Fetch stats for your NPM packages

This package makes it easy to retrieve stats for packages hosted on npmjs.com

PS: It's heavily inspired by the packagist-api package made from Spatie

Installation

You can install the package via composer:

composer require developmint/npm-stats-api

Usage

You must pass a Guzzle client to the constructor of Developmint\NpmStats\NpmStats.

$client = new \GuzzleHttp\Client();

$npmStats = new \Developmint\NpmStats\NpmStats($client);

Get stats for a package of your choice

$npmStats->getStats('jquery');

Get stats with a period of your choice

Use a constant provided by the NpmStats class to get stats for the last day, week, month, year or in total.

$npmStats->getStats('jquery', NpmStats::LAST_DAY);

You can also pass in specific dates

$npmStats->getStats('jquery', '2017-01-01');

Or even ranges

$npmStats->getStats('jquery', '2014-02-07:2014-02-14');

The output will be already decoded from json:

array(4) {
  ["downloads"]=>
  int(198672)
  ["start"]=>
  string(10) "2017-10-10"
  ["end"]=>
  string(10) "2017-10-10"
  ["package"]=>
  string(6) "jquery"
}

Get stats with a period of your choice as range

You can also get the stats as a range, means the downloads split up per day:

$npmStats->getStats('jquery', NpmStats::LAST_WEEK, true);

And this would be the result of that call:

array(4) {
  ["start"]=>
  string(10) "2017-10-04"
  ["end"]=>
  string(10) "2017-10-10"
  ["package"]=>
  string(6) "jquery"
  ["downloads"]=>
  array(7) {
    [0]=>
    array(2) {
      ["downloads"]=>
      int(200678)
      ["day"]=>
      string(10) "2017-10-04"
    }
    [1]=>
    array(2) {
      ["downloads"]=>
      int(195593)
      ["day"]=>
      string(10) "2017-10-05"
    }
    [2]=>
    array(2) {
      ["downloads"]=>
      int(172132)
      ["day"]=>
      string(10) "2017-10-06"
    }
    [3]=>
    array(2) {
      ["downloads"]=>
      int(51068)
      ["day"]=>
      string(10) "2017-10-07"
    }
    [4]=>
    array(2) {
      ["downloads"]=>
      int(46892)
      ["day"]=>
      string(10) "2017-10-08"
    }
    [5]=>
    array(2) {
      ["downloads"]=>
      int(171920)
      ["day"]=>
      string(10) "2017-10-09"
    }
    [6]=>
    array(2) {
      ["downloads"]=>
      int(198672)
      ["day"]=>
      string(10) "2017-10-10"
    }
  }
}

Get bulk stats

Of course you can retrieve up to 128 packages as a bulk query. Simply separate them with a command and you are good to go.

$npmStats->getStats('vue,express', NpmStats::LAST_WEEK);

But beware! This only works in point mode, not in range mode.

$npmStats->getStats('vue,express', NpmStats::LAST_WEEK, true);
//Won't work

Anyway, the output will look similar to the normal point mode output:

array(2) {
  ["vue"]=>
  array(4) {
    ["downloads"]=>
    int(3980980980098089080980983)
    ["package"]=>
    string(5) "vue"
    ["start"]=>
    string(10) "2017-10-10"
    ["end"]=>
    string(10) "2017-10-10"
  }
  ["express"]=>
  array(4) {
    ["downloads"]=>
    int(818264)
    ["package"]=>
    string(7) "express"
    ["start"]=>
    string(10) "2017-10-10"
    ["end"]=>
    string(10) "2017-10-10"
  }
}
