Tests NPM version

Shows how fat is a package together with its dependencies

howfat

Usage

Simple

Specified version or version range:

npx howfat mkdirp@^0.5.0

Local packages

cd my-project
npx howfat

npx howfat ../my-other-package

Git or github

npx howfat ssh://[email protected]:substack/node-mkdirp.git#0.3.4

Different reporters

Just show a simple stats:

$ npx howfat -r simple [email protected]
Dependencies: 1
Size: 41.49kb
Files: 37

as a table:

$ npx howfat -r table [email protected]
[email protected] (1 dep, 41.49kb, 37 files)
╭────────────────┬──────────────┬─────────┬───────╮
│ Name           │ Dependencies │    Size │ Files │
├────────────────┼──────────────┼─────────┼───────┤
│ [email protected] │            0 │ 20.78kb │    14 │
╰────────────────┴──────────────┴─────────┴───────╯

as a json:

$ npx howfat -r json [email protected] --space 2

Accuracy

Different package managers use different dependency resolution algorithms. Even different versions of the same manager will resolve different dependency tree. So, this package tries to calculate stats similar to npm, but keep in mind that it provides approximate results.

Why should I care about my package size?

  • Small package is installed much faster on CI
  • Runs faster via npx
  • Less dependencies = less troubles
