How can I use a .env on my renative project?

[mendoza]

Hi everyone!
I'm working on a TV app right now, and I want to be able to use .env files for certain configurations (like the base url for the api),
I tried using a field on my runtime config on my renative.json with {{env.BASE_URL}} however these only works with env variables set on the command line. After that, I tried using react-native-dotenv or anything like that, didn't really affected the process.env on the React code.

Is there a specific way I haven't seen?

I found the renative.private.json file that could be used instead of .env files, however I would like to also know if it's possible to use them.

@mendoza hello, thanks for this question, have you tried using dotenv package? I know we have used it with great success

[mendoza]

I tried running it on tv (or in native really, I get some error about crypto, fs and other libraries dotenv uses)

@mendoza Can you create a ticket with described issue, reproduction sequence and logs? thank you

[mendoza]

Sure let me get you that, before I do, where would you call the dotenv.config? I think my questions would boildown to, what would be the entry point for dotenv

I resolved using Next env. Create your .env.local file and put your vars with NEXT_PUBLIC_ prefix for each

This solution works only when the platform is web.
