SignUp form with NodeJs mongodb(mongoose) express using passport

Question

I am having a signup form with fields like username password email, i am using mongodb to store these data my schema looks like:

var mongoose = require("mongoose");
var Schema = mongoose.Schema;
const passportLocalMongoose = require("passport-local-mongoose");
 var User = new Schema(
  {
    username: {type: String, required: true,unique: true },
    password: {type: String,required: true },
    email: { type: String, unique: true, required: true },
    admin: { type: Boolean, default: false }},
  { usePushEach: true},
  {timestamps: true }
);    
User.plugin(passportLocalMongoose);
module.exports = mongoose.model("User", User);

i have a middleware before hitting the endpoint with the following code:

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var User = require('./models/user');

exports.local = passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

i have an end point to hit signup and i have written this :

router.post("/signup", (req, res, next) => {
  Users.register(
 new Users({ username: req.body.username,email:req.body.email }),
 req.body.password,

 function(err, account) {
   if (err) {
        res.statusCode = 500;
        res.setHeader("Content-Type", "application/json");
        res.json({ err: "err" });
      }
      passport.authenticate("local")(req, res, function() {
        res.send("/books");
      })})});

when i pass the json object with username password email after the changes i got this error in postman

{
    "err": {
        "errors": {
            "password": {
                "message": "Path `password` is required.",
                "name": "ValidatorError",
                "properties": {
                    "message": "Path `password` is required.",
                    "type": "required",
                    "path": "password"
                },
                "kind": "required",
                "path": "password",
                "$isValidatorError": true
            }
        },
        "_message": "User validation failed",
        "message": "User validation failed: password: Path `password` is required.",
        "name": "ValidationError"
    }
}

can anyone help me in this whether i am having issue with npm package or is there any call back i have to handle,I cant figure out!

It looks like you don't want to define the password in your schema. Passport-local-mongoose will take care of that for you!

"You're free to define your User how you like. Passport-Local Mongoose will add a username, hash and salt field to store the username, the hashed password and the salt value." - https://github.com/saintedlama/passport-local-mongoose

Try this instead:

var mongoose = require("mongoose");
var Schema = mongoose.Schema;
const passportLocalMongoose = require("passport-local-mongoose");
 var User = new Schema(
  {
    username: {type: String, required: true,unique: true },
    email: { type: String, unique: true, required: true },
    admin: { type: Boolean, default: false }},
  { usePushEach: true},
  {timestamps: true }
);    
User.plugin(passportLocalMongoose);
module.exports = mongoose.model("User", User);

router.post('/signup', (req, res, next) => {
  Users.register(
    new Users({ username: req.body.username, email: req.body.email}),
    req.body.password,
    function(err, account) {
      if (err) {
        res.statusCode = 500;
        res.setHeader('Content-Type', 'application/json');
        res.json({ err: 'err' });
      }
      passport.authenticate('local')(req, res, function() {
        res.send('/books');
      });
    }
  );
});

Let me know if that solves your problem.
