I am trying to write a function that will remove files in a directory that are more than 1 day old. Currently, my logic is as follows:
ctime
and the file's ctime
is greater than 1 day My code to accomplish the above is below:
var fs = require('fs');
var path = require('path');
var uploadsDir = __dirname + '/uploaded_files'
fs.readdir(uploadsDir, function(err, files) {
var removedFiles = [];
files.forEach(function(file, index) {
filePath = path.join(uploadsDir, file);
console.log(filePath);
fs.stat(filePath, function(err, stat) {
if (err) {
return console.error(err);
}
var now = new Date();
var endTime = new Date(stat.ctime);
var diffDays = parseInt((now - endTime) / (1000 * 60 * 60 * 24))
console.log(now);
console.log(endTime);
console.log(diffDays + ' days');
if (diffDays >= 1) {
fs.unlink(filePath, function(err) {
if (err) {
return console.log(err);
}
});
removedFiles.push(file)
console.log(filePath + ' has been removed!');
console.log(file);
console.log('\n');
}
}); // end of fs.stat
}); // end of forEach
});
So far, my code has been successful only in removing the last file in the array someotherfile.png
. Then it starts complaining like this:
/Users/username/api/uploaded_files/.DS_Store
/Users/username/api/uploaded_files/anotherfile.png
/Users/username/api/uploaded_files/somefile.png
/Users/username/api/uploaded_files/someotherfile.png

Could someone please tell me what is wrong?
It turns out I missed declaring my filePath
as a variable. Thanks to @CertainPerformance.
var fs = require('fs');
var path = require('path');
var uploadsDir = __dirname + '/uploaded_files'
fs.readdir(uploadsDir, function(err, files) {
var removedFiles = [];
files.forEach(function(file, index) {
var filePath = path.join(uploadsDir, file); //added this var here and it works now!
console.log(filePath);
