node.js / expressjs simple file upload issue

I'm working on creating a simple file uploader on a node server with expressjs as the middleware. So far, the server side looks like:

app.post('/upload', function(req, res) {
    console.log(req.files);

    //Handle the file
    fs.readFile(req.files.imageUploader.path, function(err, data) {
        var newPath = __dirname;
        console.log(newPath);
        console.log(data);
        fs.writeFile(newPath, data, function(err) {
            console.log(err);
            res.send("AOK");
        });
    });
});

Now, the log statement for __dirname is my source directory, as expected (C:\Development\GitHub\ExpressFileUpload), however an error is happening on the upload:

{ [Error: EISDIR, open 'C:\Development\GitHub\ExpressFileUpload']
errno: 28,
code: 'EISDIR',
path: 'C:\\Development\\GitHub\\ExpressFileUpload' }

I've tried changing the newPath to be / and ./ but no change, different errors, but still errors. Is it something to do with the double \\ in the path in the error? Am I missing something simple here? Thanks for the help, let me know if more info is needed.

The __dirname global object is a directory, not a file. Therefore, you can't open it for writing, which is what fs.writeFile() attempts to do in your script, hence the reason you are getting a EISDIR. Assuming you want the file to be written with the same name it was uploaded with, you can do this:

var file = req.files.imageUploader;
fs.readFile(file.path, function(err, data) {
  var path = __dirname + '/' + file.name;
  fs.writeFile(path, data, function(err) {
  });
});
