I’m building a BoardView app that needs to use a third-party service via API — specifically, the Google Maps Geolocation API, which requires a secret key.

The challenge is that I want to store the API key securely, and not expose it in the client-side code. I think the recommended way to handle this is by using Environment Variables or Secrets, but these are only available in server-side code.

Because of this, I believe I’ll need to create a separate server-side app to act as a proxy for the Geolocation API requests. However, I’m not sure how to properly integrate the server-side app with the client-side app.

Any guidance or examples would be greatly appreciated.

Thanks in advance!
