A Node.js script to remove all files in a directory recursively

recursiveRemoveFiles.js

var fs = require('fs')
  , path = require('path')
  , _ = require('underscore');

var rootPath = "/path/to/remove";
removeDirForce(rootPath);

// path should have trailing slash
function removeDirForce(dirPath) {
  fs.readdir(dirPath, function(err, files) {
    if (err) {
      console.log(JSON.stringify(err));
    } else {
      if (files.length === 0) {
	fs.rmdir(dirPath, function(err) {
	  if (err) {
            console.log(JSON.stringify(err));
	  } else {
	    var parentPath = path.normalize(dirPath + '/..') + '/';
	    if (parentPath != path.normalize(rootPath)) {
	      removeDirForce(parentPath);
	    }
	  }
	});
      } else {
	_.each(files, function(file) {
	  var filePath = dirPath + file;
	  fs.stat(filePath, function(err, stats) {
	    if (err) {
	      console.log(JSON.stringify(err));
	    } else {
	      if (stats.isFile()) {
		fs.unlink(filePath, function(err) {
		  if (err) {
                    console.log(JSON.stringify(err));
		  }
		});
	      }

	      if (stats.isDirectory()) {
		removeDirForce(filePath + '/');
	      }
	    }
	  });
	});
      }
    }
  });
}

@iserdmi Thanks. I needed a version that wouldn't delete the directory itself.

Maybe it will be usefull for someone. Extend @guybedfrod function, to remove all in dir but not dir itself.

    rmDir = function(dirPath, removeSelf) {
      if (removeSelf === undefined)
        removeSelf = true;
      try { var files = fs.readdirSync(dirPath); }
      catch(e) { return; }
      if (files.length > 0)
        for (var i = 0; i < files.length; i++) {
          var filePath = dirPath + '/' + files[i];
          if (fs.statSync(filePath).isFile())
            fs.unlinkSync(filePath);
          else
            rmDir(filePath);
        }
      if (removeSelf)
        fs.rmdirSync(dirPath);
    };

Call rmDir('path/to/dir') to remove all inside dir and dir itself. Call rmDir('path/to/dir', false) to remove all inside, but not dir itself.

This is helpful. Thanks!
