1.0, with 19%. Weekdays get 1.5× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 3,480 downloads a week, roughly 12 per version.
How the estimate works
- Cut the spike every new version gets from mirrors in its first days.
- Subtract the flat floor robots download from every version each week.
- Show what is left as a range, with a confidence level. It still includes CI and dependency installs, so it is not a count of people.
