Question: What is a way to use dotenv-safe?

Hi @andrew-yustyk

Thanks for the suggestion.

You are welcome to make a PR if you can.

I'd be happy to have this functionality optional driven by a safe flag upon initialisation of the ConfigModule something like: ConfigModule.load({safe: true})

By default, I would keep it false.

From the documentation of dotenv-safe looks, that we can use the flag allowEmptyValues to turn on or off the guard.

I'll try to make a PR in the near time

I'm agree with you, that safe option should be optional and disabled bu default.

As for the allowEmptyValues from dotenv-safe, it was creating for the another purposes as far as I understand. Whet allowEmptyValues option is true, dotenv-save allows to define env vars with empty values:

MY_VARIABLE=

but variable still needs to be present even with empty value. In a case when required variable doesn't exist in process.env, an error still will be thrown.

I think will be better to add additional options for dotenv-safe to the ConfigModule.load() method
