Delete several files in node.js

Question

What is the best way to delete several files in node.js?

function deleteFiles(files, callback){
    ...
}

var files = [\'file1.js\', \'file2.jpg\', \'file3.css\         


        

Answer 1

Asynchronous:

var fs = require('fs');

function deleteFiles(files, callback){
  var i = files.length;
  files.forEach(function(filepath){
    fs.unlink(filepath, function(err) {
      i--;
      if (err) {
        callback(err);
        return;
      } else if (i <= 0) {
        callback(null);
      }
    });
  });
}

var files = ['file1.js', 'file2.jpg', 'file3.css'];

deleteFiles(files, function(err) {
  if (err) {
    console.log(err);
  } else {
    console.log('all files removed');
  }
});

Answer 2

This is what I am currently using and works a treat:

var files = ['file1.js', 'file2.jpg', 'file3.css'];
    
    function deleteFiles(files){
        for (const file of files) {
            fs.unlink((file), err => {
                if (err) throw err;
            });
        };
    }

deleteFiles(files);
