Easily see how many packages, which versions and how many copies of each package are installed in your node_modules hierarchy.
npm install -g pkgcount
> 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.
