How many people use param-case?
npm counted 35,655,461 downloads of param-case 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 35.6M–35.7M look like real installs. At this scale most of them come from CI, builds and other packages that depend on param-case, so the number of people behind them is far smaller.
Is param-case still maintained?
No: the latest version is marked deprecated on npm, with the message “Use `change-case`”. The latest version, 4.0.0, came out on Sep 30, 2023. There were no stable releases in the last 12 months. It was first published on Mar 24, 2014. npm lists 1 maintainer.
Is param-case still used?
Downloads with publish spikes removed are up 13% over 3 months and up 53% 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 behind that. Last week, 83% of downloads above the crawler floor were on major version 3, not the latest one; the most used single version was 3.0.4, with 83%. Weekdays get 2.1× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 204 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.
