I am getting this error when i am executing this, instead of this i expect to get no error and connect with my mongodb database. enter image description here

Solution

  • Your uri variable is undefined because you are creating it before you call the config() function so process.env.URI is not in scope yet. That's why your MongoDB connection error is being thrown.

    Simply change the order or execution like so:

    const dotenv = require('dotenv');
dotenv.config();
const uri = process.env.URI

    .env

    APPLES='{"name": "gala"}'

    const dotenv = require('dotenv');
dotenv.config();
const apples = JSON.parse(process.env.APPLES);
console.log('apples=', apples.name);
// apples=gala
