How to Insert Environment Variables in a JSON Config

How do you insert environment variables in a .json config?

I think we need some more context here… The value of the env var or the name of it to be resolved later?
One of the main things about using env vars is that they are not stored on disk.

For development I wanted to put it in a

.env

file

I just don't want to store it in the .json file

Hey Max! What are you looking to put into an env file? There's some information on using env vars here , but I could possibly give you more specific advice if I knew more about the use case!

I don't want the tokens in a public repo

You'll have to use one of the methods described here if you're trying to obscure your tokens.

How do I do this with the .json config? Is there something I can do to add environment variables to a config?

config/@sanity/google-maps-input.json

has a key

apiKey

which I want it to be a environment variable.
