Im having node application with express which use multer module

in the app.js file I put the following:

var mulStorage = require("./utils/store"),
    var upload = multer({
        storage: mul.storage,
        dest: 'uploads/'
    });
    app.use(upload.single('file'));

The store.js file look like following

var multer = require('multer');

var stor = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, './uploads/')
    },
    filename: function (req, file, cb) {
        var filename = file.originalname;
        var fileExtension = filename.split(".")[1];
        cb(null, Date.now() + "." + fileExtension);
    }
})
module.exports = {
    stor: stor
}

When I run request using postman I got the following error:

Error: ENOENT: no such file or directory, open 'c:\Users\c45669\WebstormProjects\App\uploads\1454935327214.zip'
   at Error (native)

Why multer doesn't create the folder if it doesn't exist??

If I'm creating the upload folder under the root manually this is working...

BTW, When I change the following and remove the storage: mul.storage, This is working, but I need the storage to determine the file name ...

    var upload = multer({
        //storage: mul.storage,
        dest: 'uploads/'
    });

Even If I remove the property dest from multer object and keep only the storage I got the same error...

• javascript
• node.js
• express
• multipart
• multer

• As mentioned in the answer, multer does not create the folder it should be created either manually or programmatically. Assuming that the uploads folder exist, is there any other that you are facing with uploads? – Raf Commented Feb 8, 2016 at 15:16

Why multer doesn't create the folder if it doesn't exist??

This is in documentation (link) :

Note: You are responsible for creating the directory when providing destination as a function. When passing a string, multer will make sure that the directory is created for you.

I don't know why the author made this decision, but as you see this is not a bug.

You can use fs module to create directories.

I had the same problem if someone take the error i solved

var storage = multer.diskStorage({
 destination: function (req, file, cb) {
 cb(null, 'this is not just /uploads do it like /var/www/....') thank you!!
},
filename: function (req, file, cb) {
cb(null, file.fieldname + '-' + Date.now())
}
})
var upload = multer({ storage: storage });
