How to read environment variables in a Node project?

[imdavidmin]

In my JS code I would like to read from an environment variable I've set on the deta CLI.

With import { os } from 'os'; , os.getenv is showing as not valid with typescript checking. process.env wasn't working before.

You need to install dotenv module first

// npm install dotenv

const dotenv = require('dotenv')
dotenv.config()

// using environment variable SECRET_KEY
const secret_key = process.env.SECRET_KEY

Please delete this thread - process.env works without using dotenv. My error was generated from somewhere else.

You do not use .env file?
