cant get data from form to server - MERN

im new and i cant get data from the form in server to insert it in the DB, heres the code:

form:

<form method = "post" action = "/register">
            <label>
                User Name:
                <input type = "text" name = "user" onChange = {(text) => setUser(text.target.value)}></input>
            </label>
            <label>
                Password:
                <input type = "password" name = "password"></input>
            </label>
            <input type = "submit" name = "Send" value = "Send"></input>
</form>

and the server.js:

const express = require("express");
const app = express();
const bodyParser = require("body-parser");
const cors = require("cors");
const mongoose = require("mongoose");
const PORT = 4000;
app.use(cors());
app.use(bodyParser.json());
mongoose.connect("mongodb://127.0.0.1:27017/Cook", {
    useNewUrlParser: true,
});
const connection = mongoose.connection;
app.post("/register", function(request, response) {
    let user = request.body.user;
    let password = request.body.password;
    console.log(user)
})

if anyone can help, would appreciate it :)
