express js cannot GET /page - javascript

I am very stuck with a routing error on express.js. I am using jade to render my page views. I have read all the docs and refactored many times to no avail.
This is the plain contents of the link that is pointing to the '/sell' route.
index.jade
include layout
html
button.btn.btn-primary(type='submit', href='/sell') Add Item
When clicking this button the browser returns the following as a 404:
Cannot GET /sell
The problem here is that all other routes work correctly, if you are to modify the above href to other pages i.e. '/' , '/sign_in', etc no error occurs. The problem appears to be isolated to the '/sell' route.
The controller with the '/sell' route is below:

button#btnSubmit.btn.btn-primary(type='submit') Post Item

I think it's acting as form post and tries to reach app.post('/sell')
Change it:
button.btn.btn-primary(type='submit', href='/sell') Add Item
to:
a.btn.btn-primary(href='/sell') Add Item
also remove some parts of middleware and keep only these lines:
app.set('views', 'app/views');
app.set('view engine', 'jade');
app.set('port', process.env.PORT || 3000);
app.use(logger('dev'));
and then navigate in Your browser to /sell route, check if it's working.
if Yes - so problem with one of middlewares that we have deleted to check.

You should add a logger middleware and see what error the server gives when you try to go to that route. Another thing to try would be to rename the sell route and see if that works. That could indicate a conflict with another one of your routes, although it's not clear where this would be from looking at your code.

Passport.JS deserializeUser Is Never Reached

I have tried almost every method known to stack Overflow but my issue is persisting as the days goes by and I'm really hoping for some help here. As you can tell from the title, Passport-local does not call deserializeUser for some odd reason. My files are set up as shown below.

I am totally unsure as to what I did wrong here. One thing I will say is, when I change all app.use() to router.use() in my User.Js, I got a consider upgrading MySQL error when I am using mysql2. Regardless, I don't think mysql is my issue because I am able to register to the DB fine using mysql2 and app.use. I believe my issue most likely lies in the router.post(/login).
I ended up just moving to my own encryption method which uses bcrypt. It was the easiest and securest way to go about this process especially with out wasting to much time. If I ever find the solution in the future, I’ll post it on GitHub and will post the link here.
More information on Bcrypt.

Post route returning nothing

I've been following a guide on implementing a password reset in Node. I'm working on the password reset post route below and when I post nothing seems to happen, it justs reloads the reset page. ive added some console.log() in various places on the code but they dont get executed. Hope someone can assist. ive deleted the other routes to make the code shorter

i figured out the issue, it was to do with my form. I had forgotten to add:
<form method="post" action="/password_reset">
so the form was not sending anything.

Error: Uncaught, unspecified "error" event. (Not a valid BCrypt hash.)

I am trying to create an api for login in nodejs.but when i check the login route via Http requester it showing nothing in output and command line showing error Error: Uncaught, unspecified "error" event. (Not a valid BCrypt hash.) and i find out that password is not stored in database in encrypted/hash form.

Your code calls next() twice in your pre-save function, remove it as followed:
UserSchema.pre('save', function(next) {
var user = this;
bcrypt.hash(user.password, null, null, function(err, hash) {
if (err) return next(err);
user.password = hash;
next();
});
next(); // function to remove
});

NodeJS doesn't like passport + sequelize logins

I'm going crazy with nodejs. I'm trying to realize the backend for a simple user management webapp powered by NodeJS, using Passport-Local and Sequelize libraries. Right now I just designed the user model. The main problem I have is that the signup process gives me an error: it looks like that I'm working on an undefined object. Could please someone help me in figuring out what's going on?
Here is my code (merged with some solutions I found on internet - obviously nothing works, according to Murphy's laws).
Could please Javascript programmers forgive me if the code is not good. My excuse is that it is my first programming attempt in Javascript, I MUST do it for a project and last (excuse) but not least I grew up with C and microchips.

passport.serializeUser(function(user,done) {
done(null, user.id);
});
var generateHash = function(password) {
return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
};
Problem solved.
"Just" changed how to reference the model in passport.js as follow
var User = user;
had to rewritten as
var User = db.user;
Here the definitive passport strategy file
const db = require('./../models/');
var bCrypt = require('bcrypt-nodejs');
module.exports = function(passport) {
var User = db.user;
var LocalStrategy = require('passport-local').Strategy;
passport.use('local-signup', new LocalStrategy(
{
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(req, email, password, done) {
var generateHash = function(password) {
return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
};
User.findOne({
where: {
email: email
}
}).then(function(user) {
if (user) {
return done(null, false, {message: req.flash('email already taken')});
console.log('mail already taken');
}
else {
var pass = generateHash(password);
var data =
{
email: email,
password: pass,
username: req.body.username,
public_key: '0',
last_login: null
};
User.create(data).then(function(newUser, created) {
if (!newUser) {
return done(null, false);
}
if (newUser) {
return done(null, newUser, {message: req.flash('tappost')});
}
});
}
}).catch(function(err) {
console.log(err);
});
}
));
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id).then(function(user){
done(null, user);
}).catch(function(e){
done(e, false);
});
});
}

nodejs passport LogIn

I set-up passport on nodejs with mongoose for allowing users to login and create new accounts. Create new account is working but the login part doesn't.
users.js
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongoose = require('mongoose');
var User = require('../models/user');
router.get('/login', function(req, res, next) {
res.render('login', {
'title': 'Login'
});
});
passport.serializeUser(function(user, done){done(null, user);});
passport.deserializeUser(function(id, done){
User.getUserById(id, function(err, user){
done(err, user);
});
});
passport.use(new LocalStrategy(
function(username, password, done){
User.getUserByUsername(username, function(err, user){
if(err) throw err;
if(!user){
console.log('Unknown User');
return done(null, false,{message: 'Unknown User'});
}
User.comparePassword(password, user.password, function(err, isMatch){
if(err) throw err;
if(isMatch){
return done(null, user);
}else{
console.log('Invalid Password');
return done(null, false, {message: 'Invalid password'});
}
});
});
}
));
router.post('/login', passport.authenticate('local', {successRedirect: '/',failureRedirect: '/users/register', failureFlash:'Invalid username or password'}), function(req,res){
console.log('Authentication Successful');
req.flash('success', 'You are logged in');
res.redirect('/');
});
../models/user.js
var mongoose = require('mongoose');
var bcrypt = require('bcrypt');
mongoose.connect('mongodb://localhost/nodeauth');
var db = mongoose.connection;
var UserSchema = mongoose.Schema({
username: {
type: String,
index: true
},
password: {
type: String, required: true, bcrypt: true
},
email:{
type: String
},
name:{
type: String
},
profileimage:{
type: String
}
});
var User = module.exports = mongoose.model('User', UserSchema);
module.exports.comparePassword = function(candidatePassword, hash, callback){
bcrypt.compare(candidatePassword, hash, function(err, isMatch){
if(err) return callback(err);
callback(null,isMatch);
});
}
module.exports.getUserById = function(id, callback){
User.findById(id, callback);
}
module.exports.getUserByUsername = function(username, callback){
var query = {username: username};
User.findOne(query, callback);
}
module.exports.createUser = function(newUser, callback){
bcrypt.hash(newUser.password, 10, function(err, hash){
if(err) throw err;
// Set hashed pw
newUser.password = hash;
// Create User
newUser.save(callback);
});
}
If I create the new user than is working the data are uploading the MongoDB but if I try to Log In it just drop me to the /users/register page I do not have any error
Well it is not doing anything because your login route is not calling anything... check the documentation on http://passportjs.org/docs to see how passport works.
In user.js you need something like
router.get('/login',
passport.authenticate('local'),
function(req, res) {
res.render('login', {
'title': 'Login'
});
});
Then in a separate file you need to setup your authentication strategy, for example:
var passport = require('passport')
, LocalStrategy = require('passport-local').Strategy;
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({ username: username }, function (err, user) {
if (err) { return done(err); }
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
}
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' });
}
return done(null, user);
});
}
));
Check this tutorial for a step-by-step on implementing local authentication strategy.

If you want something more advanced, this code has examples of social authentication strategies (for example, your users can log in using Facebook accounts)

Good luck!
