Image is overwriting in local Folder using multer in Node.js app

Question

I am trying to upload image in Local folder as well as saving the image name in MongoDB.

var uploadDir=__dirname+'/uploads';
 var images=Date.now()+'.jpg';
var storage=multer.diskStorage({

    destination:function(request, file, callback){
        callback(null, uploadDir);
        },
        filename:function(request, file, callback){
            console.log(file);
            callback(null, images);
            }
    });
    var upload=multer({storage:storage}).single('image');

Above is the multer configuration code. The problem is that while I insert an image then it is saving successfully in local folder but again I save another image then the new image is overwriting the previous image in folder. But in MongoDB images name are differents.

Answer 1

You have added images value as Date.now on top the file which will executes once at the time of loading .

Try below code.

var uploadDir=__dirname+'/uploads';

var storage= multer.diskStorage({

destination:function(request, file, callback){
    callback(null, uploadDir);
    },
    filename:function(request, file, callback){
        var images = '.jpg';
        console.log(file);
        images += Date.now()+images;
        callback(null, images);
        }
});
var upload=multer({storage:storage}).single('image');
