How to upload multiple image in NODEJS with MULTER

First of all you have to install multer package in your system and then paste text below typed:


var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, path.resolve('public') + '/images/uploads/')
  },
  filename: function (req, file, cb) {
    cb(null, Date.now() + path.extname(file.originalname))
  }
});


Storage variables contains the destination of file upload and filename is the access to change file name if you want , i am changing the filename with current date.

next it 

var upload = multer({
  dest: path.resolve('public') + '/images/uploads/',
  limits: {
    fileSize: 3 * 1024 * 1024,
    files: 20
  },
  storage: storage,
  rename: function (fieldname, filename) {
    return fieldname+"_"+Date.now();
  },
  onFileUploadStart: function (file) {
    console.log(file.originalname + ' is starting to upload');
  },
  onFileUploadComplete: function (file) {
    console.log(file.originalname + ' uploaded to  ' + file.path);
  }
});


paste this code group and write post api and incude upload varialbe to store image to the destination 
.
like 
;



router.post('/imageUpload', function(req,res,next)
{
upload(req,res,function(err){
/* for single image*/
req.file.filename   // filename is the image name stored in database 

/* for multiple images*/
req.files.filename 
});

});

  }
});

/**

*/
var fileUploader = multer({
  dest: path.resolve('public') + '/images/uploads/',
  limits: {
    fileSize: 3 * 1024 * 1024,
    files: 1
  },
  storage: storage,
