MongoDB Node Express - data not getting saved while using user.save()

Question

While this one works perfect with postman get "welcome message" and post /login request, gives no error nor saves data in mongo cloud, but shows could not get response in POSTMAN

index.js file

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

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

dotenv.config();

//Connect To DB
mongoose.connect(process.env.DB_CONNECT,
{ useNewUrlParser: true, useUnifiedTopology: true },
() => console.log("connected to DB")
);

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

//Route Middleware
app.use("/api/user", authRoute);

app.listen(3000, () => console.log("Server up and running on port 3000"));

User Schema - User.js

const mongoose = require("mongoose");

const UserSchema = new mongoose.Schema({
    name : {
        type: String,
        required: true,
        min: 6,
        max: 50
    },
    email: {
        type: String,
        required: true,
        min: 6,
        max: 25
    }
    ,
    password: {
        type: String,
        required: true,
        min: 6,
        max: 1024
    },
    date:{
        type: Date,
        default: Date.now
    }
});
module.exports = mongoose.model("User", UserSchema);

auth.js file

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

router.post("/register", async (req, res) => {
  const user = new User({
    name : req.body.name,
    email: req.body.email,
    password: req.body.password
  });
  console.log("Entering Try Catch");
  try {
    console.log(user.name +" - " + user.email);
      const savedUser = await user.save();
      console.log("saved user = " + savedUser);
      res.send(savedUser);
  } catch (err) {
    console.log(err);
    res.status(400).send(err);
  }
});

router.get("/", (req, res) => {
  res.send("Welcome");
});

router.post("/login", (req, res) => {
  console.log("Console Logged In");
  res.send("Logged In Successful");
});

module.exports = router;

It would be of great help, if you could let me know where i'm mistaking. Thanks In Advance !!

Edit : i'm getting all the console till, Entering try catch as well as user.name and user.email

Thanks everyone for your help, well it was not mistake in code or any other error for this one particular what i found is pretty strange, on atlas i allowed access to my current IP address despite that it still had this error now after changing it to Allow Access to all it is working, so i guess it should be the issue from mongo side that they should consider few rare incident like this.

hint: first of all, you should always use return for your responses.

try this :

  try {
    const user = await User.create({
        name : req.body.name,
        email: req.body.email,
        password: req.body.password
    });
    return res.send(user);
  } catch (err) {
    return res.status(400).send(err);
  }
});

You might want to install body-parser middleware for express in order to get the values from req.body

A good way to debug is console.log(req.body) and see if is undefined

Detailed answer here: What does body-parser do with express?

EDIT:

Most likely something with your database connection is the problem, because I'm using your code (copy/paste) and everything works fine for me.

You could add mongoose.connection.on('error', err => { console.log(err); }); below your mongoose.connect inside your index.js to debug your mongoose connection, you should wait around 30s-1min after making POST request.

And here is my .env file : DB_CONNECT=mongodb://localhost:27017/test

``` //Middleware app.use(express.json()); ``` this does the job – Hitesh Oct 12 '20 at 08:52

I edited my answer, does it help to debug? I expect the problem to be at the connection level – Paul Şular Oct 13 '20 at 08:17
Sular : Thank You very much for the help, but one thing which is out of my mind is that i went to mongo atlas created a cluster and copied the url from there which is present in DB_CONNECT. Now i'm wondering what could have gone wrong. BTW it works fine on local machine – Hitesh Oct 13 '20 at 09:37
Hi Paul, could you please point out what could be the issue here as i copied the exact uri from cluster connection, also with the same uri i'm getting a console message as **connected to DB** where as the same thing gives could not get response when sending a GET or POST request – Hitesh Oct 14 '20 at 02:55
