javascript - Using multer cause error when running app -


im having node application express use multer module https://github.com/expressjs/multer

in app.js file put following: 

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

the store.js file 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 run request using postman got 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 folder if doesn't exist??

if i'm creating upload folder under root manually working...

btw, when change following , remove storage: mul.storage, working, need storage determine file name ...

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

even if remove property dest multer object , keep storage got same error...

why multer doesn't create folder if doesn't exist??

this in documentation (link) :

note: responsible creating directory when providing destination function. when passing string, multer make sure directory created you.

i don't know why author made decision, see not bug.

you can use fs module create directories.
