How to Use Environment Files (.env) in Node.js - Tutorial (dotenv)

In today's video I'll take you through using .env files in NodeJS - this is done using the popular "dotenv" package.
.env files are used to store environment-specific configuration or settings for your application so it can easily be ran on various environments. Things like database credentials, API keys or URLs for 3rd party resources can be stored in them.

Great video!
For those working with ES6 and who could face some trouble, you could use this :
`import dotenv from 'dotenv';
dotenv.config();`
instead of require().

[@bhaskargowda-3955]

Thanks a ton manhh

[@cm3462]

another way :
import { config } from 'dotenv'
config()

[@carolinaaa-d4h]

thanks for the video , just on point. Before watching this video I had to read multiple useless blogs that were long and still were not clear enough and incomplete.

[@SuperYtc1]

2:27 is when the vid starts

[@GuilhermeSiebert]

[@peanutcelery]

If your .env is named different like .env.local then you pass the options in config:
config({path: "./.env.local"})

[@GiuseppeGreco-jl7dx]

Quick and easy. Thanks a lot!

[@danielfan9196]

I LOVE YOU SO MUCH EVERY OTHER VIDEO DIDN'T WORK I LOVE YOU

[@kennethsolomon2178]

Thank you so much ! Created my first .env file LOL.

[@yidan_wang_ittan]

Thank you so much! Help me clear my doubt!!!

[@dcode-software]

You're welcome 😊

[@anounTT]

FYI: The .env file has to be where you start the application. I had index in /src/index.js, and env '/' and my start script was 'cd src && nodex index.js' and it did not detect my env variables. In the video you said in the root, but not all applications start from the root.

[@adaninz4340]

I had the same probleme but I put the .env file in src and requiere dotenv module like this: require(“dotenv”).config({path:”src/.env”});

[@aseo9524]

Was having the same issue, your comment helped me. Thanks!

[@jorims8537]

Why do I need the dotenv dependency though? Can't I just add properties to the process.env in a seperate file and import them to the other sheets ?

[@patrick_kabwe]

if you're ever having issues with .env. for example if it is saying something like needs to be a string...make sure your .env file is in the root of your project

[@mochalo4912]

[@DmitryLubenskiy]

And how do I setup env in production after deployment?..

[@grantdoyle1259]

trying to use a env file in a vite project but getting this: Uncaught ReferenceError: require is not defined

[@DawitMengistuAbajifar]

.env file should be outside of any folder like routes or any other
that solved my undefined problem.

[@crazyboyrish2577]

Thanks alot brother you saved my day❤

[@twizzy5083]

mine is outside of any folder and i still get undefined :(

[@harshilpatel3389]

[@dcode-software]

The theme I'm using is called "dcode" and I made it for my UA-cam videos. You can find it on VS Code marketplace

[@twizzy5083]

i wish this worked for me i keep getting undefined

[@aminamini9191]

[@shayanvaliyari8232]

It could be better if u separated the introduction to .env and the usage guide into two even shorter videos just so people get faster answers from your channel

1) I don't care what your name is.
2) I can read the title of the video, that's why I clicked on it.
