Answer 1

I believe that you have problem in your router configuration. passport.authenticate is generating middleware for you, but in your case you have wrapped it in function so you could log input parameters and you haven't returned generated middleware to router:
router.post('/login' , (req,res,next)=>{
console.log("bodyparser" ,req.body);
passport.authenticate('local',{
session: false
},function(req,res,next){
console.log(res);
})
})
I would advise you to modify your code to work like in example in official documentation:
router.post('/login' , passport.authenticate('local',{
session: false
});
)
If you really need to log req.body just add a middleware before authentication like this:
router.post('/login' , (req, res, next) {
console.log("bodyparser" ,req.body);
next();
},
passport.authenticate('local', {session: false});
)
