Support for Vite

[steffen12]

Is your feature request related to a problem? Please describe. We would like to use your package, but it seems that it only supports projects that are made using Create React App due to the way that the environment variables are fetched.

Describe the solution you'd like We are now using Vite for our project instead, and I know that Vite is also becoming very popular among other developers. I would like to kindly request that you offer support for users who built their apps using Vite as well.

Describe alternatives you've considered We are considering the standard individual packages (react-facebook-login, etc.) instead of this package
