Pkgcount NPM | npm.io

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
    -D, --du           show disk usage
    --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 [key]   Sort results by (name|duplicates|size) [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.
