User coming as null while authenticating with passport js - node.js

Question

I am new to Node/mongodb/passport, trying to authenticate using passport.
here is my auth.js
var User = require('../models/userModel'),
passport = require('passport'),
BasicStrategy = require('passport-http').BasicStrategy,
jwt = require('jsonwebtoken');
passport.use(new BasicStrategy(function(userid, password, done){
User.findOne({ 'userid': userid }, function(err, user){
if(err){
return done(err);
}
if(!user){
return done(null, false);
}
if(!user.verifyPassword(password)){
return done(null, false);
}
return done(null, user);
})
}));
exports.generateToken = function(req, res, next){
req.token = jwt.sign({ id:req.user.userid },'secret key', { expiresInMinutes:120 });
next();
};
exports.respond = function(req, res){
req.status(200).json({
user: req.user,
token:req.token
});
};
exports.isAuthenticated = passport.authenticate('basic', {session:false});
For database, I simply created a user to test in the following way:
db.UserSchema.insert({"userid": "hm", "password":"mm123"})
here is my userModel.js
var mongoose = require('mongoose'),
bcrypt = require('bcrypt-nodejs');
var UserSchema = new mongoose.Schema({
userid: {
type: String,
unique: true,
required: true
},
password: {
type: String,
required: true
},
access_token: String
});
UserSchema.methods.verifyPassword = function(password, cb) {
bcrypt.compare(password, this.password, function(err, isMatch) {
if (err) return cb(err);
cb(null, isMatch);
});
};
module.exports = mongoose.model('User', UserSchema);
when I send a request using postman and debug using node-inspector, user come as null in auth.js and in console
Runtime.getProperties failed.
Error: No scopes
here is the server.js
var express = require('express'),
mongoose = require('mongoose'),
bodyParser = require('body-parser'),
path = require('path'),
passport =require('passport'),
authentication = require('./auth/auth');
var db;
if (process.env.ENV == 'Test') {
db = mongoose.connect('mongodb://localhost/fxtest');
}else{
db = mongoose.connect('mongodb://localhost/fx');
}
var app = express();
var port = process.env.PORT || 3000;
app.listen(port, function(){
console.log('Running on Port using gulp:', port);
});
app.use(passport.initialize());
app.post('/auth',authentication.isAuthenticated,
authentication.generateToken, authentication.respond);
module.exports = app;
Can anyone give me any leads as to what am I missing here??

Answer 1

You're responding with the request object which you can't do. You need to respond on the response object.
Its also worth pointing out, that unless you have a cleanup procedure that needs to happen after you respond, you should use a return with your res object.
exports.respond = function(req, res){
// This is wrong
req.status(200).json({
user: req.user,
token:req.token
});
// This is correct
return res.status(200).json({
user: req.user,
token: req.token,
});
};

I got it resolved. The problem was I had given the collection name as UserSchema, whereas my model name was User. As stated in mongoose docs here:
Mongoose automatically looks for the plural version of your model
name
and so it was looking for users as a collection.
