How many people use phantomjs-prebuilt?
npm counted 411,570 downloads of phantomjs-prebuilt 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 410K–412K look like real installs. Noise is under 1% of npm's count. What remains still includes CI and installs as a dependency of other packages.
Is phantomjs-prebuilt still maintained?
No: the latest version is marked deprecated on npm, with the message “this package is now deprecated”. The latest version, 2.1.16, came out on Nov 2, 2017. There were no stable releases in the last 12 months. It was first published on Jan 27, 2016. npm lists 3 maintainers.
Is phantomjs-prebuilt still used?
Downloads with publish spikes removed are down 5% over 3 months and about flat 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, 100% of downloads above the crawler floor were on major version 2, the latest one; the most used single version was 2.1.16, with 92%. Weekdays get 1.6× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 54 downloads a week, roughly 3 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.
