pkgcount

pkgcount

Easily see how many packages, which versions and how many copies of each package are installed in your node_modules hierarchy.

Installation

npm install -g pkgcount

Usage

> pkgcount --help
  Usage: pkgcount [options]

  Options:

    -h, --help             output usage information
    -V, --version          output the version number
    -m, --min [count]      only list packages duplicated at least this number of times
    -d, --duplicates       only list packages appearing more than once
    --json                 display json output
    --no-color             display uncolored output. Colors indicate packages with high levels of duplication
    --paths                list paths to each package instead of counts
    --summary              only display summary
    --depth [depth]        limit traversal depth
    -s, --sort-duplicates  Sort results by number of duplicates

By default, pkgcount uses coloured output as a simple visual aide to help identify packages with high levels of duplication. Packages are shaded from yellow->red based on the number of duplicates.
