Answer 1

Couldn't find it in the docs but passport.use() can receive name as the first param.

passport.use('local-employee', new LocalStrategy(...))

passport.use('local-customer', new LocalStrategy(...))

full example:

const express = require('express')
const passport = require('passport');
const LocalStrategy = require('passport-local');

const app = express();
app.use(require('cookie-parser')());
app.use(require('body-parser').urlencoded({ extended: true }));
app.use(require('express-session')({
    secret: 'BAH',
    resave: true,
    saveUninitialized: true
  }));

passport.serializeUser(function(user, done) {
    done(null, user);
});

passport.deserializeUser(function(user, done) {
    done(null, user);
});

passport.use('local-employee', new LocalStrategy(
    function (username, password, done) {
        console.log(username, password);
        // get user from employee source
        user = {username, password, type: 'employee'};
        return done(null, user);
    }
));

passport.use('local-customer', new LocalStrategy(
    function (username, password, done) {
        console.log(username, password);
        // get user from customer source
        user = {username, password, type: 'customer'};
        return done(null, user);
    }
));

app.use(passport.initialize());
app.use(passport.session());


app.post('/employee/login',
    passport.authenticate('local-employee'),
    function (req, res) {
        res.json(req.user)
    });

app.post('/customer/login',
    passport.authenticate('local-customer'),
    function (req, res) {
        res.json(req.user)
    });

app.listen(3000)
