.env file

[iPagar]

Hi!
Is there a way to load env vars from a file?

For example nixpacks build ./path/to/app --envFile ./.env --name my-app?

There isn't at the moment, but would be a great feature to add! I think we could even do it automatically (if there is a .env file in the app root then load it)

[iPagar]

Yeah! Do it automatically would be great!

I found two ways of doing this now:

1. nixpacks build . --name my-app --build-cmd 'set -a; source .env; set +a; npm run build'
2. nixpacks build . --name my-app --build-cmd 'export $(xargs < .env); npm run build'

It's working perfectly! 😼

So like dotenv but without the package, good idea!

I think we can handle it in a similar way to how the Procfile detection works. If there is a .env file found then parse and load all of the variables into the environment

We can provide both options, --envFile if users wants to provide different env file, and detect .env by default?
