How do i create two directory at same time using nodejs

Question

I am using this npm to create directory

var mkdirp = require('mkdirp');
var dest = denotes the path
mkdirp(dest, function (err) {
    if (err) cb(err, dest);
    else cb(null, dest);
});

My doubt is how do I create two directory in different path?

I have tried following code:

var dest = first path;
var dest2 = second path;
mkdirp(dest,dest2, function (err) {
  if (err) cb(err, dest);
  else cb(null, dest);
});

But its not working how do I do that?Also, I need to rename for those folder which is in different path at same time.

Updated

var mkdirp = require('mkdirp');
var destArray = [ './root/dest1', './dest2' ]
destArray.map( path => {
  mkdirp(path, function (err) {
    if (err) console.error(err)
    else {
    res.json("ok")
      }
  });
})

I have used this solution, Because of loop am getting can't set headers again

The documentations says usage: mkdirp [DIR1,DIR2..] {OPTIONS}. Try mkdirp( [dest, dest2] , err => ...) — Jeremy Thille

No its throwing error like path must be a string [ './public/uploads/docs/Vishnu T', './public/uploads/inspection/Vishnu T' ] — Vishnu

Show real code var dest = first path; is not real code for instance — Mark Schultheiss

you can try this

var mkdirp = require('mkdirp');
var destArray = [ './root/dest1', './dest2' ]
destArray.forEach( path => {
  mkdirp(path, function (err) {
    if (err) console.error(err)
    else console.log('Directory created: ' + path )
  });
})

Thank you for your reply. Actually am sending json data..So When i am going to create a next path am getting can't set headers error

Why .map? It should be forEach

GansPotter Over a year ago

@JeremyThille Yes, we can use forEach as well

Jeremy Thille Over a year ago

Well in this case, you should use .forEach and not .map because .map is supposed to apply a function to each element in the array and return it, creating a new array, which .forEach does not.

You can do this using the following code

const fs = require('fs');
const {promisify} = require('util');
const mkdir = promisify(fs.mkdir);

const destArray = [ 'dest1', 'dest2'];

Promise.all(destArray.map(destPath => mkdir(destPath))).
   then(res => {
       console.log('Directories created');
   }).
   catch(err => {
       console.error(err);
});
