usuario.js

 const mongoose = require('mongoose'); const bcrypt = require('bcrypt-nodejs'); const Schema = mongoose.Schema; //= =============================== // User Schema //= =============================== const UserSchema = new Schema({ email: { type: String, lowercase: true, unique: true, required: true }, password: { type: String, required: true } }); // Pre-save of user to database, hash password if password is modified or new UserSchema.pre('save', function (next) { const user = this, SALT_FACTOR = 5; if (!user.isModified('password')) return next(); bcrypt.genSalt(SALT_FACTOR, (err, salt) => { if (err) return next(err); bcrypt.hash(user.password, salt, null, (err, hash) => { if (err) return next(err); user.password = hash; next(); }); }); }); // Method to compare password for login UserSchema.methods.comparePassword = function (candidatePassword, cb) { bcrypt.compare(candidatePassword, this.password, (err, isMatch) => { if (err) { return cb(err); } cb(null, isMatch); }); }; module.exports = mongoose.model('User', UserSchema);

pasaporte.js

 const passport = require('passport'); const User = require('../models/user'); const config = require('./main'); const LocalStrategy = require('passport-local'); // username field is now email const localOptions = { usernameField: 'email' }; // set up the local login strategy const localLogin = new LocalStrategy(localOptions, (email, password, done) => { User.findOne({ email }, (err, user) => { if (err) { return done(err); } if (!user) { return done(null, false, { error: 'Your login details could not be verified. Please try again.' }); } user.comparePassword(password, (err, isMatch) => { if (err) { return done(err); } if (!isMatch) { return done(null, false, { error: 'Your login details could not be verified. Please try again.' }); } return done(null, user); }); }); }); passport.use(localLogin);

Entonces, ahora, solo necesita crear un controlador para manejar la lógica comercial para los registros de usuarios, etc. Por ejemplo,

* UserController.js *

 // other functions // register export function register() { if (!req.body) { res.status(500).json({ error: 'All Fields Required.' }); } const user = new User(req.body) user.save((err, user) => { if (err) { res.status(500).json({ err }); } res.status(200).json({ user }); }) }

enrutador.js

 // other important things to require const passportService = require('./config/passport'); // Middleware to require login/auth const requireLogin = passport.authenticate('local', { session: false }); // your routes go here and you can access requireLogin now, like so: router.get('/users/:id', requireLogin, getUserById); router.post('/users', register);

Espero que esto ayude. No estoy tratando de hacerte cambiar tu base de código, pero esta es una mejor manera de hacer lo que quieres hacer.
