npm-download-counts

Fetch package download counts for packages from the npm registry

const moment = require('moment')
const downloadCounts = require('npm-download-counts')

const pkg = 'levelup'
const start = moment().subtract('months', 1).toDate() // start date for lookup
const end = new Date() // end date for lookup

let data = await downloadCounts(pkg, start, end)
// `data` is an array of objects with `day` and `count` properties
// each element of the array represents a day in your date range
data.forEach(function (d, i) {
  console.log(`On ${d.day}, ${pkg} was downloaded ~${d.count} times`)
})

Gives you something like:

On 2013-06-15, levelup was downloaded ~91 times
On 2013-06-16, levelup was downloaded ~47 times
On 2013-06-17, levelup was downloaded ~57 times
On 2013-06-18, levelup was downloaded ~141 times
