Trying to create signin and signup using express and MongoDB. In postman the data is perfectly passed but couldn't save the data into mongoDB cluster. IN this file connection to the db is created and also confused whether i am connected to the db or not in this file, I created schema for the user details to be provided

//Index.js


const express = require("express");
const mongoose = require("mongoose");
const app = express();
const dotenv = require("dotenv");

dotenv.config();

const db = process.env.DATABASE;

mongoose.connect(db, { useNewUrlParse: true }, () =>
  console.log("connected to db")
);



//midlewares
app.use(express.json());

//importing routes

const authRoute = require("./routes/auth");

//route middle wares
app.use("/api/user", authRoute);

app.listen(3000, () => console.log("gg server is running"));



//User.js


const mongoose = require("mongoose");

const { Schema } = mongoose;

const userSchema = new Schema({
  name: {
    type: String,
    max: 32,
    required: true,
    min: 6,
  },

  email: {
    type: String,
    required: true,
    max: 32,
  },
  password: {
    type: String,
    max: 1022,
    min: 8,
    required: true,
  },

  date: {
    type: Date,
    default: Date.now,
  },
});

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




//Auth.js


const router = require("express").Router();
const User = require("../model/User");

router.post("/register", (req, res) => {
  const user = new User({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password,
  });

  const name = {
    name: req.body.name,
    email: req.body.email,
  };

  res.send(user);

  user.save();
});
module.exports = route[![enter image description here][1]][1]r;

Step 1

First, you should create a server after your MongoDB is connected. So, put your server logic inside mongoose.connect connect. This will assure that when yo u try to create a new user, MongoDB is already connected.

mongoose.connect(db, { useNewUrlParse: true }, () =>
  console.log("connected to db");

  //midlewares
  app.use(express.json());

  //importing routes

  const authRoute = require("./routes/auth");

  //route middle wares
  app.use("/api/user", authRoute);

  app.listen(3000, () => console.log("gg server is running"));
);

Step 2

Use create method to create new user document:

router.post("/register", async (req, res) => {
  const user = await User.create({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password,
  });

  return res.status(200).json(user);
});
