Passport local strategy is never get called - express

Question

I know this question was asked many times in stack over flow. I tried every accepted answers but can't my local strategy into function. Here is my code
var express = require('express');
var app = express();
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
app.use(cookieParser()); // read cookies (needed for auth)
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));
app.set('trust proxy', 1); // trust first proxy
app.use(session({
secret: '564sdf4as564f56a7s765s4afjkgadxjkbadksj',
resave: true,
saveUninitialized: true,
cookie: { secure: true }
}));
app.use(passport.initialize());
app.use(passport.session());
passport.use(new LocalStrategy({
usernameField:'userName',
passwordField:'password',
passReqToCallback : true
},function(request, userName, password, done) {
console.log(request);
UserAccount.findOne({'userName': userName} , function(err, user) {
if (err) return done(err);
if (!user) return done(null, false, 'Incorrect username.' );
user.verifyPassword(password, function(err, isMatch) {
if (isMatch) {
return done(null, user);
} else {
return done(null, false, 'Incorrect password.');
}
});
});
}));
passport.serializeUser(function(user, done) {
console.log('Serialize user called');
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
console.log('Deserialize user called');
UserAccount.findById(id, function(err, user) {
done(err, user);
});
});
Then I created a router like
var router = express.Router();
require('./controllers/user')(router,passport);
app.use('/api',router);
Then in my user controller I created signIn function like
app.post('/signIn',function (request,response,next){
var variables = request.body;
console.log(variables);
passport.authenticate('local', function(error, user, info) {
console.log(user);
if (error) { console.log(error); return next(err); }
if (!user) { return response.redirect('/login'); }
response.logIn(user, function(err) {
if (err) { return next(err); }
return response.redirect('/users/' + user.username);
});
})(request, response, next);
});
Then I send a request from "Postman"
{
"userName":"karthik#abc.com",
"password":"qwerty"
}
My mongodb userName and password fields are same.
In my db there is an account with this user name and password. But every time it return 'user' as 'false' inside authenticate. I tried to console my request inside local strategy but it never gets called. I don't understand What I done wrong here? Can some one help to solve this? Thank you very much.

Answer 1

You should name local strategy and use it in authenticate.
Use like this passport.use('local-strategy',new LocalStrategy({});
and like passport.authenticate('local-strategy');
