select-random-file v1.2.4

select-random-file

Select a random file from a provided directory:

const randomFile = require('select-random-file')

const dir = '/tmp/whatever'
randomFile(dir, (err, file) => {
  console.log(`The random file is: ${file}.`)
})

There are a couple of things that could be added:

• filter files by an extension
• recursively traverse a deeper directory structure
