RFC: Providing support for non-node.js backends (Python FastAPI)

[nikkiam]

Hey, not sure where to put this, but the Q&A link in the contributing guide was broken. I have a port of the @hashbrown/google package to Python that is FastAPI compatible, and I was wondering whether the Hashbrown team had interest in officially or unofficially supporting non-JS backends in the docs.

I wanted to integrate my frontend implementation of the hashbrown.dev library in React with my existing FastAPI backend instead of spinning up a dedicated Express server just for processing OpenAI/Gemini requests. In doing so, I discovered that the basic chat functions are easy to port to Python for both OpenAI and Gemini, but with the useStructured* hooks, I had to make some minor changes to get things working.

I now have what I think is working, "pip package"-able code to translate from useStructured* hook backend request format to the Gemini API request format (using the google-genai python SDK). I validated my code by writing a script to check that identical Gemini requests are produced for the same useStructured* hook-based request by both of my locally running Express + @hashbrown/google and FastAPI + my port servers. Happy to keep it for my own use, but I thought I'd let you know!

I'd personally love that! Please create a PR, doesn't have to be perfectly integrated into the monorepo. I can help get it over the finish line.

Thank you so much!
