Node.JS doesn't automatically save uploaded files to disk. You'll instead have to read and parse the multipart/form-data content yourself via the request's data and end events.

Or, you can use a library to do that all for you, such as connect/express for its bodyParser or multipart middlewares (complete example):

var fs = require('fs');
var express = require('express');
var app = express();

// `bodyParser` includes `multipart`
app.use(express.bodyParser());

app.post('/', function(req, res, next){
  // assuming <input type="file" name="upload">

  var path = req.files.upload.path;
  var name = req.files.upload.name;

  // copy...
});

Or use formidable directly, which connect uses for the multipart middleware (complete example).

And, for the // copy... comment, see How to copy a file?.

  • I'm confused...everywhere else says 'multipart' is not in bodyParser, but here it says yes? – newman Sep 20 '15 at 17:53
  • @miliu I just haven't updated this answer. At the time this was posted (3 years ago), support for `multipart` was included with the `bodyParser` middleware but has since been removed in favor of other modules dedicated to handling the format, such as [`multer`](https://www.npmjs.org/package/multer) ([mentioned in Express' docs](http://expressjs.com/4x/api.html#req.body)). Another significant change since this post is that Express no longer depends upon Connect. – Jonathan Lonowski Sep 20 '15 at 17:56

app.post('/', function(req, res, next){
    var file_name=req.file.filename;
    var file_path=req.file.path;
}

    While this code may answer the question, providing additional context regarding *why* and/or *how* this code answers the question improves its long-term value. – Tân Nov 30 '19 at 12:30
