Created Date of a File

Use the fs module in Node.js to retrieve a stats instance of a given file including meta data like the creation date, last modified dates, accessed dates, and more.

The file’s created date is the birthtime property in the stats object:

const Fs = require('fs')

function createdDate (file) {  
  const { birthtime } = Fs.statSync(file)

  return birthtime
}

console.log(  
  createdDate('./file.txt')
)
// -> 2018-12-28T10:29:43.879Z

The birthtime is a JavaScript Date instance with all the date-related methods and properties.

Notice that there’s a birthtimeMs property in the stats object holding the file’s created date in milliseconds.

Enjoy coding & make it rock!
