count-files

Count files, directories, and bytes in a directory recursively.
Ignore files in the count.

Usage

In javascript, use it like so:

var countFiles = require('count-files')

var stats = countFiles(dir, function (err, results) {
  console.log('done counting')
  console.log(results) // { files: 10, dirs: 2, bytes: 234 }
})

setInterval(function () {
  console.log('current count', stats) // { files: 4, dirs: 1, bytes: 34 }
}, 500)

count-files also has a very simple command line tool, use npm install -g count-files to install.

❯ count-files ./
Counting files and directories in...
/joe/node_modules/count-files

Results:
 Files:  13
 Dirs:   4
 Size:   10 KB

API

var stats = countFiles(src, opts, cb) { }

src can be a directory or a single file path. You can also pass a custom fs, e.g. hyperdrive and path with: {fs: customFs, name: dir} (see tests for examples).
Callback returns the completed stats: {files, dirs, bytes}.
Options include:

opts = {
  ignore: function (file) {
    return match(['**/*.js'], file) // return true to ignore file
  }
  dereference: false // dereference any symlinks
}

We find anymatch nice for ignoring files!
That's all folks!

Development

• Run tests! npm test
• Run performance thingy! npm run perf
• Yay!

Some basic performance testing in tests/perf.js and alternate implementations in lib/. I think I chose the fastest but didn't test all situations!
