I'm using node v0.10.26 and express v4.2.0 and I'm pretty new to node. I've been beating my head against my desk for the past three or so hours trying to get a file upload form working with node. At this point I'm just trying to get req.files to not return undefined. My view looks like this
<!DOCTYPE html>
<html>
<head>
<title>{{ title }}</title>
<link rel='stylesheet' href='/stylesheets/style.css' />
</head>
<body>
<h1>{{ title }}</h1>
<p>Welcome to {{ title }}</p>
<form method='post' action='upload' enctype="multipart/form-data">
<input type='file' name='fileUploaded'>
<input type='submit'>
</form>
</body>
</html>
Here are my routes
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});
router.post('/upload', function(req, res){
console.log(req.files);
});
module.exports = router;
And here's my app.js
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');
app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
/// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
I saw somewhere that including methodOverride()
and bodyParser({keepExtensions:true,uploadDir:path})
was supposed to help but I can't even launch my server if I add those lines.
ExpressJS Issue:
Most of the middleware is removed from express 4. check out: http://www.github.com/senchalabs/connect#middleware For multipart middleware like busboy, busboy-connect, formidable, flow, parted is needed.
This example works using connect-busboy middleware.
create /img and /public folders.
Use the folder structure:
\server.js
\img\"where stuff is uploaded to"
\public\index.html
SERVER.JS
var express = require('express'); //Express Web Server
var busboy = require('connect-busboy'); //middleware for form/file upload
var path = require('path'); //used for file path
var fs = require('fs-extra'); //File System - for file manipulation
var app = express();
app.use(busboy());
app.use(express.static(path.join(__dirname, 'public')));
/* ==========================================================
Create a Route (/upload) to handle the Form submission
(handle POST requests to /upload)
Express v4 Route definition
============================================================ */
app.route('/upload')
.post(function (req, res, next) {
var fstream;
req.pipe(req.busboy);
req.busboy.on('file', function (fieldname, file, filename) {
console.log("Uploading: " + filename);
//Path where image will be uploaded
fstream = fs.createWriteStream(__dirname + '/img/' + filename);
file.pipe(fstream);
fstream.on('close', function () {
console.log("Upload Finished of " + filename);
res.redirect('back'); //where to go next
});
});
});
var server = app.listen(3030, function() {
console.log('Listening on port %d', server.address().port);
});
INDEX.HTML
<!DOCTYPE html>
<html lang="en" ng-app="APP">
<head>
<meta charset="UTF-8">
<title>angular file upload</title>
</head>
<body>
<form method='post' action='upload' enctype="multipart/form-data">

</html>
The following will work with formidable SERVER.JS
var express = require('express'); //Express Web Server
var bodyParser = require('body-parser'); //connects bodyParsing middleware
var formidable = require('formidable');
var path = require('path'); //used for file path
var fs =require('fs-extra'); //File System-needed for renaming file etc
var app = express();
app.use(express.static(path.join(__dirname, 'public')));
/* ==========================================================
bodyParser() required to allow Express to see the uploaded files
============================================================ */
app.use(bodyParser({defer: true}));
app.route('/upload')
.post(function (req, res, next) {
var form = new formidable.IncomingForm();
//Formidable uploads to operating systems tmp dir by default
form.uploadDir = "./img"; //set upload directory
form.keepExtensions = true; //keep file extension
form.parse(req, function(err, fields, files) {
res.writeHead(200, {'content-type': 'text/plain'});
res.write('received upload:\n\n');
console.log("form.bytesReceived");
//TESTING
console.log("file size: "+JSON.stringify(files.fileUploaded.size));
console.log("file path: "+JSON.stringify(files.fileUploaded.path));
console.log("file name: "+JSON.stringify(files.fileUploaded.name));
console.log("file type: "+JSON.stringify(files.fileUploaded.type));
console.log("astModifiedDate: "+JSON.stringify(files.fileUploaded.lastModifiedDate));
//Formidable changes the name of the uploaded file
//Rename the file to its original name
fs.rename(files.fileUploaded.path, './img/'+files.fileUploaded.name, function(err) {
if (err)
throw err;
console.log('renamed complete');
});
res.end();
});
});
var server = app.listen(3030, function() {
console.log('Listening on port %d', server.address().port);
});
