Downloads total is not correct

Recently I’m digging more and more around the statistics of my most (that I know) used packages, and seeing that the downloads badge isn’t showing correct information. Not sure if it’s only the total downloads badge though.

For example, the badge https://badgen.net/npm/dt/formidable for formidable is showing 170M, but it’s around 312M - https://twitter.com/tunnckoCore/status/1225150205982662657.

Today I’m seeing such mismatches with koa-better-body (600K, shows 329K), parse-function (2.7M, shows 35K) and get-installed-path is most close (2.1M, shows 1.7), and more. I’m looking on https://npm-stat.com

I can look around when get some time.

Download counts before 2015-2-27 is lost:

https://api.npmjs.org/downloads/range/2000-1-1:2015-12-31/express (born in 2010) https://api.npmjs.org/downloads/range/2000-1-1:2015-12-31/npm (hits 1.0 in 2011)

The NPM API returns the last 18 months as the maximum range - you’ll need to do multiple queries for each 18 month period.

In addition, it looks like the api reports data starting from 2015-1-10 (not 2005-1-1): https://api.npmjs.org/downloads/range/2000-1-1:2015-1-31/express
