CONNECTING MONGODB WITH EXPRESS

 IN THE CLSUTER, CLICK ON CONNECT,

THEN ON THE NEXT PAGE, COPY THE LINK,

WE NEED TO CREATE A NEW IP ADDRESS 0.0.0.0/0 IT ENABLES SERVERS FROM EVERYWHERE.

IN THE PLACE OF <db_password>  WE PASTE THE PASSWORD THAT WE CREATED DURING THE CREATION OF CLUSTER. WE STORE IT IN THE .env FILE

.ENV

 MONGO_URL=mongodb+srv://marsakatlaabhishek7168:********@pr1cluster.h5ozwrd.mongodb.net

/?retryWrites=true&w=majority&appName=PR1Cluster

LATER, IN index.js FILE WE REQUIRE IT  require("dotenv").config();

const PORT = process.env.PORT || 3002;

const uri = process.env.MONGO_URL;

INDEX.JS

require("dotenv").config();

const express = require("express");

const mongoose = require("mongoose");

const PORT = process.env.PORT || 3002;

const uri = process.env.MONGO_URL;

const app = express();

app.listen(PORT, () => {

  console.log("port listening to 8000");

  mongoose.connect(uri).then(() => {

    console.log("DB connected");

  });

});

in .ENV

 MONGO_URL=mongodb+srv://marsakatlaabhishek7168:_2NQa2KpsiBmAey@pr1cluster.h5ozwrd.

mongodb.net/tradeEasy?retryWrites=true&w=majority&appName=PR1Cluster

WE CAN CUSTOMIZE THE URL
