Stuck on NodeJS mongoDB find() Query - node.js

Question

I am unable to write the correct query.
I am trying to check if the user already exists in the database and it will respond in Login Successfully Response.
This code is in working position problem lies in Query.
I hope somebody will help
function login() {
app.post("/login/", async(req, res) => {
const query = new Model({
email: req.body.email,
password: req.body.password,
});
const cursor = Model.find(query); // (*Here's the problem*)
console.log(cursor);
if (query === cursor) {**strong text**
console.log(query);
res.send("login successfully");
} else {
console.log(query);
res.send("user does not exist ");
}
});
}
login();
// Model and Schema
const LoginSchema = new mongoose.Schema({
email: { type: String, required: true },
password: { type: String, required: true },
});
const Model = mongoose.model("login_details", LoginSchema);
// Registeration Phase
function registration() {
app.post("/register/", async(req, res) => {
const model = new Model({
email: req.body.email,
password: req.body.password,
});
const result = await model.save();
console.log(result);
res.send(model);
});
}
// Headers
const express = require("express");
const app = express();
const mongoose = require("mongoose");
app.use(express.json());
app.use(express.urlencoded({ extend: true }));
//

Issues with your code
1- You don't need to use new Model({}) to query
2- You're using .find() which returns an array, use findOne() instead
3- You're attempting to check if a mongoose model (with _id) equals a query without the _id which won't work
4- Use return at the end of your function (won't affect the functionality here but just as good practice not to encounter errors like cannot set headers after they're sent)
possible solution
function login() {
app.post("/login/", async (req, res) => {
const cursor = await Model.findOne({
email: req.body.email,
password: req.body.password,
});
console.log(cursor);
if (cursor) {
console.log(cursor);
return res.send("login successfully");
} else {
return res.send("user does not exist ");
}
});
}

You are using Mongoose in the wrong way. Try this.
const result = await Model.find({
email: req.body.email,
password: req.body.password,
});
