authentication with passport passport local mongoose code example

Example 1: passport local mongoose

const User = require('./models/user'); 
// CHANGE: USE "createStrategy" INSTEAD OF "authenticate"
passport.use(User.createStrategy()); 
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

Example 2: passport local mongoose

// requires the model with Passport-Local Mongoose plugged in
const User = require('./models/user');

// use static authenticate method of model in LocalStrategy
passport.use(new LocalStrategy(User.authenticate()));

// use static serialize and deserialize of model for passport session support
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
