i read issue of answers found doesn't work me. using passpotjs , local strategy in order make login routine. using express , reactjs well. when try call callback 'auth' module created passport local strategy, strategy never called. here code (the important part):

server

import express 'express'; import bodyparser 'body-parser'; import cookieparser 'cookie-parser'; import passport 'passport'; import react 'react';  import config './config' import routes './pages/containers/routes'; import auth './auth';  var clientapi = lisaclient.createclient(config.lisaclient);  const lisaapp = express();  lisaapp.use(bodyparser.json()) lisaapp.use(bodyparser.urlencoded({ extended: false })) lisaapp.use(cookieparser()) lisaapp.use(expresssession({   secret: config.secret,   resave: false,   saveunitialized: false })) lisaapp.use(passport.initialize()) lisaapp.use(passport.session())  passport.use(auth.localstrategy); // here call strategy 'auth' module passport.deserializeuser(auth.deserializeuser); passport.serializeuser(auth.serializeuser);  lisaapp.post('/login', (req, res) => {   const validationresult = validateloginform(req.body);   if (!validationresult.success) {     return res.status(400).json({       success: false,       message: validationresult.message,       errors: validationresult.errors     });   } // initial form validation ok    return passport.authenticate('local', (err, token, userdata) => {     console.log('response'); //always ok, no matter what. never call 'local'.   })(req, res, next); });   lisaapp.listen(3000, () => {   console.log('lisa listening 3000'); }); 

auth (module)

var localstrategy = require('passport-local').strategy; var lisaclient = require('pos_lisa-client'); var config = require('../config');  var clientapi = lisaclient.createclient(config.lisaclient);  exports.localstrategy = new localstrategy((userclient, password, done) => {   // never enter here, no matter if put console log   console.log('strategy invoked');   clientapi.auth(userclient, password, (err, token) => {     if (err) {       return done(null, false, { message: 'data not found' })     }      clientapi.getclient(userclient, (err, client) => {       if (err) {         return done(null, flase, { message: `an error ocurred: ${err.message}` })       }        client.token = token       return done(null, client)     })   }) })
