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!
