Hello Guys, I am studying about NodeJs and I created an example to help read data from .env config file. And using express help create server, You can see my code here:
index.js
require('dotenv').config();
var express = require('express');
var app = express();
app.get('/', function (req, res) {
res.send('Hello Nodejs');
console.log(process.env.DB_USER);
console.log(process.env.ENV);
console.log(process.env.DB_PORT);
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
.env file
DB_PORT=2088
DB_USER=local
ENV=development
When I run command node index.js I got an exception throw Error: Cannot find module 'dotenv'.

Sometimes I got the same error and I run the commands below and it solved for me:
# 1. delete node_modules and package-lock.json rm -rf node_modules rm -f package-lock.json # 2. clean npm cache npm cache clean --force # 3. re-install dotenv package npm install npm install dotenv@latestHope it also work for you.
