You can make a function like so:

var uploadFnct = function(dest){
        var storage = multer.diskStorage({ //multers disk storage settings
            destination: function (req, file, cb) {
                cb(null, './public/img/'+dest+'/');
            },
            filename: function (req, file, cb) {
                var datetimestamp = Date.now();
                cb(null, file.fieldname + '-' + datetimestamp + '.' + file.originalname.split('.')[file.originalname.split('.').length -1]);
            }
        });

        var upload = multer({ //multer settings
                        storage: storage
                    }).single('file');

        return upload;
    };

And then use it in your upload route:

//Handle the library upload
    app.post('/app/library/upload', isAuthenticated, function (req, res) {
        var currUpload = uploadFnct('library');
        currUpload(req,res,function(err){
            if(err){
                 res.json({error_code:1,err_desc:err});
                 return;
            }
            res.json({error_code:0,err_desc:null, filename: req.file.filename});
        });
    });
