Don't find file when i upload image to server nodejs (use multer)

I have some problems with my server nodejs when i upload a image by multer. https://github.com/expressjs/multer When i go to folder uploads, i don't see my file uploaded!

My code:

app.use(multer(
    {
        dest: path.join(__dirname, 'uploads'),
        inMemory: true,
        includeEmptyFields: true,
        onFileUploadStart: function (file, req, res) {
            console.log('onFileUploadStart');
            console.log(file);
        },
        onFileUploadData: function (file, data, req, res) {
            console.log('onFileUploadData');
            console.log(file);
        },
        onFileUploadComplete: function (file, req, res) {
            console.log('onFileUploadComplete');
            console.log(file);
        },
        limits: {
            fieldNameSize: 999999999,
            fieldSize: 999999999
        },
        onParseStart: function() {
            console.log('Starting to parse request!');
        },
        onParseEnd: function(req, next) {
            console.log('Done parsing!');
            next();
        },
        onError: function(e, next) {
            if (e) {
                console.log(e.stack);
            }
            next();
        }
    }));

And route: (I received file from client)

router.post('/newapi/addimages',function(req,res){
    try{
         // fileName = file.name, file name passed by client. Not used here. We use the name auto-generated by Node
        var file = req.files.file;
        var filePath = file.path;
        var lastIndex = filePath.lastIndexOf("/");
        var tmpFileName = filePath.substr(lastIndex + 1);
        var image = req.body;
        image.fileName = tmpFileName;
        return res.send({ok:'heyyou'});
    }
    catch(err){
        console.log(err);
        return res.send({ok:'heyyou'});
    }
});

My result:

It's because you have the inMemory option set to true. This option makes the image stay in the process memory instead of piping it to the filesystem and is accessible through the req.files.file.buffer.

Change inMemory to false and you'll be good to go.

You don't have to set each option, and for your application you'd be good with most default values.

app.use(multer({ dest: path.join(__dirname, 'uploads') }));
