Change enviroment vairables with dotenv

[ripe edge]

Hi,

I have to overwrite some entries in one or more .env files. If the variables has been set with the command line, it would be nice to change these, too.

Currently I use the default ConfigService from the NestJs ConfigModule and applied a custom validator with class-validator and class-transformer. I already did some transformations with these libs, but now I have to write these changes to the files.

The locations of the files are static (in a relative path context).

Is a custom ConfigService a good idee? If so, can I extend the default ConfigService?

i'm not sure if i understood you correctly, so let me know if i didn't
the nest docs mentions creating custom getter functions
perhaps this is what you are looking for?

thanks for your repsonse. I think custom getters are not the best option because they could be run multiple times. But I found out, that I can overwrite the file within the validator.

gues that solves it then huh?
