I'm trying to set configuration variables on my project using the official documentation.

I added the following line to my app.module.ts imports:

ConfigModule.forRoot({
  isGlobal: true
}),

I created a .env file at the root of my project with the following content:

MY_VARIABLE=myself

And I use dependecy injection to get access to the configuration service:

constructor(private configService: ConfigService) {}

However the following line logs 'Env variable: undefined'

console.log('Env variable: ', this.configService.get<any>('MY_VARIABLE'));

• javascript
• node.js
• nestjs
• dotenv

• Sounds like you've got it set up properly. Can you share a reproduction? In the snippets you've provided I can't see a problem. – Jay McDoniel Commented Apr 26, 2020 at 16:08

Several scenarios:

• You don't have .env file
• .env is incorrectly defined
• You're trying to access environmental variables from .env located outside the server's root path
• You need to install dotenv package
• Deploying to Serverless and in the functions (or other deployable folder) the .env is missing (even though it's in the root location it has to be there too)

I have the same problem. Then I figure out that I have imported process from import process from 'node:process'; this is not needed. After removing this its working fine.
