passport.authenticate 不是 function / User.findone 不是 function

Question

**I can't figure out for the life of me of what I am doing wrong. I am very new to passport and js in general but any help would be appreciated, Everytime I try to run in, I get authenticate is not a function. Then if I require passport in my htmlRoutes.js I get findOne is not a function. Very confused **

This is my passport.js

const passport = require("passport");
const LocalStrategy = require("passport-local").Strategy;
const User = require("../routes/htmlRoutes");

passport.use(
new LocalStrategy({ usernameField: "email" }, function (
email,
password,
done
) {
User.findOne({ email: email }, function (err, user) {
  if (err) {
    return done(err);
  }
  if (!user) {
    return done(null, false, { message: "Incorrect Email..." });
  }
  if (!user.validPassword(password)) {
    return done(null, false, { message: "Incorrect password..." });
  }
  return done(null, user);
});
})
);

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

passport.deserializeUser(function (id, done) {
User.findById(id, function (err, user) {
done(err, user);
});
});

module.exports = passport;

My Schema

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const userSchema = new Schema({
first_name: {
type: String,
required: true,
},
last_name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
unique: true,
},
password: {
type: String,
required: true,
},
});

module.exports = mongoose.model("User", userSchema);

My htmlRoutes.js. In Here, if i change passport to require('passport'), I lose the error for authenticate but it doesnt make any sense to me to do it like that

const express = require("express");
const Router = express.Router();
const User = require("../models/User");
const passport = require("../config/passport");

Router.get("/", (req, res) => {
res.render("index");
});

Router.post(
"/login",
passport.authenticate("local", {
successRedirect: "/dashboard",
failureRedirect: "/login",
failureFlash: true,
})
);

Router.get("/dashboard", (req, res) => {
res.render("dashboard");
});

Router.post("/new/users", (req, res) => {
User.create({
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
password: req.body.password,
}).then((data) => {
res.send(data);
});
});

module.exports = Router;

welcome tom StackOverflow. There are a couple of things that I can see.

1. You are not importing the usercollectionSchema into the passport config and rather the userRoutes.js which exports the Router, which most certainly doesn't consists the findOne() function.
2. Secondly, you can go ahead and use require('passport') in the route file.

I'm just writing out the part which needs to be changed, everything else must be obvious.

In your passport.js

...
const User = require("../models/userModel");
...

In your userRoutes.js file

...
const passport = require("passport");
...
