River of CPAN

The River of CPAN assigns each CPAN distribution a position based on how many other distributions depend on it, both directly and transitively.

This repository generates a nightly JSON snapshot of river data for every distribution on CPAN which has a status of "latest" and publishes it to GitHub Pages.

The nightly JSON will be used by MetaCPAN to provide river position numbers on dist and module pages. If you think those numbers are incorrect, this is the place to supply a fix.

The JSON is keyed by distribution name:

{
  "Moose": {
    "immediate": 123,
    "total": 5678,
    "bucket": 4
  }
}

Fields

• immediate — number of distributions that directly depend on this one
• total — number of distributions that depend on it directly or transitively
• bucket — river position (0–5) based on log10 of total:
  • 0: total = 0
  • 1: total 1–9
  • 2: total 10–99
  • 3: total 100–999
  • 4: total 1000–9999
  • 5: total 10000+
