ncm-analyze-tree

ncm-analyze-tree

Get certification data for a module's dependency tree, as it is on disk.

This process is optimized by trying to get all the necessary information from a package-lock.json or yarn.lock file, and a full scan of node_modules/** is only reverted to if no lock file exists.

Usage

Print certification data for this module's dependency tree:

const analyze = require('ncm-analyze-tree')

const data = await analyze({
  dir: __dirname,
  token: 'accounts token',
  onPkgs: pkgs => console.log(`Analyzing ${pkgs.size} modules...`)
})

for (const pkg of data) {
  console.log(`${pkg.name}@${pkg.version}`)
  for (const path of pkg.paths) {
    console.log(`  ${path.map(pkg => `${pkg.data.name}@${pkg.data.version}`).join(' > ')}`)
  }
}
