node.js - passportjs validate on signup if user already exists -
i trying create sign user if existing in db logged system, or else new user created in system.
so far have come following code.
//filename passport-config var config = require('./config'); var passport = require('passport'); var user = require('./models/user'); var localstrategy = require('passport-local').strategy; var isvalidpassword = function(user, password){ return bcrypt.comparesync(password, user.password); }; // generates hash using bcrypt var createhash = function(password){ return bcrypt.hashsync(password, bcrypt.gensaltsync(10), null); } // middleware quintessential call next() // if user authenticated var isauthenticated = function (req, res, next) { if (req.isauthenticated()) return next(); res.redirect('/'); } passport.use('signup', new localstrategy({ passreqtocallback : true }, function(req, email, password, done) { findorcreateuser = function(){ // find user in mongo provided email user.findone({'email':email},function(err, user) { // in case of error return if (err){ console.log('error in signup: '+err); return done(err); } // exists if (user) { user.findone({ 'email' : email }, function(err, user) { if (!user){ console.log('user not found email '+email); return done(null, false); } // user exists wrong password, log error if (!isvalidpassword(user, password)){ console.log('invalid password'); return done(null,false); } }); } else { // if there no user email // create user var newuser = new user(); // set user's local credentials newuser.email = email; newuser.password = createhash(password); // save user newuser.save(function(err) { if (err){ console.log('error in saving user: '+err); throw err; } console.log('user registration succesful'); return done(null, newuser); }); } }); }; // delay execution of findorcreateuser , execute // method in next tick of event loop process.nexttick(findorcreateuser); }) ); my router
router.post('/signup', passport.authenticate('signup', { successredirect: '/timeslot', failureredirect: '/' })); server.js file var express = require('express'); var bodyparser = require('body-parser'); var leisure = require('leisure'); var cors = require('cors'); var passport = require('passport'); var config = require('./config'); var passportconfig = require('./passport-config'); var session = require('express-session') var expresshbs = require('express-handlebars'); var mediatypes = [ { contenttype: 'application/hal+json' }, { contenttype: 'application/json' }, { contenttype: 'text/html' } ]; var app = express(); /*handlebars */ app.engine('handlebars', expresshbs({layout: false}) ); app.set('view engine', 'handlebars'); app.use(express.static(__dirname + '/assets')); app.use(cors(config.settings.cors)); app.use(bodyparser()); app.use(leisure.accept(mediatypes)); /*sessions */ app.use(session({ secret: 'keyboardsfs23432@@!#!@at' })); app.use(passport.initialize()); app.use(passport.session()); var routes = require('./routes'); app.use('/', routes.router); function start () { var port = process.env.port || 3000; app.listen(port); console.log('appoints service started on port ' + port); } exports.app = app; exports.start = start; the signup route doesn't work @ , pretty confused on how debug this, suggestions appreciated.
