Setup environment variables with Node.js + Dotenv Tutorial

In many application, it's always a good idea to set up environment variables to protect your tokens, passwords, db connection strings, etc. It's also great for having one reference to a variable that may change.

Tip: You can 'npm init -y' to automatically "enter out" all questions; it'll create a default package.json

[tannaurus]

Helped wrap my mind around this, thanks man!

[danielEpifanov]

I wrapped my mind around this, thank you

[PrestonL]

Thank you Dev! You explained that perfectly

Great video, good tips. You do a good job at explaining things that others assume the user will know about, such as the .gitignore. I know that technique takes a bit longer, but I remember when I first started learning this stuff and how much I appreciated when presenters would use a few assumptions as possible. I'm sure this will be helpful to many just getting started.

That's a really useful module. An equivalent to this would be running your index.js with the following command: node index.js`

Thank you very much. Very much useful. I wanted to protect mongoDB password from mongoose connect.

Thank you. You showed me what the issue was for me, I was doing require('dontenv') intead of require('dotenv/config'). Without importing the config, you don't have access to the local config.env file from your project.

You just made me make .env file and a cup of coffee

[simonkalu]

Concise and informative. You're a great teacher. Though, a bit fast

[shriiikaant]

Can you please tell me, Would there be different .env files for different environments? How can we trigger them from maven pom (React+Spring) app?
