Currently I'm on Monorepo and hosting api at apps/api

Here is the process of reading ENV, should reading .env file on local only, else reading from railway env

import { config } from 'dotenv';


if (process.env.NODE_ENV !== 'production') {
    console.log('Loading .env file', process.env.NODE_ENV);
    config({
        debug: process.env.DEBUG_ENABLE !== 'production',
    })
} else {
    console.log('Producing .env, skipping loading .env file');
}

Here the outout

I use railway dashboard to set .env as NODE_ENV=production

You don't need to do all that, dotenv fails quietly when there is no .env file so you only need to have the following

```js
import "dotenv/config";
```

if you need to have the logs though then make sure you deployed the changes made after adding the service variables

Actually, i test that, but still cannot get environment. I thought dotenv/config cannot ready the .env so it overrides the railways env and delete all current env settings.
Maybe because i use monorepo?

Yes, i am using turbo repo to build and run api

pnpm run build --filter api
pnpm run start:prod --filter api

If you want to pass the global env to current build task, you need to add --env-mode=loose or declear at turbo.json
