You need to use app.use(multer({dest:'./uploads/'})) in the form of one of these:
app.use(multer({dest:'./uploads/'}).single(...));
app.use(multer({dest:'./uploads/'}).array(...));
app.use(multer({dest:'./uploads/'}).fields(...));
ie:
app.use(multer({dest:'./uploads/'}).single('photo'));
And be sure to have something like:
<form action="/postPhotos" enctype="multipart/form-data">
<input type="file" name="photo">
<input type="submit" value="Upload photo">
</form>
In your html.

I'm trying to make a simple file upload system but everytime I submit my uploaded file I get a 404 error. I've tried various different names and paths but all of them fail instantly. When I press submit, the browser tries to redirect to /upload then returns the 404 error. I'm new to node.js so it may as well be very simple to solve but I couldn't find it.
I've tried 2 different modules, formidable and express-fileupload. Both return the same error.
./views/test2.ejs
<html>
<head>
</head>
<body>
<form action="/upload" method="post" enctype="multipart/form-data">
<input type="file" name="filetoupload"><br>
<input type="submit">
</form>
</body>

res.render('test2');
res.sendFile(__dirname + '/test2.ejs');
});
router.post('/upload', function (req, res, next) {
var form = new formidable.IncomingForm();
form.parse(req);
form.on('fileBegin', function (name, file) {
file.path = __dirname + '/uploads/' + file.name;

form.on('file', function (name, file) {
console.log('Uploaded ' + file.name);

you used app.use('/test2', test2); for the /upload routing
So form action should be "/test2/upload"
I seem to be having a problem when applying a user to a session. When I login, the function runs perfect and bcrypt check the password perfectly. But when the req.session.user = user is called I get Cannot set property user of undefined.
Here is my users.js file
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');
var expressValidator = require('express-validator');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
router.use(expressValidator);
var UserModel = require('../models/user');
/* GET users listing. */
router.get('/register', function(req, res, next) {
res.send('respond with a resource');
});
router.get('/login', function(req, res, next) {
res.send('respond with a resource');
});
router.registerUser = function(req,res){
console.warn('Getting Here');
var name = req.body.name;
var email = req.body.email;
var username = req.body.username;
var password = req.body.password;
var password2 = req.body.password2;
console.log(req.body.name);
var newUser = new UserModel({
name:name,
email:email,
username:username,
password: password
});
UserModel.createUser(newUser, function(err,user){
if(err) throw err;
console.log(user);
});
}
router.login = function(req,res){
var username = req.body.username;
var password = req.body.password;
UserModel.findById("584340be3f63a303484eccc0", function(err, user){
console.warn(user.username);
console.warn(user.password);
bcrypt.compare(password , user.password, function(err,res) {
if (err) throw err;
});
console.warn (user);
req.session.user = user;
console.warn(req.session.user);
})
}

I've been at this problem for quite a while now and was wondering if anyone can send me in the right direction. Thanks in advance!
I found the issue. In app.js I had some of my app.use functions placed below the app.user('router') and it was causing the issue
I'm trying to get Toastr library to work in my ExpressJS app! I scaffolded the app with the yeoman 'standard' Express Generator...
I've required the lib express-toastr and did the following:
in app.js:
const cookieParser = require('cookie-parser');
const session = require('express-session');
const flash = require('connect-flash');
const toastr = require('express-toastr');
app.use(cookieParser());
app.use(session( {secret: 'xxx', saveUninitialized: true, resave: true} ));
app.use(flash());
app.use(toastr());
in index.js
const express = require('express');
const router = express.Router();
const httpntlm = require('httpntlm');
router.post('/', function (req, res, next) {
// parse inputs
let user = req.body.user || "";
let password = req.body.password || "";
// save in session
req.session.user = {user: user, password: password};
// appropriate response to login attempt
if (!req.session.user) {
res.status(401).send();
}
else {
req.toastr.success('Successfully logged in.', "You're in!");
res.render('groups', {
req: req
});
}
});
module.exports = router;
In index.jade
#{req.toastr.render()}
I'm loading these files in my <head> section:
link(rel='stylesheet', href='//cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.2/css/toastr.min.css')
script(src='/components/jquery/dist/jquery.min.js')

Nothing is showing. What am I missing???

Try using this middleware in your app.js, I found this here
app.use(function (req, res, next)
{
res.locals.toasts = req.toastr.render()
next()
});
and then access locals in your view as follows:
#{toasts}
This worked for me.
So I am not familiar with your syntax in your index.jade file(!=). What does it do? If you change that line in your index to #{req.toastr.render()} it should work.
I am using express and I have a catch all route
router.use('*',function(){...});
and a root route
router.use('/', function(){...});
I have this route placed after the
app.use(express.static(path.join(__dirname, 'public')));
this causes my routes to not fire when placed below the previous line. however if I put my routes above it my catch all is also called on static asset requests. is there a way I can catch all requests except for the assets in my public folder including the route '/'? I don't want to resort to using regex and having to update it every time a directory is added to the public directory.

I'd like to show index page by index.js and index.jade on Node.js, however browser returns the page only show index.html as attached picture.
I set the index.js as routes as following, thus I think the root path should return index page.

app.use('/', sessionCheck, routes);
