How many people use os-tmpdir?
npm counted 27,779,782 downloads of os-tmpdir 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 27.8M look like real installs. At this scale most of them come from CI, builds and other packages that depend on os-tmpdir, so the number of people behind them is far smaller.
Is os-tmpdir still maintained?
No: the latest version is marked deprecated on npm, with the message “This is not needed anymore. `require('os').tmpdir()` in Node.js 4 and up is good.”. The latest version, 2.0.0, came out on Nov 8, 2018. There were no stable releases in the last 12 months. It was first published on May 7, 2015. npm lists 1 maintainer.
Is os-tmpdir still used?
Downloads with publish spikes removed are up 11% over 3 months and up 8% over 11 months. For scale, the median of the 384 packages we track, which lean towards today's most downloaded, is up 164% over 11 months, so this one is behind that. Last week, 100% of downloads above the crawler floor were on major version 1, not the latest one; the most used single version was 1.0.2, with 100%. Weekdays get 2.0× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 3,900 downloads a week, roughly 975 per version.
Monthly downloads of os-tmpdir
The busiest month was Sep 2026, with about 3,955,430 downloads a day once publish spikes are removed; the quietest was Jan 2026, with about 2,893,058.

Whole months through Oct 31, 2026. Publish spikes are found day by day and summed per month. Real installs apply this week's crawler share to each month's downloads (the upper end also keeps the removed spikes), so they follow npm's curve rather than measure it. The change compares spike-free downloads per day.
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.
