export default config.getProperties()

been trying to get this to work for days now, Have been able to use convict to read .env files

const envPath = join(__dirname, '..', .env.${env})
dotenv.config({ path: envPath })

In this example, you'll want a '.env.production' file in the directory above the config.js file.
You can just load the .env file using dotenv.config() function

Thanks AnsonT, I realised I was not setting any values in the .env file.
