An npm registry follower that calculates (and recalculates) flat package dependency manifests for each registry update. Users can query the manifest of any package at any version at any CouchDB-style update sequence number.

WARNING: Highly experimental dilettante technology! Any resemblance to real, usable npm package dependency graphs is purely coincidental.

Flat package manifests are shaped like:

[
  // "Dependency Records"
  {
    name: String,
    version: String, // SemVer version or URL
    // Optional.  Indicates the package is a direct dependency.
    range: String, // SemVer range or URL
    links: [
      // "Link Records"
      {
        name: String,
        version: String, // SemVer version or URL
        range: String // SemVer range or URL
      }
      // ...
    ]
  }
  // ...
]

The package ships with a bin script that starts following the public registry and serves data via HTTP.

Useful request paths include:

• GET /package/$name/$version/$sequence, where /$sequence is the server's current sequence by default. Serves a flat dependency tree, if any, as JSON.

• GET /sequence serves the server's current sequence number.
