How to remove all old files in directory using node js

Question

I have directory with files.

I would like to delete (zip) files which were created before 7days ago.

I would like to run this script every day.

I can get all files in dir using:

  fs.readdirSync('/data/mongodump/').forEach(file => {
    console.log(file);
  });

But I dont know how to compare (get) dates, then I can call unlink .

Can anyone help me?

You can you FS.statsSync() native API where ctime is the last changed time, but you can also use birthtime for creation date.

Documentation:https://nodejs.org/api/fs.html#fs_fs_stat_path_options_callback

fs.readdirSync('/data/mongodump/').forEach(file => {
  const isOlder = fs.statSync(`/data/mongodump/${file}`).ctime < Date.now() - 604800000 // 604800000 = 7 * 24 * 60 * 60 * 1000

  if (isOlder) {
    fs.unlinkSync(`/data/mongodump/${file}`)
  } 

})

Bests,
