I am trying to upload a file to my node js server using express. Here is my nodejs code:
var express=require('express');
var app=express();
var fs=require('fs');
var sys=require('sys');
app.listen(8080);
app.get('/',function(req,res){
fs.readFile('upload.html',function (err, data){
res.writeHead(200, {'Content-Type': 'text/html','Content-Length':data.length});
res.write(data);
res.end();
});
});
app.post('/upload',function(req,res)
{
console.log(req.files);
fs.readFile(req.files.displayImage.path, function (err, data) {
// ...
var newPath = __dirname;
fs.writeFile(newPath, data, function (err) {
res.redirect("back");
});
});
});
My upload.html file:
<html>
<head>
<title>Upload Example</title>
</head>
<body>
<form id="uploadForm"
enctype="multipart/form-data"
action="/upload"
method="post">
<input type="file" id="userPhotoInput" name="displayImage" />
<input type="submit" value="Submit">
</form>
<span id="status" />
<img id="uploadedImage" />
</body>
</html>
I am getting an error that the req.files is undefined. What could be wrong? The file upload is also not working.

As noted in the docs, req.files, along with req.body are provided by the bodyParser middleware. You can add the middleware like this:
app.use(express.bodyParser());
// or, as `req.files` is only provided by the multipart middleware, you could
// add just that if you're not concerned with parsing non-multipart uploads,
// like:
app.use(express.multipart());
