MongooseError: Operation `products.insertOne()` buffering timed out after 10000ms-CodePudding

I am using Youtube tutorial about API using MongoDB and mongoose. However,I am keep getting this error whenever I do POST something on Postman. "MongooseError: Operation products.insertOne() buffering timed out after 10000ms"

const { MongoClient } = require('mongodb');
const uri = "mongodb srv://dusdn1102:"   process.env.MONGO_PW   "@node-rest-shop.wvxmj.mongodb.net/myFirstDatabase?retryWrites=true&w=majority";
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
client.connect(err => {
  const collection = client.db("test").collection("devices");
  client.close();
});

I am using visual studio code 1.57.1 and the version of MongoDB is 4.4.10. Please can someone help me??

You need to use mongoose to create a connection with the MongoDB. Add the following code to your app.js or server.js first.

const mongoose = require("mongoose");
const uri = "mongodb srv://dusdn1102:"   process.env.MONGO_PW   "@node-rest-shop.wvxmj.mongodb.net/myFirstDatabase?retryWrites=true&w=majority";
mongoose.connect(uri, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});
const db = mongoose.connection;
db.on("error", console.error.bind(console, "connection error: "));
db.once("open", function () {
  console.log("Connected successfully");
});

Use this to open a connection and then proceed with the insert operation.

This will help you.

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/test')
.then(()=>console.log("DB Connected"))
.catch((err)=>console.log(err))

if you're using the mongoose model use this connection setting or as mentioned in mongoose website
