The error says is in: node_modules\express\lib\router\index.js:139:34)
I tried with all and i cannot solve this, i asked many persons but no ones give me a answer that can solve my question.
Like i said this is for a Discord Bot Dashboard

isAuthenticated() in Passport js always return false

I have been browsing the forum but I am unable to find the error in my code , it always results in false and I am not able to solve it , Please help me...
Is there any other way to authenticate user instead of passport so that I can use it.I am adding more sentences as it is not allowing me to post my query,Sorry..

I have used passport and jwt library, to authenticate and maintain session for the user. There is no need to maintain user session on server side.

When index.js file has been executed successfully and listening to a port 3000, then use this URL http://localhost:3000/user/login for authentication, it will accept your username and password, then authenticate using passport and send a token to the client as response. The token can contain user data in encrypted form and have expiry time.

You need the express-session module.
server.js
// Require a possible config.js file with your configuration variables
const Config = require('./models/config.js');
// If the config module is formed as a class
const config = new Config();
const express = new('express');
const app = express();
const session = require('express-session');
const MongoStore = require('connect-mongo')(session);
const uuid = require('uuid/v4');
const mongoose = require('mongoose');
// Require your custom passport local strategy file
const passport = require('./models/sessions');
mongoose.connect('mongodb://localhost:27017/your_db_name', {
useNewUrlParser: true
});
// Set the session options
app.use(session({
// Use UUIDs for session IDs
genid: (req) => {
return uuid()
},
// If you want to store the session in MongoDB using mongoose
// Require your personal mon
store: new MongoStore({
mongooseConnection: mongoose.connection
}),
// Define the session secret in env variable or in config file
secret: process.env.SESSION_SECRET || config.sessionSecretKey,
resave: false,
saveUninitialized: true
}));
// Initialize the passport module
app.use(passport.initialize());
// Tell to passport to use session
app.use(passport.session());
./models/session.js
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const bcrypt = require('bcrypt-nodejs');
// Your custom MongoDB connection module
const db = require('./db');
// Configure passport.js to use the local strategy
passport.use(new LocalStrategy({
usernameField: 'username'
},
(username, password, done) => {
db.User.find({
username: username // But it could use email as well
}).then(res => {
const user = JSON.parse(JSON.stringify(res[0]));
if (!user) {
return done(null, false, {
message: 'Invalid credentials.\n'
});
}
if (!bcrypt.compareSync(password, user.password)) {
return done(null, false, {
message: 'Invalid credentials.\n'
});
}
return done(null, user);
}).catch(error => done(error));
}
));
// Tell passport how to serialize the user
passport.serializeUser((user, done) => {
done(null, user._id);
});
// Tell passport how to deserialize the user
passport.deserializeUser((id, done) => {
db.User.find({
_id: id
}).then(res => {
const response = typeof res !== undefined && res.length != 0 ? JSON.parse(JSON.stringify(res[0])) : null;
done(null, response)
}).catch(error => done(error, false))
});
// Export passport for external usage
module.exports = passport;
./models/db.js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const uuid = require('uuid/v4');
// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/your_db_name', {
useNewUrlParser: true
});
// Define the models container
let models = {};
// Prepare your user schema
const userSchema = Schema({
username: {
type: String,

},
password: {
type: String,
required: true
}
});
// Assign the user schema
models.User = mongoose.model('User', userSchema);
// Export for external usage
module.exports = models;
/*
In that way you can wrap in "models" all schemas:
const newSchema = Schema({
name: String
});
models.Newschema = mongoose.model('Newschema', newSchema);
module.exports = models;
And use it externally like:
const db = require('./models/db');
db.User.find({}).then(docs => {}).catch(err => {});
db.Newschema.find({}).then(docs => {}).catch(err => {});
Etc....
*/
./models/config.js
class Config {
constructor() {
this.sessionSecretKey = "my-awesome-secretkey";
/* And other configurations */
}
}
module.exports = Config;
/*
Externally use like:
const Config = require('./models/config');
const config = new Config();
let sessionSecretKey = config.sessionSecretKey;
*/
Then you can use the req.isAuthenticated() after the login:
// POST the username and password to '/login' router
app.post('/login', (req, res, next) => {
passport.authenticate('local', (err, user, info) => {
if (info) {
return res.send(info.message)
}
if (err) {
return next(err);
}
if (!user) {
return res.sendStatus(404); // Is a shortcut
// OR -> res.status(404).end();
// OR -> res.status(404).send('Not found'); as you like
}
req.login(user, (err) => {
if (err) return next(err);
// Store the user object retrieved from MongoDB in `req.session`
req.session.user = user;
return res.sendStatus(200); // Is a shortcut
// OR -> res.status(200).end();
// OR -> res.status(200).send('OK'); as you like
})
})(req, res, next);
});
// The logout logic
app.get('/logout', verifySession, function (req, res) {
req.session.destroy(function (err) {
req.logout();
res.redirect('/');
});
});
// Verify the session to protect private routers
function verifySession(req, res, next) {
if (req.isAuthenticated()) {
next();
} else {
// Forbidden
res.redirect('/');
// OR -> res.sendStatus(403);
// OR -> res.status(403).end();
// OR -> res.status(403).send('Forbidden'); as you like
}
}
Of course you have to run npm install with all the dependencies required defined in package.json file or manually instal with npm i express-session#latest --s for all the dependencies required: npm i module-name#latest --s.
Don't forget the
const server = app.listen(config.port || 3000, () => {
console.log(`Server running on ${server.address().port} port.`);
});
At the end of server.js file. I hope that it will be useful for you.

When I make a GET request to NodeJS it doesn't run the code in the route

I am trying to make a get request with ajax, it doesn't seem to run the code in my NodeJS /tools route, maybe someone can enlighten me. I am looking to run a script from nodeJS from an AJAX request. xhr GET request doesn't seem to work with to initiate the that console log in the nodejs route.
These are my routes.

This is my html/pug calling the route
section(id="digToolWrapper")
form( id="digToolInput" )
ul
li #[input(id="digTool" name="domain" type="text" placeholder="Can you dig it?")]#[input(id="whois" value="whois" type="button" onclick="digIt()")]
This is my ajax request
function digIt() {
var xhr = new XMLHttpRequest();
var domain = document.getElementById("digTool").value;
xhr.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(domain);
}
};
xhr.open('GET', '/tools', true);
console.log(domain);
xhr.send();
};

Why is my Express api register route not POSTing?

I am trying to make a small authentication system for a practice project I have. I am trying to send POST requests via postman to my express server(http://localhost:4000/api/register), and it's replying back "404 not found" I am following the tutorial here.
Here is my server.js:
const newpost = require('./routes/newpost');
const getposts = require('./routes/getposts');
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const deleteposts = require('./routes/delete');
const editposts = require('./routes/editposts');
const path = require('path');
const app = express();
const webpack = require('webpack');
const webpackConfig = require('../webpack.config');
const webpackMiddleware = require('webpack-dev-middleware');
const webpackHotMiddleware = require('webpack-hot-middleware');
const passport = require('passport');
const port = 4000;
const compiler = webpack(webpackConfig);
const config = require('./config/main');
const mongoose = require('mongoose');
const authRouter = require('./routes/authrouter');
const logger = require('morgan');
// db connection
mongoose.connect(config.database);
app.use(passport.initialize());
/*
app.use(webpackMiddleware(compiler, {
noInfo: true, publicPath: webpackConfig.output.publicPath,
}));
app.use(webpackHotMiddleware(compiler, {
log: console.log,
}));
*/
app.use(cors());
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }));
// parse application/json
app.use(bodyParser.json());
app.use(logger('dev'));
app.use('/newpost', newpost);
app.use('/posts', getposts);
app.use('/delete', deleteposts);
app.use('/edit', editposts);
//auth router to handle auth routes
authRouter(app);
/*
app.get('/*', (req, res) => {
res.sendFile(path.join(__dirname, '../public/index.html'));
}); */
app.listen(port, () => {
console.log(`Listening on port ${port}`);
});
Here is my authrouter.js. These are the routes I'm exporting into my server.js. :
const AuthenticationController = require('../controllers/authentication');
const express = require('express');
// const passportService = require('../config/passport');
/* eslint-disable */
const passport = require('passport');
// Middleware to require login/auth
// const requireAuth = passport.authenticate('jwt', { session: false });
const requireLogin = passport.authenticate('local', { session: false });
module.exports = function(app){
"use-strict";
// init route groups
const apiRoutes = express.Router();
const authRoutes = express.Router();
// auth routes
// set auth routes as subgroup/middleware to apiRoutes
apiRoutes.use('/auth', authRoutes);
// Registration routes
authRoutes.post('/register', AuthenticationController.register);
// Login route
authRoutes.post('/login', requireLogin, AuthenticationController.login);
// Set url for API group routes
app.use('/api', apiRoutes);
};
Here is my authentication.js
const jwt = require('jsonwebtoken');
// const crypto = require('crypto'); used for pw resets
const User = require('../models/user');
const config = require('../config/main');
function generateToken(user) {
return jwt.sign(user, config.secret, {
expiresIn: 10080, // in seconds
});
}
// set user info from request
function setUserInfo(request) {
return {
_id: request._id,
email: request.email,
role: request.role,
};
}
// Login Route
exports.login = function (req, res, next) {
const userInfo = setUserInfo(req.user);
res.status(200).json({
token: `JWT${generateToken(userInfo)}`,
user: userinfo,
});
};
// registration route
exports.register = function (req, res, next) {
// check for registration errors
const email = req.body.email;
const password = req.body.password;
// Return error if no email provided
if (!email) {
return res.status(422).send({ error: 'You must enter an email address' });
}
// Return error if no pw provided
if (!password) {
return res.status(422).send({ error: 'You must enter a password' });
}
User.findOne({ email }, (err, existingUser) => {
if (err) { return next(err); }
// if user is not unique, return error
if (existingUser) {
return res.status(422).send({ error: 'That email address is already in use' });
}
// if email is unique and pw was provided, create acct
const user = new User({
email,
password,
});
user.save((err, user) => {
if (err) { return next(err); }
// Subscribe member to Mailchimp list
// mailchimp.subscribeToNewsLetter(user.email);
// Respond with JWT if user was created
const userInfo = setUserInfo(user);
res.status(201).json({
token: `JWT ${generateToken(userInfo)}`,
user: userInfo,
});
});
});
};
// Role authorization check
exports.roleAuthorization = function (role) {
return function (req, res, next) {
const user = req.user;
User.findById(user._id, (err, foundUser) => {
if (err) {
res.status(422).json({ error: 'No user was found' });
return next(err);
}
// if user is found, check role
if (foundUser.role == role) {
return next();
}
res.status(401).json({ error: 'You are not authorized to view this content ' });
return next('Unauthorized');
});
};
};
Here is my passport.js :
// Importing Passport; strategies; and config
const passport = require('passport');
const User = require('../models/user');
const config = require('./main');
const JwtStrategy = require('passport-jwt').Strategy;
const ExtractJwt = require('passport-jwt').ExtractJwt;
const LocalStrategy = require('passport-local');
const localOptions = { usernameField: 'email' };
// setting up the local Strategy
const localLogin = new LocalStrategy(localOptions, ((email, password, done) => {
User.findOne({ email }, (err, user) => {
if (err) { return done(err); }
if (!user) {
return done(null, false, { error: 'Your login details could not be verified. Please try again.',
});
}
user.comparePassword(password, (err, isMatch) => {
if (err) { return done(err); }
if (!isMatch) {
return done(null, false, { error: 'Your login details could not be verified. Please try again.',
});
}
return done(null, user);
});
});
}));
const jwtOptions = {
// Telling passport to check auth headers for JWT
jwtFromRequest: ExtractJwt.fromAuthHeader(),
// Telling passport where to find the secret
secretOrKey: config.secret,
};
// setting up JWT login strategy
const jwtLogin = new JwtStrategy(jwtOptions, ((payload, done) => {
User.findById(payload._id, (err, user) => {
if (err) { return done(err, false); }
if (user) {
done(null, user);
} else {
done(null, false);
}
});
}));
// allow passport to use the strategies we defined
passport.use(jwtLogin);
passport.use(localLogin);

I believe the correct post endpoint would be api/auth/register
