Is there a way to use environment variables inside .env to expand to its value ?

We have use case to use environment variables that are created by kubernetes container.
Is there a way to use process.env variables to expand inside .env file?

REACT_APP_HELLO=$USERNAME

I am looking similar to what react-env does
npx react-env --path .env --dest dist

The output will replace $USERNAME with environment variable value.

You could use @import-meta-env/prepare (with -u, --user-environment) to dynamically generate .env from something like .env.defaults and process.env. 😄
