hacker-deps

Print the list of hackers your application depends on.

hacker-deps finds all package.json files and finds who wrote each non-private package depended on in your application.

In this list the percentage is a normalized sum of all the packages in the dependency graph weighted by distance to give a rough estimate of how reliant your application is on the work of each hacker in the results.

To supplement the list of hackers with lists of packages, add --verbose:

$ hacker-deps ~/projects/substack.net --verbose | head -n30

You can also print the list of modules ranked by module score with --modules:

$ hacker-deps ~/projects/substack.net --modules | head -n20
findit      12.0 %  James Halliday (substack)
hyperquest  12.0 %  James Halliday (substack)
walk-fs     12.0 %  skoni (skoni)

text-table  12.0 %  James Halliday (substack)
through      6.0 %  Dominic Tarr (dominictarr)
duplexer     6.0 %  Raynos (Raynos)
seq          6.0 %  James Halliday (substack)
wordwrap     6.0 %  James Halliday (substack)
minimist     6.0 %  James Halliday (substack)
traverse     4.0 %  James Halliday (substack)

usage

usage: hacker-deps OPTIONS

OPTIONS are:

  -v, --verbose     Verbose module output for the default output mode
  -m, --modules     List the normalized weights of each module used.
  -b, --budget      Hypothetical amount to budget for open source.
  -s, --socialism   Coefficient of socialism for --budget (default: 1.5)

methods

var hdeps = require('hacker-deps')

hdeps(root, cb)

Compute the hacker dependencies starting at the application path root.

cb(err, hackers) fires once the complete graph has been traced with hackers, an array of entries sorted by a contribution score. Each row looks like:

{
  name: 'Dominic Tarr',
  github: 'dominictarr',
  packages: {
    split: 1.5,
    through: 3.1666666666666665,
    'vec2-dom': 1,
    'vec2-layout': 2,
    example: 2,
    rec2: 0.5,
    hyperscript: 0.5
  },
  score: 0.24436807941962585
}

The score is a normalized contribution score that shows how reliant your application is on this author.

The packages object is non-normalized package data according to the sum of 1/(2 * distance) where distance is the number of dependencies up the dependency hierarchy. The assumption here is that modules that are further away are probably less crucial to your application.

install
