counts( options, clbk )

Get an author's package download counts.

var opts = {
    'username': 'kgryte'
};

counts( opts, clbk );

function clbk( error, data ) {
    if ( error ) {
        throw error;
    }
    console.dir( data );
    /*
        [
            {
                "package": "app-boot",
                "data": [
                    ["2015-12-01T00:00:00.000Z",3295],
                    ["2015-12-02T00:00:00.000Z",5498],
                    ["2015-12-03T00:00:00.000Z",4771],
                    ...
                ]
            },
            {
                "package": "app-etc",
                "data": [
                    ["2015-12-01T00:00:00.000Z",1003],
                    ["2015-12-02T00:00:00.000Z",809],
                    ["2015-12-03T00:00:00.000Z",946],
                    ...
                ]
            },
            ...
        ]
    */
}

The function accepts the following options:

• username: author username (required).
• period: query period. May be either a keyword (e.g., 'last-month', 'last-week', 'last-day') or a date range (e.g., '2015-12-01:2016-01-01'). Default: 'last-month'.

By default, the function returns daily downloads for the last month. To return daily downloads for an alternative period, set the period option.

var opts = {
    'username': 'kgryte',
    'period': '2015-11-01:2015-12-31'
};

counts( opts, clbk );

counts.factory( options, clbk )

Creates a reusable function.

var get = counts.factory( {'username':'kgryte'}, clbk );

get();
get();
get();
// ...

The factory method accepts the same options as counts().

Notes

• If the module encounters an application-level error (e.g., no network connection, malformed request, etc), that error is returned immediately to the provided callback.
• Time values are in simplified ISO format (ISO 8601).
• A query period is not sanity checked. If counts are expected, ensure that the provided period is of the appropriate format and/or a recognized value.

Examples

var counts = require( 'npm-author-download-counts' );

var opts = {
    'username': 'kgryte'
};

counts( opts, onCounts );

function onCounts( error, data ) {
    if ( error ) {
        throw error;
    }
    console.dir( data );
}

To run the example code from the top-level application directory,

$ DEBUG=* node ./examples/index.js

CLI

Installation

To use the module as a general utility, install the module globally

$ npm install -g npm-author-download-counts

Usage

Usage: apkgcounts [options] username

Options:

  -h,  --help                 Print this message.
  -V,  --version              Print the package version.
       --period period        Query period. May be either a keyword (e.g.,
                              'last-month','last-week','last-day') or a date
                              range (e.g., '2015-12-01:2016-01-01'). Default:
                              'last-month'.
       --format format        Output format: csv or json. Default: 'csv'.
       --delimiter delimiter  CSV column delimiter. Default: ','.

Notes

• If the output format is csv and the process is unable to resolve counts, the process will write an error message to stderr and will not generate CSV output.

Examples

$ DEBUG=* apkgcounts kgryte
# => time,app-boot,app-etc
# => 2015-12-01T00:00:00.000Z,3295,1003
# => 2015-12-02T00:00:00.000Z,5498,809
# => 2015-12-03T00:00:00.000Z,4771,946
# => ...

To output as newline-delimited JSON (ndjson), set the format option.

$ DEBUG=* apkgcounts --format=json kgryte
# => {"app-boot":[[...],[...],...]}
# => {"app-etc":[[...],[...],...]}

Tests

Unit

This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov

Browser Support

This repository uses Testling for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:

$ make test-browsers

To view the tests in a local web browser,

$ make view-browser-tests
