Node.js environment variables undefined

I'm trying to use environment variables but when I use the file and run the server, I am getting only PORT variable and all of my other variables are undefined. I'm using nodemon.

.env

PORT=3000
SENDGRID_API_KEY=sometext

package.json

"scripts": {
    "start": "node src/index.js",
    "dev": "env-cmd -f ./config/dev.env nodemon src/index.js"
  }

index.js

const port = process.env.PORT
const apiKey = process.env.SENDGRID_API_KEY
app.listen(port, () => {  
    console.log('Server is up on port '+port)
    console.log(apiKey)
})

If you use -f than it wont care about the environment -e, use one of these.

"env-cmd nodemon src/index.js"

.rc file ./.env-cmdrc

{
  "development": {
    "ENV1": "Thanks",
    "ENV2": "For All"
  },
  "test": {
    "ENV1": "No Thanks",
    "ENV3": "!"
  },
  "production": {
    "ENV1": "The Fish"
  }
}

// Command:

env-cmd -e production nodemon index.js
